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

Accept custom current sources with any voltage and current ratings.
The constant current power supply is specially designed and manufactured for low-voltage electrical users. It outputs a constant and unchanging current, with a pure sine wave output waveform, and can be used as an overcurrent test instrument.
This constant current source is capable of handling resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power.。
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 large current generator solutions have been affected by temperature changes, causing variations in wire, connector, and coil copper resistance, necessitating frequent adjustments of the voltage regulator to maintain a constant current. This is time-consuming and labor-intensive, and the precision 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 (projects: voltage, current, frequency, rise/fall time, with cyclic 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)
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 trip currents, short-circuit protection current, and instantaneous current.
