Technical parameters
I. Application and characteristics
HSJB-2000 single-phase relay protection tester is another new relay protection test equipment developed by our company in 2011. The weight of the equipment is only 12 kg without changing the main body. It adopts stainless steel or plastic aluminum chassis, which is beautiful and firm with good shock absorption performance. It adopts double carbon brush voltage regulator (i.e. double-sided voltage regulator). The large knob adjusts the AC and DC voltage and current with heavier load, and the small knob adjusts the AC and DC voltage and current with lighter load. Two channels can be output simultaneously. It adopts 0.5-level digital meter and high-precision sensor for accurate measurement. It adopts six-digit electric stopwatch to meet the time measurement. It is a good tool for relay protection workers to work outside.
