Communication constant current sourceIt is a wideband, high-precision, low harmonic, and distortion stable current source. This constant current source is an AC power supply that can maintain a constant output current even when there are fluctuations in the external power grid or changes in the impedance characteristics of electricity consumption. This power supply is mainly used in products and places for specific current thermal effect applications and testing. Experiments are required for circuit breakers, fuses, thermal relays, magnetic starters, coils, etc.

The AC constant current source is specially designed and manufactured for low-voltage electrical users. Its output current is constant and the output waveform is a pure sine wave, which can be used as an overcurrent detection experimental instrument.
This communication constant current source can carry resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for testing power supply。
The outstanding advantage is high current stability accuracy, which can be classified into 1%, 0.8%, 0.5%, and 0.3% levels according to the user's usage environment. Ensure a constant output current. The high current generator scheme previously used had to constantly adjust the copper resistance of wires, joints, and coils due to temperature changes. Operators had to frequently adjust the voltage regulator to maintain a constant current, which was time-consuming and labor-intensive, and the accuracy could not be compared to this power supply. In the production of low-voltage electrical appliances, the use of this power supply is currently the best choice for projects that require current verification and aging, such as setting the action current of thermal relays and measuring the thermal trip current of air switches.
Can perform automated testing of different current levels (items: voltage, current, frequency, rise and fall time, with cyclic testing operation)
Adjustable frequency range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (fixed output frequency can be designed according to user needs within a wider range)
Can set analog (signal) control for users
The product is applied to: AC air switches, AC contactors, mechanical switches, electronic switches, thermal relays, molded case circuit breakers, small short circuit breakers, and testing equipment that requires setting rated and operating currents, short-circuit protection currents, and instantaneous current switches.
