According to Double end fluorescent lamp of IEC 60081 (GB/T10682) and the single-ended fluorescent lamp of IEC60901 (GB/T17262), ANSI C78.81 and ANSI C82.3, DYJ Adjustable Reference Standard Ballast is used to test for 4w~85w fluorescent lamp and electronic ballast test. DYJ_adjustable reference ballast Specification: • Inductance: 0~1240Ω (adjustable) • Inductance Power Factor COSφ: 0.0...
The ballast (resistor ballast) is a device for limiting the flow of sunlight and generating instantaneous high pressure. Following is some difference between the electronic ballast and inductance ballast. 1. Inductance Ballast is an iron core inductance coil, the inductance characteristic is when the current changes in the coil, the magnetic flux changes, resulting in the induction electromotive, ...
