Constant Current SourceA wideband, high-precision, low-harmonic and distortion-stable current source. This constant current source maintains a stable output current even when the external power grid source fluctuates or the electrical load's impedance characteristics change. The power supply is primarily used for products and locations where specific current thermal effect applications and tests are conducted, such as circuit breakers, fuses, thermal relays, magnetic starters, coils, etc., requiring experimentation.

The constant current power supply is specially designed and manufactured for low-voltage electrical equipment users. It provides a constant and unchanging output current with a pure sine wave output, serving as a detection overcurrent test instrument.
This constant current source supports resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power supply.。
Outstanding features include high flow stability accuracy, available in 1%, 0.8%, 0.5%, and 0.3% levels according to the user's environment. Ensures a constant output current. Previous large current generator solutions, due to temperature variations, have seen changes in copper resistance of wires, junctions, and coils, requiring operators to frequently adjust voltage regulators to maintain a constant current, which is time-consuming and energy-intensive. Moreover, the accuracy cannot compare to this power source. In low-voltage electrical production, where current calibration and aging tests are required, using this power source is the optimal choice. This includes setting the trip current for thermal relays and measuring the thermal trip current for circuit breakers, etc.
Automated testing for various current levels (projects: voltage, current, frequency, rise/fall time, with repeatable test operations)
Frequency Range: 40-500HZ (optional), Fixed Output: 50HZ, 60HZ (fixed output frequencies within a wider range can be designed according to customer requirements)
User configurable analog (signal) control
Product applications include: AC circuit breakers, AC contactors, mechanical switches, electronic switches, thermal relays, plastic case circuit breakers, miniature fuses, and testing equipment for switches requiring setting of rated and operating currents, short-circuit protection current, and instantaneous current.
