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

The constant current power supply is specially designed and manufactured for low-voltage electrical equipment users. It features a constant and unchanging output current, with a pure sine wave output waveform, and can be used as an overcurrent detection test instrument.
This constant current source can handle resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power supplies.。
Outstanding features include high flow stability accuracy, available in 1%, 0.8%, 0.5%, and 0.3% levels based on the user's environment. Ensures a constant output current. Previous high-current generator solutions have always been subject to changes in temperature, copper resistance in wires, connectors, and coils, requiring operators to frequently adjust voltage regulators to maintain a constant current, which is time-consuming and labor-intensive. Moreover, the accuracy cannot match this power supply. In low-voltage electrical production, where current calibration and aging tests are required, using this power supply is the best choice. This includes setting the action current for thermal relays and measuring the thermal trip current for circuit breakers, etc.
Automated testing for various current levels (items: voltage, current, frequency, rise/fall time, with recyclable test operations)
Frequency Range: 40-500HZ (optional), Fixed Output: 50HZ, 60HZ (additional fixed output frequencies within a wider range can be designed according to customer requirements)
User-defined analog (signal) control is available.
Product Applications: AC circuit breakers, AC contactors, mechanical switches, electronic switches, thermal relays, molded case circuit breakers, miniature circuit breakers, and testing equipment for switches requiring setting of rated and trip currents, short-circuit protection current, and instantaneous current.
