12 V (PSF-75-A), 22 V (PSF-75-C)

(0.3 V max. at 30 mA) The signal is high when the voltage of the battery is above: (external voltage < 50 V) Notes: 1. Alarm signal is sent out through “AC OK” and “Battery Low” pins. 2. An external voltage source is required for this function. The maximum applied voltage is 50 V and the maximum sink current is 30 mA.

PSF-75-B & PSF-75-D Alarm Signal for AC OK and Battery Low Internal Circuit of AC OK and Battery Low Function Description Alarm Output AC OK The signal is low when the power supply turns on Low or short The signal is high when the power supply turns off High/open (external voltage < 30 V) Battery Low The signal is low when the voltage of the battery is below:

12 V (PSF-75-B), 22 V (PSF-75-D)

The signal is high when the voltage of the battery is above: (external voltage < 30 V) Notes: 1. Alarm signal is sent out through “AC OK” and “Battery Low” pins (relay contact type). 2. An external voltage source is required for this function. The maximum applied voltage is 30 V and the maximum sink current is 1 A.
