Ballast Electronic Ballast lighting equipment accessories

DYJ Multifunction reference ballast ballast fluorescent electronic ballast lighting equipment accessories Product Description 01 DYJ multifunction benchmark test fluorescent lamp ballasts, high-pressure mercury, sodium, metal halide and other optical parameters of the gas discharge lamp is measured gas discharge lamps must operate in standard conditions, the most important requirement is matched with a reference ballast to ballast, otherwise, if the same work at different lamp ballasts, will have different Optical properties. Technical parameters suitable for fluorescent lamps, high pressure mercury lamp, sodium, metal halide discharge lamp optical parameters of the test. A variety of reference ballast for the election, when the measuring optical parameters of the gas discharge lamp, the lamp shall be measured with reference ballast ballast, in order to meet the standards for the measurement conditions: nominal frequency (50Hz or 60Hz); correction current. Measuring the target value: current and voltage ratio (tolerance ± 0.5%); power factor (tolerance ± 0.005). DYJ multi-purpose reference ballast main technical indicators: inductance: 0 ~ 1240Ω adjustable (50Hz when) inductive power factor COSφ: 0.075-0.120 adjustable impedance: 0-111Ω use adjustable current range: 0.150-0.670A (maximum allows current to 1A) are welcome to inquire come to see goods prices is easy to talk to your satisfaction is our pursuit Zhongshan Office:!!!!
