GB/T 26697-2011 Low-frequency square wave electronic ballasts for metal halide lamps
Basic Information
Scope
This standard provides the performance requirements and operating characteristics of low-frequency square-wave electronic ballasts for metal halide lamps. The operating power frequency of the electronic ballast is 50 Hz, and the maximum power voltage is 250 V. The output frequency of the electronic ballast can be set to frequencies other than 50 Hz. The operating current frequency of the lamps covered by this standard ranges from 50 Hz to 400 Hz (applicable to certain individual frequency ranges), and the metal halide lamps used with them should comply with the requirements of GB/T 18661 and IEC 61167. A square-wave electronic ballast is defined as an electronic ballast whose lamp operating current waveform is essentially a square wave and meets the rise/fall time requirements specified in clause 5.4.4.1 of this standard.
