GDSL-BX-200 Primary Current Injection Test Set, is mainly used in calibration for current transformer, motor protector, air switch, switch cabinet, circuit breaker, protection screen and etc. 

• 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 choose 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)
