24 Volt Central Battery Systems for Smaller Premises

Powerseal central battery systems are designed to provide a 24 Volt supply to emergency lighting in small premises. All models are housed in a sturdy steel cabinet suitable for wall mounting and are supplied with a quality, 5 year life, maintenance-free sealed lead acid battery.

Non-maintained units provide a 24 Volt DC supply when mains fail.

Maintained units provide a 24 Volt AC when mains are healthy and 24 Volts DC from the battery when mains fail. The maintained output can be switched on maintained units.

A range of optional extras can be specified where additional functions are required.
