Power Boost
This power/ current is continuously allowed up to an ambient temperature of 45°C.
Above 45°C, do not use this power/ current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
**)
HiccupPLUS Mode
At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the
output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the
overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3
***)
Discharge current of output capacitors is not included.
****) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not a
guaranteed value which can be achieved. The typical value is about 28.5V.
*****) Reduced pulse length for AC 100V mains.

*)
The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the
capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be determined if the failed unit
has been running for 50 000h or only for 100h.

23.2. YR20.242 - REDUNDANCY MODULE
The YR20.242 is equipped with two input channels, which are individually decoupled by utilizing
MOSFET technology. Using MOSFETSs instead of diodes reduces the heat generation and the
voltage drop between input and output. The YR20.242 does not require an additional auxiliary
voltage and is self-powered even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 32mm width on the DIN-rail.
The YR20.242 can be used for n+1 and 1+1 redundancy systems.
Further information and wiring configurations can be found in chapter 24.7.
23.3. YR20.246 - REDUNDANCY MODULE WITH AUTOMATED LOAD SHARING
The YR20.246 is equipped with two input channels, which are individually decoupled by utilizing
MOSFET technology. Using MOSFETSs instead of diodes reduces the heat generation and the
voltage drop between input and output. The YR20.246 does not require an additional auxiliary
voltage and is self-powered even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 32mm width on the DIN-rail.
The YR20.246 is optimized for 1+1 redundancy systems.
Compared to the YR20.242, the YR20.246 is featured with an automated load sharing between the
connected power supplies. The YR20.246 monitors the function of the redundancy circuitry and
provides a signal in case of too high of output current, which could prevent redundancy, if one
power supply fails.
Further information and wiring configurations can be found in chapter 24.7.

24. APPLICATION NOTES
24.1. PEAK CURRENT CAPABILITY
The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents.
This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state
coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state
current and usually exceeds the nominal output current (including the PowerBoost). The same situation applies when
starting a capacitive load.
The peak current capability also ensures the safe operation of subsequent circuit breakers of load circuits. The load
branches are often individually protected with circuit breakers or fuses. In case of a short or an overload in one branch
circuit, the fuse or circuit breaker need a certain amount of over-current to open in a timely manner. This avoids
voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the built-in large sized output capacitors of
the power supply. The capacitors get discharged during such an event, which causes a voltage dip on the output. The
following two examples show typical voltage dips:

current for 5ms, typ.

current for 50ms, typ.

24.2. BACK-FEEDING LOADS
Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called
return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply.
It does not matter whether the power supply is on or off.
The maximum allowed feed-back-voltage is 35Vdc. The maximum allowed feed-back peak current is 40A. Higher
currents can temporarily shut-down the output voltage. The absorbing energy can be calculated according to the
built-in large sized output capacitor which is specified in chapter 6.
24.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only
required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In
some countries local regulations might apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or C-Characteristic breaker should be used.
24.4. OUTPUT CIRCUIT BREAKERS
Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and
may also be used on 24V branches.
MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to
the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.
To avoid voltage dips and under-voltage situations in adjacent 24V branches which are supplied by the same source, a
fast (magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly to
the ride-through time of PLC's. This requires power supplies with high current reserves and large output capacitors.
Furthermore, the impedance of the faulty branch must be sufficiently small in order for the current to actually flow.
The best current reserve in the power supply does not help if Ohm’s law does not permit current flow. The following
table has typical test results showing which B- and C-Characteristic MCBs magnetically trip depending on the wire cross
section and wire length.

24.8. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors,
such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance larger than 1.5F are connected to the
output, the unit might charge the capacitor in the HiccupPLUS mode (see chapter 6).

Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a
limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy
of the power supply. Therefore, two different derating curves for continuous operation can be found below:
Curve A1
