Suggested Application
CN3 Pin2(Pin4)
External voltage source (V)
and resistor (R)
(The max. Sink is 1A and 30V)
1.Backup connection for AC interruption
2.Alarm signal for AC OK and Battery Low
(1) Please refer to the Fig1.1 for suggested connection.
(1) Alarm signal is sent out through " AC OK " & " Battery Low " pins.(relay contact type)
(2) An external voltage source is required for this function. The maximum applied voltage is 30V and the maximum sink current is 1A.
(3) Table2.1 explains the alarm function built in the power supply

The power supply charges the battery and provides energy to the load at the same time when the AC main is OK.
The battery starts to supply power to the load when the AC mains fails.
