The Advanced MXS-651 is the spare 24V 5A EN 54-4 power supply and battery charger, supplied without an enclosure. Advanced lists it in the same range as the MXP-651 5.0A boxed power supply units. It suits fire alarm systems that need a 24V EN 54-4 supply, as well as EN 12101 and AOV systems.
It is a high-efficiency switch-mode unit with intelligent battery charging, mains and battery monitoring and two independent volt-free outputs. Deep discharge protection disconnects the battery if there is a long mains failure, and LEDs give quick status diagnostics.
