Product Description

Product Description

HCT System AC Constant Current Source

Power Feature

The HCT series AC constant current source is a high-precision current-stabilizing AC power supply featuring low harmonic distortion. It can maintain a constant output current even when the external grid power fluctuates or the impedance characteristics of the load change. It is applicable to products and scenarios requiring tests and applications based on the thermal effect of specific currents, such as tests for circuit breakers, fuses, thermal relays, magnetic starters, coils and other components.

1. High current stabilization accuracy to ensure constant output current.
2.Supports automatic testing for different current levels and cyclic test operations.
3.Capable of driving resistive, inductive and capacitive loads, complying with power supply requirements for low-voltage electrical appliance testing.
4.Delivers constant output current with a pure sine wave output waveform, serving as test equipment for overcurrent experiments.
5.Automatically switches between constant current and constant voltage modes, integrating control and protection functions for comprehensive performance.
