How to connect the ballast of metal halide lamp

1, 220V AC power line (red line L, blue line N, yellow line/green line yellow-green line ground line E).

2. Inductive ballast (any line of 220V power line L and capacitor is terminated at the edge, and trigger B is connected at the inner end).

3. Power compensation capacitor (any one of the two wires is connected in parallel with the 220V live wire, and the other one is connected to the zero line n).

4.CD-7 electronic trigger (three wires are B- connected to the ballast, LP- connected to any light bulb and N- connected to the zero line).

5. Lamp holder (one of the two wires is connected to the trigger LP and the other is connected to the neutral line n).

Precautions:

What if the metal halide lamp doesn't work?

(1) Check whether the lamps and lanterns have input electricity, and measure whether the input terminal voltage of the power supply is normal with a multimeter.

⑵ Check the bulb for deformation, perforation and other abnormal phenomena.

(3) Remove the bulb and check whether the contact piece in the lamp holder is broken or ablated, and whether the contact between the bulb and the lamp holder is good.

(4) Carefully observe whether the terminal board and ballast coil in lamps or ballasts have ablation marks. Whether the capacitance and trigger are abnormal.
