Advanced MXP-651/D 5.0A 24V EN54-4 PSE & Battery Charger - Deep (up to 2x 24Ah or 38Ah batteries)

The Advanced MXP-651/D is a 5.0A, 24V EN 54-4 power supply and battery charger in a deep enclosure with space for two 24Ah or 38Ah batteries. It can be used with any fire alarm system, including automatic opening vent (AOV) systems, and complements the Advanced MxPro 5 range.

Key features

• High-efficiency switch-mode power supply with intelligent battery charging
• Two independently monitored 27.6V DC outputs
• Mains and battery monitoring, with a volt-free fault output
• Exterior status LEDs for quick diagnostics
• Load sharing, supporting rapid charging or brief high-current peak loads
• No output interruption during automatic switchover between mains and battery
• Deep discharge protection disconnects the battery from the load when the output falls below 21.6V
• Self-resetting battery fuse protection
• Suitable for any 24V fire alarm installation specifying EN 54-4 power supplies (e.g. BS 5839), and for EN 12101 smoke control and AOV systems
• Certified by VdS to EN 54-4 and by AFNOR to EN 12101-10
