*NiCad Battery Charge Parameters
Caution! When configuring for NiCad use, the Battery Charging Level adjustment on front panel must be set to at least 30%
of the capacity of the battery being charged (ie at least 30% of battery rated Amp-Hour capacity), (Note, the adjustment
range of Battery Charging Level dial on the unit is 2 amps minimum, 10 amps maximum.)
If set below the prescribed 30% minimum Ah capacity, the control circuit may not be able to sense battery absorption
rate, and thus not terminate absorption charge cycle until 16 hours has passed, potentially resulting in battery
overcharge.
Float Charge: Constant current, rate =10% of the set Battery Charging Level
Absorption Charge: 62.0 VDC (1.55 VPC x 40 cells).
Termination of absorption charge is determined by an automatic battery test applied after entering absortion mode:
• If test indicates battery will not maintain its voltage (ie drops by > 0.2 volts) absorption mode will continue for a
maximum 16 hours before reverting to float mode.
• If test indicates battery voltage is maintained (i.e. drops <0.2 volts), absorption mode times out after 10 minutes, and reverts to float mode.

1) General Information
This DIN rail mount DC UPS Combines all system power functions: power supply, battery charger, UPS circuitry and status
monitoring in one compact unit that produces 48 volt, 10 amps allocated via dual outputs for load and battery:
• Load output: “load priority” distribution ensures power is dedicated first to the load, with remainder then allocated to
battery charging, thus preventing a discharged battery from impacting operation of critical loads.
• Battery output: 3 step charging for rapid battery recovery, programmable for battery type, with optional temperature
compensation sensor
• Battery automatically on line to support load anytime AC fails
• Low voltage disconnect protects battery from total discharge
• High operating temperature range to 70˚ C
This DC UPS is fitted with special monitoring and alarm features designed to comply with the latest codes related to public
safety in-building wireless communications back-up power requirements, as set forth by NFPA, section 1221.
In normal operation, the unit supplies power to the transmitter/antennas and maintains the back-up battery. Should
an event occur that could cause interruptioin in power, self-diagnosis signals are sent via form C contacts notifying
the network operators the system is running in a critical power condtion and that potential communications failure is
imminent.

Materials Provided:
1 ea. BDS-DIN-UPS unit with integral DIN rail mount clip
4 ea. Jumper tabs for programming
1 ea. Jumper wire (orange) for 115 volt input operation
Optional Equipment:
Temperature Compensation Sensor, P/N: 468-4510-0
2) Safety Information
WARNING – Explosion Hazard. Do not disconnect loads or battery unless AC input and battery have been
switched off.
WARNING – Explosion Hazard. This product is not certified for Class 1, Div 2 applications.
WARNING – Switch off or remove AC input and battery power before wiring the BDS-DIN-UPS-48-10. Never
work on the DIN UPS when it is connected to AC input and battery. The DIN UPS must be installed in
accordance with UL508 or local electrical codes depending upon the application. The DIN UPS should have a suitability
sized AC input circuit breaker feeding its AC input. See specification section for maximum AC input draw for your input
voltage for circuit breaker sizing.
CAUTION: Hot surface. Avoid touching the DIN UPS case while operating at or near its full load capacity. Remove AC and
battery power and allow DIN UPS at least 10 minutes to cool before removing from DIN Rail.
3) Installation/Wiring
A) Mounting:
The unit is designed for 35 mm DIN rail mounting in an enclosure and relies on convection (free air) cooling, thus must
have a minimum vertical and horizontal distance to adjacent surface of 4” (10 cm) to this power supply in order to assure
sufficient air flow. Note, that depending on the ambient temperature and load of the device, the temperature of the case
can become hot to the touch.
4
The unit is designed for vertical mount (+/- 5˚) and has an integral clip on the back to secure it to the rail. To mount, place
the top tabs over the top of the DIN rail, and using a long slotted screw driver insert it in the groove at the bottom of the

2. Output
The unit has dual output circuits: one for connection to the Load, the
other to the back-up battery. Note: the unit has a load priority circuit,
all produced power first is made available to the load with remaining
power made available for battery charging. Both outputs are isolated
from the case thus you may apply to a positive or negative ground
system. Note however, the LVD circuit is in the positive side thus this
feature will not function in -48VDC positive ground application utilizing
a common positive ground bus bar for battery and load.

Note that when wired to positive ground applicatons the LVD function does not operate. (See also Section 4-C regarding
operation with battery time out circuit)
6) Protection
On the AC Input: the device is equipped with an internal fuse. If the internal fuse is blown, it is most probable that there is
a fault in the unit. If this occurs, the unit must be returned to the factory.
On the DC Ouput Battery and Load: The device is electronically protected.
Reverse polarity: the module is automatically protected against reverse of battery polarity and connection of reverse
polarity.
Over current and output short circuit: the unit limits the output current. Low voltage disconnect protects battery from deep
discharge.
Thermal Protection
Operating temperature range -12 to 70˚ C. Unit will produce full rated power on continuous basis to 50˚ C, however;
system load must be reduced by 2.5% per 1˚ for continuous operation above 50˚ C. If the temperature reaches 70˚ C, the
unit will reduce its maximum output to approximately 50% of its rating. If the temperature exceeds 70˚ C, the unit will shut
off and restart once temperature drops.
