Conditions of use: can be widely used in public lighting control, the normal conditions of use:

(1) Ambient temperature: -20-45 ℃

(2) Altitude: 2000 meters

(3) relative humidity: <95%

(4) gas, steam, chemical precipitation, dust, dirt and other explosive and corrosive media which have no obvious influence on voltage-regulating insulation

(5) silent place in the installation of vibration or bumps.

Soft start: reduce the impact of instantaneous current appliances to protect the lamp;

Regulator: the input voltage between 190-206V, the output voltage can be maintained at 220 ± 3V range;

Input protection: input voltage range, to prevent the voltage shock, so as to better protect the lamps and reduce operating costs;

Over-current protection: the main circuit current exceeds the rated current will sound and light alarm, more than 10% of the rated current alarm and jump bypass operation.
