Product Name:  FA9-139A Security Unit and Auxiliary


Features

 


·      There is an additional heavy-current touching grounding system, which makes it safer and more reliable.

·      A variety of PTC and discharging tubes can be installed as per users’ requirements.

·      In the process of jumper wiring and multiplexing, there is no need to unplug the unit.

·      Contact pins in a and b input and output lines are gold-coated.

·      Plastic parts are made of high temperature resistant materials.

·      In the event of a failure, Light Emitting Diode (LED) gives red light as an alarming signal.

 


Main Performance Indicators

 

·      Contact resistance: contact resistance between terminal piece and protector is 7mΩ

·      Overvoltage protection performance: DC breakdown voltage: Udc = 225 ±35V; pulse breakdown voltage: Umax ≤800V (at the time when the rate of voltage rise is 1000V/µ s).

·      Failure protection (FS) function: when the discharging tube discharges current up to 2.5Ar.m.s, Line a or Line b in the discharge circuit will be grounding and an alarm will be given within 15s.

·      Plastic parts’ flame retardant property: it complies with the provisions of GB/T5169.7.
