Constant Current SourceA wideband, high-precision constant current source with low harmonic and distortion. This constant current source maintains a steady output current even when the external power grid fluctuates or the electrical load's 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., where experiments are conducted.

The constant current power supply is specifically designed and manufactured for low-voltage electrical equipment users. It features a constant and unchanging output current, and the output waveform is pure sine wave, making it suitable as an overcurrent 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 stability and flow accuracy, which can be adjusted to 1%, 0.8%, 0.5%, or 0.3% levels according to 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 resistance,接头, and coil copper resistance, necessitating frequent adjustments to the voltage regulator by operators to maintain a constant current. This is time-consuming and labor-intensive, and the accuracy cannot compare to this power supply. In low-voltage electrical production, where current calibration and aging tests are required, using this power supply is the best choice, such as setting the operating current for thermal relays and measuring the thermal tripping current for circuit breakers.
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 (additional fixed output frequencies within a wider range can be designed according to customer requirements)
Simulated quantity (signal) control can be set for users.
The product is applicable to: AC circuit breakers, AC contactors, mechanical switches, electronic switches, thermal relays, plastic-case circuit breakers, miniature circuit breakers, as well as testing equipment for setting rated and operating currents, short-circuit protection current, and instantaneous current switches.
