● Digital control, high anti reference ability.
● Adapts autotransformer regulator which with low power consumption and large capacitance.
● Converter has high permeability core.
● Quick connects, lock design, have good current capability.
● PVC panel.
● Build-in quick plug with high safety.
● Current range can be changed, easy to read.
● Engineering?plastics box, IP67 dustproof and waterproof.
● Portable design is suitable for on-site testing.
● Zero start function to prevent the test objects from damage caused by high current impulsing. The equipment only can be started at zero.
● Impulse choosing function: The current value can be outputted directly without zero protection function when the equipment is under the testing for circuit breaker.
● 0-50A AC current can be outputted, suitable for over current quick break testing of secondary protection.
● Action time can be tested synchronously.
● More calibrations can be series connected at same time to improve working efficiency.
● To display the testing value of primary current, secondary current directly, convenient for CT/PT turn ratios calibration test. (Optional)
