DDRJ-2000E three phase thermal relay tester is mainly used for thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, circuit breaker, protection screen check.
Three-phase thermal relay tester DDRJ-2000E 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.
It can be a long time 0-2000A current output
It can be synchronous test thermocouple, thermal relay, motor protector action time
The normally open and normally closed contact detection
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.
