Notes

Notes

Maximum current drain from battery by PSU when inactive 22 mA

1. With AC in, unit provides power to the load and to charge the

battery. The DC OK signal acts by sensing a voltage on +V and

holds the relay closed.

2. With loss of AC in, battery voltage is present on +V. DC OK

signal holds the relay closed. Battery supplies power to the load.

3. As the battery discharges, its voltage falls. When this falls below

the level shown in the table below the DC OK signal switches off

to allow the relay to open to disconnect and protect the battery.

1. Suffix # indicates standby version.

2. Not UL1310 approved.
