Application range of DDRJ-500E three phase thermal relay 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.
Application of 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
In 2013 1, the original equipment upgrade to 0.001-99999.999S electric stopwatch, current meter upgrade to 5 digit display 0.2
2, has pushed SDRJ-500SH, SDRJ-500T, SDRJ-500VA, SDRJ-500EP new products, for the country's only one for the thermal relay testing equipment manufacturers launched products!
2014 new instruments all changed to six and a half meters, LCD liquid crystal display, the background is yellow, thick black body, is the equipment in the sun is also shown very clear!
3, in the second half of 2014, using the latest German technology of constant current, IGBT module, PWMN technology to develop a new generation of high current generator, three-phase thermal relay tester (R & D)
Current according to demand 0-50000A, according to the function of production.
2, the main technical indicators
