1000w hps ballast for high pressure sodium lamp. Normal end of life indication is on/off cycling, since the aging lamp requires a higher voltage for operation than the ballast can supply. This cycling sequence is normal, but not desirable, since the cycling can damage or destroy the starting circuit and/or ballast.

Thus, you should check a cycling HPS fixture without delay. Other conditions that cause cycling include: a loose electrical connection, faulty internal electrical connection to the lamp or at an outdoor installation, and severe fixture vibration, causing lamp voltage to rise above operating limits.

1000w hps ballast Wiring Diagrams
Ballast Wiring Diagrams for HID ballast kits including Metal Halide and High Pressure Sodium Lighting ballasts. Most magnetic ballastHID are multi-tap, meaning they can be connected to several different voltages.

Here we display wiring diagrams for metal halide (probe start), metal halide (pulse start) and 1000w hps ballast kits. Most magnetic HID ballasts are multi-tap, meaning they can be connected to several different voltages. Here we display wiring diagrams for metal halide (probe start), metal halide (pulse start) and high pressure sodium HID ballast kits.

Rapid-start (RS) systems. To measure the starting voltage of an RS ballast, connect a voltmeter between the highest reading Red lead and Blue lead with the lamp removed. (in the original article). Consider the following example: For an F 40 T12 two-lamp ballast, the minimum starting voltage is 256V.

The minimum starting voltage for F96T12HO two lamp ballast is 466V. For a F96T12VHO ballast, it’s 470V. All numbers are for minimum ambient temperature of 50DegrF. You should find these open circuit voltages on the Light ballast’s label.
