DBSL-500A Primary Current Injection Test Set

Product Introduction

DBSL-500A Primary Current Injection Test Set, is mainly used for testing current transformer, motor protector, air switch, switch cabinet, circuit breaker, protection screen and etc.

Product Features

l  PVC panel, simple and neat.

l  With low power, big capacity auto transformer regulator and converter inside.

l  Zero start function to prevent the test objects from damage caused by high current impulse. The equipment only can be started from zero.

l  Impulse selection function. The required current can be output directly without zero protection function when making quick-break testing for circuit breaker.

l  Accurate measurement. LCD digital indicator to display output current and voltage. The resolution of output current is 1A and output voltage is 1V.

l  Portable design, suitable for on-site testing.

l  Damping design, to ensure reliable transportation.

l  The current range can be switched, easy to read.

l  Engineering plastics box, dust-proof and waterproof, IP67 class.

l  With wedge-shape air flue to improve heat-dissipation ability.

l  Directly display primary current and secondary current, convenient for CT/PT turn ratios calibration test. (Optional)
