The electric transformer, inverter module, 1mm green charge healthy indicator and batteries are housed within a sheet steel enclosure with a hinged lid to aid access to the wiring connection points and fused terminals. Using the key hole slots, the pack can be fixed directly to solid surfaces to ensure a neat installation is achieved.

The pack is for the use of 24V lamps supplied at 100% power output. Supplied as Non Maintained as standard but can be used in conjunction with the existing mains transformer to form a maintained circuit.
