Scope of application of DDRJ-500S motor protector tester:
1, suitable for various types of low-voltage motor protection, thermal relay test.
2. Test whether the motor protector is effectively protected in the running state.
3, applicable to the test room for low-voltage motor protection device test.
4, applicable to the production of motor manufacturers for product quality verification, testing and commissioning.
5, applicable to the research and development of universities and research institutions, testing, teaching.
 
1, suitable for single-phase and three-phase thermal relay and a variety of active or passive protector for motor over voltage, over flow, lack of phase, unbalanced, locked rotor and the test of time, can also test the relay current action current and rated current action time.
It may be a long time to output 0 ~ 50A or 0 ~ 500A current
It can balance three-phase current output, with fine function
The three-phase voltage can be balanced output, has the fine function
We can test the thermocouple or synchronous thermal relay action time
The normally open and normally closed contact automatic identification
You can also connect a plurality of check, improve work efficiency

Three-phase thermal relay selection table
In 2013 1, the original equipment upgrade to 0.001-99999.999S electric stopwatch, current meter upgrade to 5 digit display 0.2
2, SDRJ-500T, SDRJ-500VA, SDRJ-500SH, SDRJ-500EP for the launch of new products, the only one for the test instrument of thermal relay manufacturers!
In 2014 the new instrument all changed to six and a half meter, LCD liquid crystal display, background yellow, thick bold, equipment is also shown in the sun is very clear!
3, the second half of 2014, the new German constant current technology, IGBT module, PWMN technology is the development of a new generation of high current generator three-phase thermal relay tester (R & D)
According to the current demand of 0-50000A, according to the production function.
