MS Series Battery Support Systems
The battery support system for a single cabinet UMS installation (62.5kVA, 50kW) consists of 30 sealed, maintenance free, immobilized electrolyte, batteries installed in an open battery rack. The UMS system DC voltage regulator provides for automatic charging of the battery system to maintain the proper float voltage.
A battery disconnect center is located on the end of the battery rack.
Battery support time at full load (50kW) is approximately 15 minutes. The waveform quality at the end of the battery support time meets the requirements of MIL-STD 1399, section 300A, Types I, II and III power forms. On-Line, No-Risk Battery Test
This feature of the UMS system provides the ability to perform a battery test on command from the front panel or RS-232 serial port. Test results are displayed on the front panel and are available over the serial port as a part of the system diagnostics. A battery failure during the test will not cause the system to drop the load or distort the output waveform.
