Products Description
Product overview：
The HCT series is a high-precision constant current source with stable current output and low harmonic distortion. This constant current source maintains stable output current even when external power grid fluctuations occur or electrical impedance characteristics change. It is primarily used in products and testing environments requiring specific current thermal effects.
Product features：
● When using constant current and constant voltage, it can be automatically cross-transformed to maintain the characteristics of both control and protection;
● The output current is constant, the output waveform is pure sine wave, can be used as an overcurrent detection instrument;
● Can be a resistive, inductive and capacitive load, to meet the requirements of low-voltage electrical appliances for test power supply;
● High stability and high precision to ensure constant output current;
● Automatic test can be performed at different current levels, and the operation can be tested repeatedly.
App industries：
Applied in motor electronics industry, colleges and universities, laboratories and research testing, industrial and mining enterprises, electrolytic electroplating, charging equipment, aging electronic components and other fields.
