60W Single Output with Battery Charger (UPS Function)
Suggested Application
1.Backup connection for AC interruption
(1) Please refer to Fig1.1 for suggested connection.
The power supply charges the battery and provides energy to the load at the same time when AC mains is OK.
The battery starts to supply power to the load when AC mains fails.

2.Alarm signal for AC OK and battery low
(1) Alarm Signal is sent out through " AC OK " & " Battery Low " pins via relay contact.
(2) An external voltage source is required for this function. The maximum applied voltage is 30V and the maximum sink current is 1A. Please refer to Fig 2.2.
(3) Table2.1 explains the alarm function built in the power supply
(4) AC OK signal (RL1,referring to Block Diagram) will go into hiccup mode when the overload protecton is activated.
Function
AC OK
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.
Battery Low
The signal is "High" when the voltage of battery is above A:11V, B:22V.
Table 2.1 Explanation of alarm signal
Description
The signal is "Low" when the power supply turns ON.
