Alarm Signal for AC OK and Battery Low
Function
AC OK
Description
The signal is low when the power
supply turns on
The signal is high when the power
supply turns off
The signal is low when the voltage of
the battery is below:
12 V (PSF-155-A), 22 V (PSF-155-C)
The signal is high when the voltage of
the battery is above:
12 V (PSF-155-A), 22 V (PSF-155-C)
Alarm Output
Low
(0.3 V max. at 30 mA)
High/open
(external voltage < 50 V)
Low
(0.3 V max. at 30 mA)
High/open
(external voltage < 50 V)
Battery
Low
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.
