DC 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 impedance characteristics of the load 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.

Accept custom current sources with any voltage and current range.
The constant current power supply is specifically designed and manufactured for low-voltage electrical users. It maintains a constant and unchanging output current, with a pure sine wave output, which can serve as a test instrument for overcurrent detection.
This constant current source supports resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power supplies.。
Outstanding features include high flow precision, with levels of 1%, 0.8%, 0.5%, and 0.3% available based on the user's environment. It ensures a constant output current. Previous large current generator solutions have been affected by temperature changes, leading to varying copper resistance in wires, connectors, and coils, necessitating frequent adjustments of the voltage regulator by operators to maintain a constant current, which is time-consuming and labor-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 best choice. This includes setting the action current for thermal relays and measuring the thermal trip current for circuit breakers, among others.
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 (more fixed output frequencies within a broader range can be designed according to customer requirements)
Simulated signal control can be set for users.
Applications include: 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.
