The HE-PSU(2.5A) is a fully EN54-4 certified power supply designed to deliver a stable, fully regulated 24 V output for fire alarm system applications, even under varying power conditions. Its advanced regulation technology ensures a consistent 24 V supply is maintained when operating from standby batteries, providing reliable and optimum power to all connected 24 V devices.
An integrated microcontroller provides intelligent battery management, using temperature-compensated charging algorithms to optimise charging for different battery types. This helps maximise battery performance, extend battery life, and keep the batteries in optimal condition.
Housed in a robust, key-lockable enclosure, the HE-PSU(2.5A) is suitable for a wide range of fire alarm applications. It can be used with the FIRElink range of air-sampling detectors, as well as Smart-Fix CHQ Modules that require an auxiliary 24 V DC power supply.
