100W Single Output with Battery Charger (UPS Function)

DRC-100 series

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.

A : 12V

B : 24V

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 protection is activated.

Function

Description

Output of alarm

Low or short

The signal is "Low" when the power supply turns ON.

AC OK

High or open (External applied voltage 30V max.)

Low or short

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.

Battery Low

High or open (External applied voltage 30V max.)

Table 2.1 Explanation of alarm signal

AC OK (Battery low)

External voltage sorece (V) and resistor (R)

(The max. Sink is 1A and 30V)
