Alarm Signal for AC OK and Battery Low
Function
AC OK
Battery
Low
Notes:
Description
Alarm Output
The signal is low when the power
supply turns on
Low
(0.3 V max. at 30 mA)
The signal is high when the power
supply turns off
High/open
(external voltage < 50 V)
The signal is low when the voltage of
the battery is below:
12 V (PSF-75-A), 22 V (PSF-75-C)
Low
(0.3 V max. at 30 mA)
The signal is high when the voltage of
the battery is above:
12 V (PSF-75-A), 22 V (PSF-75-C)
High/open
(external voltage < 50 V)
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.
