Product Overview：

HCT series is a stable current source with wide frequency spectrum, high accuracy, low harmonic and 

distortion. The constant current source is an AC power source that can keep the output current constant

 when the external power supply fluctuates or the impedance characteristics of the power supply are 

changed. The power supply is mainly used in products and places where specific current thermal effects 

are applied and tested. For example, circuit breakers, fuses, thermal relays, magnetic starters, coils, etc.

need to be tested.

Product features：

(1) When constant current and voltage are used, it can automatically cross transform to maintain the

characteristics of both control and protection.

(2) The output current is constant, and the output waveform is a pure sine wave, which can be used as 

an over-current test instrument.

(3) It can carry resistive, inductive and capacitive loads to meet the requirements of low-voltage electrical 

appliances for test power supply.

(4) Outstanding advantages, high current stabilization accuracy, and constant output current.

(5) It can be used for automatic test of different current levels and cyclic test operation.

(6) Frequency adjustable range: fixed frequency 50Hz/60Hz, frequency modulation 45Hz~65Hz.
