1.Back up 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 explain the alarm function built-in the power supply
(4) RL1 (AC OK)signal will go into hiccup mode when the overload protection is activating.
Output Derating
Suggested Application
The power supply charge the battery and provide energy to the load in the same time when the AC main is OK.
The battery start to supply power to the load when the AC main fails.

The signal is "Low" when the power supply
turns on
The signal turns to be "High" when the power
supply turns OFF
The signal is "Low" when the voltage of
battery is under A:11V, B:22V
The signal is "High" when the voltage of
battery is above A:11V, B:22V
