Battery Power System Highlights

SENS 63 Series Battery Power System (BPS) is the ideal DC battery backup source for microwave repeaters, small cell sites, RTU and SCADA. The weatherproof housing means the 63 BPS can be installed in nearly any outdoor location.

Nonstop DC power
The 63 BPS is a factory-packaged DC power system that supplies nonstop DC power to keep equipment running despite commercial power failure. The 63 BPS includes filtered rectifier/charger, alarm system, battery and load-control equipment.

63 Battery Power System Closed
Weatherproof housing
The weatherproof housing eliminates the need for an equipment shelter, thus saving costs and space. High-gloss white enamel reflects heat and minimizes dirt build up.

Small size
Rectifier/charger and battery are housed in the same compact, all-welded aluminum cabinet. The small cabinet is easily mounted on walls, equipment towers or antenna poles.

Single system responsibility
All system elements are packaged inside the 63 BPS cabinet.

Temperature compensated, precision rectifiers/chargers
Rectifiers/chargers are precision voltage regulated and temperature compensated. Temperature compensation extends battery life, eliminates over- and undercharging and reduces the risk of battery thermal runaway.

115/230 VAC, 50/60 Hz input
SENS 63 BPS is designed for service nearly anywhere in the world. Standard units operate on either 50 or 60 Hz; input voltage is field-selectable for 115 or 230 volts.

Automatic protection systems
The thermostatically controlled, ball-bearing cooling fan operates above 40 C only. This prolongs fan life and reduces dust ingress into the system. Washable dust filters further reduce the level of dust ingress. An optional thermostatically controlled battery heater is available for systems operating in cold climates. The complete alarm system includes Form C contacts that provide remote indication of system status.

Product Specification
Battery Power System Type 63

General

The Battery Power System (BPS) supplies nonstop DC power to critical loads requiring a well-filtered output. System elements include a filtered rectifier/charger, VRLA battery, load control equipment and a weatherproof housing.

Power Circuit Description
Phase-controlled full-bridge rectification using SCRs. Battery and rectifier/charger output are connected in parallel and supply a low voltage load disconnect. The load disconnect removes the load from the battery when battery voltage drops below the 1.75 volts per cell, and it automatically reconnects it when battery voltage measures over 2.1 volts per cell.

Mechanical Configuration
Rectifier/charger and battery are in different compartments of the same cabinet.

Output

Output voltages
12, 24 or 48 volts nominal.

Output current
6, 12 or 25 amps. (Max current per 48V rectifier/charger is 12 amps). Current limit is made at the factory and cannot be changed in the field. Dual rectifiers/chargers of the above capacities can be accommodated for either higher current or for redundancy.

Output regulation
The temperature-compensated output voltage remains within + 1% of the correct level for any load current over the input voltage and frequency range specified

Output Voltage Temperature Compensation
The output voltage is temperature compensated to .18% per degree Celsius. Battery temperature sensing is accomplished by a sensor located in the battery compartment. In case of a sensor failure or disconnection, sensing automatically reverts to a sensor located on the control card.

Voltage Sensing
Voltage sense is at the output terminals.

Current Limit
The output is electronically limited to between 100% and 105% of rated output.

Input

Rated Input Voltage
115/230 volts +10%, 47-63 Hz, field selectable.

Soft Start (current walk-in)
Upon application of AC power, the rectifier/charger is governed so that output increases gradually to full power, or to a lesser amount as demanded by the load, over a period of approximately 10 seconds.

Protection

Current Limit
Electronic current limit protects from overload and short circuit under normal conditions.

Fault Protection
 

bulletTwo-pole input breaker.
bulletTwo-pole rectifier/charger output breaker.
bulletTwo-pole battery breaker.

High Voltage Shutdown (HVS)
Protects against overcharging should the rectifier/charger malfunction. Activates if output voltage exceeds a factory adjusted value. After shutdown, the rectifier/charger will start again after battery voltage drops below nominal.
