Replacement HF Ballast and Emergency Kit

Specifically designed to replace existing control gear
Quick and easy installation, only 3 additional wires to be connected (unswitched, live & LED)
High efficiency electronic battery charging with deep discharge battery protection
Suitable for use with linear T8 fluorescent tubes
Operating frequency > 30kHz
The 18W unit has multi way ballast for 3 to 4 tubes, only 1 of which is an emergency
The 2´36W and 2´58W units run both tubes in normal mode, but under emergency conditions runs in single tube operation only
Supplied with combined ballast and emergency module, battery pack with holder and remote mounting LED
Battery packs used comprise high temperature NiCd Accu D Cells in dedicated packs for high temperature operation


Nominal tube diameter - T5=16mm, T8=26mm, T12=38mm

Conversion Kits

Charger/inverter modules for converting fluorescent luminaires into emergency lighting units.,The module and battery packs fit inside most modern fluorescent batten fittings. For luminaires that have limited internal dimensions or that have internal temperatures above 50°C, remote mounting boxes are also available. The remote box is also suitable for converting double luminaires into emergency units, however only 1 tube will operate under emergency conditions. Two live supplies are required for standard operation, one switched, one unswitched. Failure of the unswitched supply operates the changeover circuit bringing on the battery supply. A red LED is supplied with the module for fitting into either the luminaire or remote box, to indicate a healthy battery charging state. The nickel-cadmium battery packs are protected against deep discharge.
