Access Power supply DC12V 8A with 1-15s time delay

Model No.: S4A-12V8A

What is Access Power supply?

These power supplies centralize the power sources of access control equipment. 

They include two supervision relays that can be used to integrate with other systems such as an alarm control panel.

NC terminal and GND terminal: power-off door type electric lock control port, normal output DC12V voltage, NC is positive, power off for 0~10 seconds after triggering.(NC and GND output 17V when no load)

NO terminal and GND terminal: power-on door type electric lock control port, no output in normal state, NO is positive after triggering, and output DC12V voltage for 0~10 seconds

PUSH terminal and GND terminal: input terminal of door open button, can input switch control quantity

+12V terminal and GND terminal: can provide DC12V power supply for the device.

CONTROL electrical signal input terminal: can input DC12V electrical signal control. (Note: The positive pole of the input electrical signal is connected to CONTROL+, and the negative pole of the electrical signal is connected to CONTROL-)
