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 there are fluctuations in the external power grid or changes in the impedance characteristics of the load. 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., where experiments are required.

The Constant Current Source is specifically designed and manufactured for low-voltage electrical equipment users. It maintains a constant and unchanging output current, with a pure sine wave output waveform, and can serve as an instrument for detecting overcurrent experiments.
This constant current source supports 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 operating environment. It ensures a constant output current. Previous large current generator solutions have been problematic due to temperature variations, causing changes in copper resistance of wires, connectors, and coils. Operators have had to frequently adjust voltage regulators to maintain a constant current, which is time-consuming and labor-intensive, and the accuracy is inferior to this power supply. In low-voltage electrical production, where current calibration and aging tests are required, using this power supply is the optimal choice. This includes setting the trip 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 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)
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.
