20182424N: 18Ah 12V Valve Regulated Lead Acid
Intelligent Battery Recharge Time:
< 24 hours to 80% - A heavily discharged battery having a
terminal voltage > 9.0V will attempt to be charged. If battery fails
to accept charge in 24 hours it will fail the active load test.
Testing:
Battery not Present: <9.0V battery voltage
Low battery voltage: <11.6V (no mains present)
Active load test at full rated output current
Protection:
Reverse battery connection protection
Overvoltage protection - Trips at 125% of rated O/P voltage
Deep discharge protection - Battery disconnect at 10.5V battery
terminal voltage
Quiescent Current:
64mA when running on battery - less than 1mA after deep
discharge protection.
Battery Cold Start (BCS)
Momentarily link BCS pins together to connect battery to load if
PSU commissioned without any mains
