4 / 5 page 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. 60W Single Output with Battery Charger (UPS Function) D R C - 6 0 series File Name:DRC-60-SPEC 2014-10-22 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 V- V+ Bat- Bat+ Load A : 12V B : 24V Battery + + - - Fig 1.1 Suggested system connection External voltage sorece (V) and resistor (R) (The max. Sink is 1A and 30V) AC OK (Battery low) Fig 2.2 Internal circuit of AC OK (Battery Low), via relay contact Function Output of alarm Low or short Low or short High or open (External applied voltage 30V max.) High or open (External applied voltage 30V max.) Description The signal is "Low" when the power supply turns ON. 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. The signal turns to be "High" when the power supply turns OFF. AC OK Battery Low Table 2.1 Explanation of alarm signal (4) AC OK signal (RL1,referring to Block Diagram) will go into hiccup mode when the overload protecton is activated. R V + DC OK +V ADJ |
