Stand-Alone Power Supply 2.5 Amp

2.5 Amp PSU designed to meet the requirements of EN54-4.

This range of PSUs includes all of the necessary monitoring and standby capability demanded by EN54-4. Each unit comes within the same size steel enclosure for ease of use, offering 2.5A or 5A alarm capability.

Each model has an input that may be used to disable the battery charging in a fire condition so that the full output is provided to the driven equipment. This maximises the output current capability whilst allowing full monitoring and protection of the outputs. This flexibility means that the power supply to offer appropriate standby (e.g. 24 or 72 hours) for the system may be selected.
