C. Batteries
1) Battery Type: Sealed, Valve Regulated Lead Acid cells
2) Protection Time:
Each standard matching battery pack shall provide
the minimum run-time:
- 5 minutes back-up time @ 50 kVA
3) DC Voltage Range:
UPS Capacity 50 kVA
Nominal Voltage 288 VDC
Alarms Voltage(V low) 252 VDC
Shutdown Voltage (V min) 216 VDC
4) Ripple Voltage: 2% RMS maximum
D. Environmental
1) Efficiency: 89% (AC/AC); 90.5% (DC/AC)
2) Operating Temperature: UPS: 32 to 104° F (0 to 40° C)
Battery: 68 to 77° F (20 to 25° C)
3) Storage Temperature: UPS: -4 to 140° F (-20 to 60° C)
Battery: prolonged storage above 104° F
(40° C) causes rapid battery degradation
