NEMA C82.4
For Lamp Ballasts - Ballasts for High-Intensity-Discharge and Low-Pressure Sodium Lamps (Multiple-Supply Type)
Organization:
NEMA - National Electrical Manufacturers Association
Year: 2002
Abstract: This standard provides specifications for and operating characteristics of ballasts for mercury, metal-halide, high-pressure sodium (HPS), and low-pressure sodium (LPS) lamps. The ballasts operate from multiple-supply sources of 600 volts maximum at a frequency of 60 hertz. They may be designed for operation under either indoor or outdoor conditions.
The following types of ballasts are excluded from this standard:
(1) Ballasts consisting of resistance only
(2) Transformers for constant current (series) operation of mercury lamps (see American National Standard for Mercury Lamp Transformers - Constant Current (Series) Supply Type, ANSI C82.7-1983 (R1988)
(3) All ballasts that use semiconductors to control the lamp power.
The following types of ballasts are excluded from this standard:
(1) Ballasts consisting of resistance only
(2) Transformers for constant current (series) operation of mercury lamps (see American National Standard for Mercury Lamp Transformers - Constant Current (Series) Supply Type, ANSI C82.7-1983 (R1988)
