What does a capacitor do in a HPS light?

What does a capacitor do in a HPS light?

Capacitors are another type of isolation technique that helps to regulate current and keep the arc stable inside of the lamp. Capacitors also help balance the circuit out because it is a capacitive component, which acts inverse to the inductive element of the ballast.

What is 1000w ballast?

1000w Ballasts are capable of illuminating up to 1.5m2. SPECIFICATIONS: Operates Metal Halide and High-Pressure Sodium bulbs. Runs 600w, 750w, 1000w bulbs at standard operation.

How do you test a ballast capacitor?

The proper test procedure is as follows: – Disconnect the Metal Halide, High Pressure Sodium or Pulse Start capacitor from the circuit and discharge it by shorting the terminals or wires together. – If the meter indicates a very low resistance then gradually increases, the capacitor does not require replacement.

Why does a light need a capacitor?

In a fluorescent light, the capacitor improves the power factor and also helps to absorb the high starting voltage, preventing spikes on the supply line.

How do you ground a ballast?

If the ballast doesn’t have a ground wire or terminal the ballast is just grounded to the fixture housing by it’s mounting screws. The ground wire on the cord usually attaches to a designated (green) screw on the fixture frame.

What is the difference between magnetic and digital ballast?

Digital ballasts generally have the option to adjust the wattage they are running at. It means you can use either a HPS or MH lamp with the same ballast, and even change between 400w lamp and 600w lamp for example. With a magnetic ballast, you would have to buy dedicated ballasts for each wattage of lamp.

Is a ballast a capacitor?

Ballasts vary greatly in complexity. They may be as simple as a resistor, inductor, or capacitor (or a combination of these) wired in series with the lamp; or as complex as the electronic ballasts used in compact fluorescent lamps (CFLs) and high-intensity discharge lamps (HID lamps).
