Overview
The Model 738 DC Power
Supply with Battery Back-Up provides a filtered and regulated source of
54 volts DC with a maximum output current of 3 amperes. The input
voltage range is 110 to 240 volts, 50/60 hertz. Rechargeable batteries
contained within the Model 738 provide output back-up capability in the
event of an AC input voltage interruption. Under battery operation, the
Model 738 will continue to supply a 3 ampere DC output for up to
nominally two hours. For output loads of less than 3 amperes the battery
operating time will substantially increase. The unit is completely
self-contained in a compact enclosure. Mounting kits, available
separately, allow the unit to be wall or rack mounted. The Model 738 is
Underwriters Laboratories, Inc. LISTED under their CUL-60950 ITE
category.
