ZSP series according EN 54-4/A2

Brochure ZSP.pdf

The power supply ZSP135-DR is dedicated to work in systems of fire protection signaling and automation.
It is a source of guaranteed 24V voltage.
It is manufactured as a wall box with a lock. It has a space inside to mount two batteries.
The controller protects the internal battery bank against too low discharge by means of the built-in
