Number Electronic Ballast, our proprietary brand products:

NB-HPS/MH250W

1.Independently developed application: specific control software unit to help setting up a simple circuit with stable performance.

2.Full protection systems: open loop protection, short loop protection, hot lamp protection.

3.High power factor, reduce cost of initial installation; high efficiency, result in remarkable energy-saving purpose.

4.Startup at low input voltage and current, bear wide range of fluctuation of voltage and current, output constant voltage and current, able to prolong lamp life and improve quality of illumination(no flashing, no acoustic resonance), and furthermore, accept ordinary related equipments, such as wires and transformers.

5.Low total harmonic distortion, low impact on power network and other related machines

6.Low rate of temperature rising while working, wide range of operating temperature: -30 +55 centigrade.

7.Long line (max. 15m) driven, the lamp and the ballast can be installed around 15m away, easy for installation and maintenance.

8.Light weight, low noise.
