AC-DC Battery Backed Power Supply
Block Diagram and Alarm Signals (GB & LB versions)
Alarm Signals for AC OK and Battery Low
• These signals are volt free relay contacts and therefore an external voltage source is required
• The maximum applied external voltage is 30V and the maximum sink current is 1A
Function Description Output of alarm
AC OK
Signal is ‘LOW’ when the power supply turns on. Low or short
Signal is ‘HIGH’ when the power supply turns off High or open (externally applied voltage 1A max.)
BAT. LOW
Signal is ‘LOW’ when battery voltage is under G:12V, L:22V Low or short
Signal is ‘HIGH’ when battery voltage is above G:12V, L:22V High or open (externally applied voltage 1A max.)
Internal circuit of AC OK (Battery Low)
External voltage source (V) and resistor (R).
Maximum applied voltage is 30V and maximum sink current is 1A
