10V1000A AC constant current source

FJH AC constant current source is a wideband, high-precision AC stable current power supply with fast response speed, high constant current accuracy, stable and reliable continuous operation, and suitable for various types of loads (resistive, inductive, capacitive). This power supply is mainly used to detect protective switches such as thermal relays, circuit breakers, magnetic starters, and low-voltage electrical appliances that require setting rated current, operating current, short-circuit protection current, and other thermal effect tests for verification and testing. The output current of this power supply can be adjusted from zero to the rated value, and it allows open circuit operation of the load during use.

The AC constant current source adopts SPWM high-frequency pulse width modulation, and the IGBT module is inverted and isolated by an isolation transformer for output. It works stably and reliably, with high output current accuracy, low current waveform distortion, no environmental pollution or noise during operation, and can completely overcome current changes caused by grid voltage fluctuations, circuit resistance changes, and product internal resistance changes. It is not affected by human factors, has a good human-machine interface, can be used in conjunction with advanced production line systems, and can also be used independently. Widely used in aerospace, national defense, military industry, quality inspection institutes, low-voltage electrical industry, enterprises and institutions, and other places.
