Uninterruptible Power Supply PS12-2.5-12 for Continuous Operation of Fire Safety Systems

uninterruptible power supply units of PS12 and PS24 series (hereinafter - UPS) are designed for uninterruptible power supply of fire automation equipment with voltage of 12 V and 24 V DC. PSEs provide transmission of messages about their current state to the addressable fire alarm and control device "Vesta 01F" via the addressable communication line of the device (hereinafter referred to as "AC"). The UPS provide output of the generalised signal "Fault" by means of changing the state of the galvanically isolated optorelay "Fault". ("Fault"). The UPS provide automatic charging of the connected battery (hereinafter referred to as the battery) with automatic control of the battery status and availability and disconnection of the battery from the load in case of severe discharge. UPS provide protection against short-circuit and current overload at the output with automatic restoration of the output voltage after removal of the short circuit.
