Power supply: 220-240VAC/50-60Hz Fluorescent power: 8 - 80W (depending on model) Electronic processor charger Type of lighting sources: T5 Ambient temperature: 0 - +55°C Operation temperature: 0 - +70°C Used batteries: maintenance-free high temperature Ni-Mh HT or Ni-Cd HT Battery set power: power 3,6V, 4,8V, and 6,0V and capacity of 1,5 - 4,0Ah (depending on model) Less heat loss what allows mounting in tight luminaries Maximum Power of battery discharge:f the normal power supplying and efficiency of battery charging. Control of the minimum power of battery discharging. Optimal conditions for battery power supplying (according to battery type) Permanent anti-corrosion transformer. Long period of luminary operations owing to the heating system of electrodes.
