Product Details

Introduction:

GDZC Transformer DC winding resistance tester uses Constant current source to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and so on.

GDZC Transformer DC winding resistance tester has functions of self test, data processing, discharge rapidly, result print and so on.

Functions:

A new switching power supply technology makes output current more stable and power larger than before.

The tester has an advanced signal process circuit which has a good performance at anti-noise. Test data is precise and stable.

The tester has protections to prevent circuit over-current, circuit over-voltage, wrong operation, discharge and so on.
