First, use and characteristics

JDS-2000Type relay protection test box is developed in 2000, another new relay protection test equipment, the device in the subject of the same circumstances, the weight of only 10 kg, the use of stainless steel or plastic aluminum chassis, beautiful solid, shock Good performance. Using double-carbon brush regulator (that is, double-sided regulator), the big knob to adjust the load of heavy alternating current and voltage, current, small knob to adjust the load of light alternating DC voltage, current, Output. Using 0.5 digital table, high-precision sensor, accurate measurement, the use of six-digit electric stopwatch, to meet the time measurement, in fact, relay protection staff work out a good tool.

Second, the main technical characteristics:

1Input power: AC220V ±10% 50Hz

2Nominal capacity: 1KVA (can be increased or decreased according to requirements)

3. Output:
