NEMA - ANSI C82.17
Lamp Ballasts - High Frequency (HF) Electronic Ballasts for Metal Halide Lamps
|Publication Date:||1 January 2017|
This standard provides specifications for and operating characteristics of, high-frequency electronic ballasts for metal halide lamps. Electronic ballasts are devices that use semiconductors to control lamp starting and operation. The ballasts operate from multiple supply sources up to 600V maximum at a frequency of 60 hertz. This standard covers electronic ballasts with sinusoidal lamp operating current frequencies above 40 kHz.
