EPSITRON® PRO Power Supplies
Professional and efficient power supplies with extra power
Applications with high output requirements call for professional
power supplies capable of reliably handling power peaks. These
applications call for EPSITRON® PRO power supplies, which provide 24VDC with nominal output currents of 5A to 40A in a slim
vertical- or horizontal-mount housing. An integrated PowerBoost
function provides 200% of the rated current for up to 4 seconds,
enabling start-up or switching of capacitive loads, valve clusters
or motors.
The TopBoost function provides sufficient power with a multiple of
the rated current for up to 50ms, permitting use of standard circuit
breakers for output protection. An optional LineMonitor provides
easy parameter setting and monitoring of input and output powers.
This eliminates redundant devices, such as phase and frequency
monitoring units, as well as operational hour meters in control
cabinets. The PRO family of power supplies set a new standard in
energy-efficiency with up to 93% efficiency and a stand-by mode.

Innovative and communicative
1. Via LEDs: A green LED indicates error-free operation. Critical errors (e.g., overload
or short-circuit) are indicated by a red LED on the output. For the PRO series devices with
LineMonitor, a yellow LED warns of non-critical errors such as the failure of a phase.
2. Via display: PRO Power Supplies with integrated LineMonitor have a display and on-unit
keys for direct parameter setting and on-site monitoring. In addition to setting the output
voltage and overload behavior, it is also possible to set permanent current and voltage
monitoring on the output and extensive power monitoring on the input. The device features
an integrated fault memory for self-diagnostics in the event of errors.

3. Via active signal output/isolated contact: LineMonitor-equipped models (787-850,
787-852 and 787-854) offer four active signal outputs for function monitoring on the front
of the device. The corresponding states can be then transferred to higher-level control systems
as a digital 24V signal. Two signal outputs can be user-defined via free 759-850 configuration software, e.g., for the purpose of generating a group signal for all critical states. Singlephase PRO series devices use an isolated contact to signal an undervoltage on the output.

4. Via serial RS-232 interface: PRO Power Supplies with LineMonitor can communicate
with a PC or PLC via front-side serial interface. The 759-851 Software displays all relevant
data on a PC; parameter setting is performed via 759-850 Software.

Both versions can be downloaded free of charge at www.wago.com/epsitron.
The 787-890 serial communication cable is available as an accessory for connection
to the RS-232 interface.
High-performance and adaptable
The PRO Power Supplies provide extra power via TopBoost and PowerBoost. In addition,
the overload behavior of devices equipped with LineMonitor can be adjusted, allowing
them to adapt to the application.

PowerBoost
During start-up or switching of capacitive loads (valve clusters, motors, etc.), there is an
increased need for current that conventional switch mode power supplies cannot deliver
without PowerBoost due to the limited output current, typically 1.1 times the rated current.
The PRO Power Supplies offer power reserves here, providing 200% of rated current at
24VDC for up to 4 seconds. This ensures reliable loads operation and eliminates the need
for expensive oversizing of switch mode power supplies.
TopBoost
In order for high-speed magnetic miniature circuit breakers to trip, currents that are significantly higher than the rated current are required for a period of 10 to 12 milliseconds.
PRO Power Supplies deliver a multiple of the rated current for up to 50ms; this means the
faulty circuit can be shut off within milliseconds during a short-circuit. This increases the
availability of the entire power supply and also fulfills the requirements of EN 60204-2
with respect to grounding in control circuits.

EPSITRON® CLASSIC Power Supplies
The robust power supply for various voltage ranges
Electrical machines and systems have various voltage and power
requirements. 12V, 24V or 48V DC source is often required, as is
30.5V to supply AS-Interface networks. CLASSIC Power Supplies
featuring various output voltages are ideally suited for such applications. The CLASSIC devices with 1-phase wide range of input
voltages offer output currents of 1.3A to 10A, making worldwide
use possible when combined with available approvals. All devices
feature an output voltage adjustable via potentiometer along with
clear status indication in order to compensate for power losses.
The clearly visible green display indicator (DC OK) makes start-up
easy. CLASSIC devices with output power > 150W also indicate
an overcurrent or short-circuit with a red LED. The integrated constant current characteristic for output power > 40W permits start-up
of capacitive loads.
Pluggable CAGE CLAMP® connections, a robust metal housing
and up to 90% efficiency are additional advantages that make
CLASSIC Power Supplies well-suited to industrial use.

Uout [V] Ñ
Iout [%] Ñ
The wide range of input voltages of the CLASSIC Power Supplies allows feeds of
90 to 264VAC. This enables a mass-produced machine to be operated on different power
networks in Europe, America or Asia without additional conversion or adjustment. This also
increases the operating reliability of the power supplies if there are deviations from the rated
voltage in the supply network. The CLASSIC Power Supplies can also be supplied with DC
power and be used as DC/DC converters. The CLASSIC also carries multiple approvals,
making it ideal for worldwide use.
High load-carrying capacity
Overcurrent phase
Loads frequently have an increased need for current when switched on. Power supplies with
constant current characteristics – such as the 24VDC and 48VDC CLASSIC devices with output power > 40W – deliver 1.1 times the nominal rated current with lowered output voltage.
This makes them ideal for starting capacitive loads, for example.

Always informed
All CLASSIC Power Supplies have an operating indicator signaling the availability of the output voltage via a green LED. Devices with output power > 150W also have an overcurrent
indicator, indicated by a red LED. This makes start-up easier and rapidly provides maintenance personal with system or machine status.
Finely tuned output
The longer the connection wires and the smaller the wire cross-section, the greater the
output resistance. To ensure the load has sufficient operating voltage, even at the end of
long wires with small cross-sections, power supply output voltages can be increased by
up to 20%. Conversely, lowering the output voltage is also possible, which can reduce
the current consumption. The output voltage can be set using a screwdriver via the potentiometer; this is accessible from the side or above the unit.

All ECO Power Supplies signal the availability of the output voltage via green LED operation indicator. A red LED indicates an overvoltage. This simplifies start-up and rapidly provides maintenance personal with system or machine status.
High load-carrying capacity
Overcurrent phase
Loads frequently have an increased need for current when switched on. The ECO Power
Supplies with constant current characteristics deliver 1.1 times the nominal rated current with
lowered output voltage – ideal for starting capacitive loads, for example. For low-ohm short
circuits, the output voltage is reduced to zero and automatically reinstated as soon as the
short-circuit has been eliminated.

EPSITRON® Electronic Circuit Breakers
Primary switch mode power supplies provide a rapid response
to overcurrent conditions on the output side, extending operating life. Selective protection of individual current paths on the
secondary side via standard circuit breakers is often ineffective
when TopBoost function is unavailable for high-speed magnetic
tripping, unlike for PRO Power Supplies.
Electronic circuit breakers provide selective protection for power
supplies without TopBoost feature. Up to four current paths can
be protected via 4 channels and an easy-to-adjust rated current.
The short-circuit current is limited via an active current limiting
circuit breaker, preventing voltage drop across adjacent current
paths. In addition to parameter setting, the display and serial
interface control both the integrated fault memory and the instantaneous values of the output current and voltage. This provides
proactive monitoring, fault diagnostics and energy monitoring.

Rated currents can be set separately for each channel in 1A increments. In the event of an
overcurrent, the affected channel will be shut down safely and reset per stored protection
characteristic. The 787-861 Circuit Breaker provides active short-circuit current limitation to
1.5 times its rated current, preventing a voltage drop in one current path affecting others in
the event of a short-circuit. Current path trip times may also be configured. Once a channel has
been shut down, it can be reactivated via on-unit keys or by an impulse at the remote control
input of the 787-860 or 787-862 Circuit Breakers.

EPSITRON® Uninterruptible
Power Supplies (UPS)
Unpredictable power failures are a nightmare for any machine or
equipment operator. If a PLC is suddenly shut down due to a power
failure, the loss of production data (e.g., formulations or protocols)
may follow. To prevent these losses, the Uninterruptible Power Supply, consisting of UPS charger and controller (787-870 or 787-875),
and one or more connected batteries, reliably power the application
for several hours. The charging voltage for the connected battery is
temperature-controlled, which significantly extends the battery‘s service life and minimizes maintenance costs. The UPS module supports
a complete current and voltage monitoring while featuring numerous
signaling options via display and RS-232 interface.

EPSITRON® Capacitive Buffer Modules
Brief power supply failures jeopardize the trouble-free operation
of machines/systems. The power supply buffer times of particular
applications can be considerably extended via capacitive buffer modules. These modules have power reserves that may be
required when starting heavy loads or triggering a fuse. The 787-
880 and 787-881 Buffer Modules contain “gold caps“ to store
energy and are absolutely maintenance-free, providing output
power for 400ms. Buffer times up to several seconds can be easily
achieved by connecting the modules in parallel or adjusting the
output current.

Multiple buffer modules can readily be parallel-connected to
increase the buffer time or the load current. The module outputs are
decoupled from the inputs, making it possible to specifically buffer
just selected consumers.
1. Via LEDs: There are 3 LEDs to signal individual operating conditions. The green LED indicates error-free operation. The red LED
indicates undervoltage at the buffered module output; a yellow LED
signals module charging.

2. Via isolated signal contact: Once the internal charging procedure is complete and there is sufficient voltage at the buffer module
input, the isolated signal output is activated. The contact is deactivated as soon as the module runs out of charge and the control level
can respond to this change of state.
EPSITRON® Redundancy Module
The 787-885 Redundancy Module contains two high-performance
diodes with 20A capacity and decouples two power supplies
connected in parallel. With the connection of two equal power
supplies, the availability of the machine or system is assured or the
load current doubled.
The possible failure of a power supply is indicated reliably via LED
and an isolated contact. With the use of the redundancy module
to increase availability, for example, it is possible to swap devices
during operation without creating downtime.
