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

The Constant Current Source is specifically designed and manufactured for low-voltage electrical equipment users. It features a constant and unchanging output current, with a pure sine wave output waveform, making it suitable 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 advantages include high flow precision, which can be adjusted to 1%, 0.8%, 0.5%, or 0.3% levels based on the user's environment. It ensures a constant output current. Previous high current generator solutions had varying copper resistance in wires, connectors, and coils due to temperature changes, requiring operators to frequently adjust voltage regulators to maintain a constant current, which was time-consuming and labor-intensive, and the accuracy could not 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 thermal trip current for thermal relays and measuring the thermal release current for circuit breakers, etc.
Automated testing available for various current levels (projects: voltage, current, frequency, rise/fall time, with cyclic test operations).
Frequency range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (fixed output frequencies within a broader range can be designed according to customer requirements)
Users can set analog (signal) control for the simulation.
Applications include: AC circuit breakers, AC contactors, mechanical switches, electronic switches, thermal relays, molded case circuit breakers, miniature circuit breakers, and testing equipment for setting rated and trip currents, short-circuit protection current, and instantaneous current switches.
