The test instrument of three-phase thermal relay is suitable for single, three-phase thermal relay and a variety of active and passive motor protection action current and time for testing automatic identification of normally open and normally closed contact automatic identification.

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

It can balance three-phase current output, with fine function

It can be synchronous test thermocouple, thermal relay, motor protector action time

The normally open and normally closed contact automatic identification

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

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

Instrument grade: 0.2

Output current: 3 * 1000A

Measurement: when the measuring range: 0 001S---999999.999S, precision: 0 001S

Voltage and current six - half liquid crystal display, the display accuracy is higher, the experimental result is more accurate (domestic only)

128*64 dot matrix LCD display, the display data is more intuitive, more efficient reading (domestic only)

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.
