PRIMUS EVG series emergency lighting kits for mounting in luminaires equipped with 4-pin, 6-36W fluorescent light sources.
Adapted to work with magnetic (KVG) and electronic (EVG) ballasts.
They detect the loss of normal power supply, i.e. 230V/50Hz, and using the current stored in the batteries, they start to generate high-frequency voltage necessary to power fluorescent lamps.
3h battery: 3.6V Ni-Cd HT 4Ah
Working temperature: 5°C ~ 55°C
