Three-phase current generator company self-developed developed a testing device, which combines the advantages of similar products at home and abroad in a body, and adopts the technology of numerical control, anti-interference ability strong, and a generation of up flow is compared, due to the low power consumption and large capacity self coupling voltage and high permeability iron core made of the converter has the advantages of high output power, small volume, light weight, etc.. Mainly used for thermal relay, motor protector, contactors, breaker device, air switch, switch cabinet, circuit breaker protective screen calibration and ratio, time, over current, the current relay and switch off speed, transmission test setting check.

PVC panel with beautiful appearance

Direct current, easy to test observation and record.

Measurement accuracy of 0.2

Power, small size, with a strong load capacity

Small size, light weight, the volume of only 30% to 70% of similar products, very convenient to carry.
