Three-loop DC resistance tester

Transformer DC resistance measurement, is the manufacturer of electrical equipment and electrical hair, the electricity sector in the transformer factory inspection, handover testing, preventive testing work will test items, can enhance product quality and prevention of electrical accidents. Our company has developed a three-loop DC resistance tester, from the high-power switching power supply circuit, precision small signal measurement circuit, protection circuits, high-speed MCU control circuit etc., equipped for instrument self-test, signal measurement, data processing, rapid discharge, print results and so on. Products have multiple models for users to choose, has been widely used in electric power and related sectors, praised by users.

1, the main features

1. Using the new switching power supply technology, the output current ripple, good stability, high power;

2. Offers a variety of measurements, example: three-loop measurement, three-phase automatic, manual and conventional three-phase single-phase measurement.

3. The use of advanced signal measurement circuit, low noise, strong anti-interference, true and reliable test data;

4. Has a complete over-current, over voltage, misuse, discharge protection, after many, many experiments under the conditions that: clip out the testing process, a sudden power failure, equipment is not damaged;

5. Compact, small size, light weight, more suitable for field use;

6. Output current to provide more stalls, so that a wider measuring range;

7. Large character LCD screen, various functions prompt, convenient operation.
