Motor protector tester is collected throughout the user feedback information and years of practice experience to develop and become a new generation of measuring instrument, mainly used for various thermal relay and motor protection device for the tuning and testing. Because of its reasonable design, convenient operation and high output power, it is widely used in electric power system, railway, petrochemical, metallurgy and mining and other enterprises.

Suitable for single phase, three-phase thermal relay and all kinds of active or passive motor protector of over-voltage, over current, lack of phase, not

The action time of the action current and the rated current of the current relay can be tested.

It may be a long time to output 0 ~ 50A or 0 ~ 500A current

It can be synchronous test of thermal relay, circuit breaker, motor protector action time

The normally open and normally closed contact automatic identification

You can also connect a plurality of check, improve work efficiency

- equipped with color LCD display, high reliability, long service life, good seismic performance

Power input: 380/220V 50Hz AC three-phase four wire

Rated power: 1*3 3KVA only 3 phase 2KVA a set

Instrument grade: 0.5

Output current: A phase: B 0-500A phase: C 0-500A phase: 0-500A

Output voltage: A phase: B 0-220V phase: C 0-220V phase: 0-220V

AB phase: BC 0-380V phase: CA 0-380V phase: 0-380V

AB phase: BC 0-660V phase: CA 0-660V phase: 0-660V

The newly added function is mainly based on the original SDRJ-500S to increase the voltage, while the current output function, and the voltage current monitoring, no need to be converted. Increased the 0-380V output file is adjusted more accurately.

According to the requirements of the design 0-10000A. Since 2000, our company has designed and produced, SDRJ-500III, SDRJ-500E, SDRJ-500S, SDRJ-500XP, SDRJ-500EP, SDRJ-500SH series thermal relay, motor protector tester. Good things please pay attention.
