DC Constant Current SourceA broadband, 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., which require experimentation.
Product Features:

Measurement Functions: Voltage, Current, Frequency, Active Power;
Features power-off memory function and shortcut keys.
Key lock feature, user-friendly design, prevents accidental operation.
Standard with RS232 communication interface, optional RS485 communication interface or remote control port.
Accept custom current sources with any voltage and current range.
The Constant Current Source is specifically designed and manufactured for low-voltage electrical equipment users. It provides a constant and unchanging output current, with a pure sine wave output waveform, and can be used as an overflow detection test instrument.
This constant current power supply supports resistive, inductive, and capacitive loads, meeting the requirements of low-voltage electrical appliances for test power.。
Outstanding advantages: high flow precision, available in 1%, 0.8%, 0.5%, and 0.3% levels according to the user's environment. Ensures a constant output current. Previous large current generator solutions have been affected by temperature changes, causing variations in wire resistance, connectors, and coil copper resistances, necessitating frequent adjustments of the voltage regulator by operators to maintain a constant current. This is time-consuming and energy-intensive, and the precision cannot compare to this power source. In low-voltage electrical appliance production, where current calibration and aging tests are required, using this power source is the optimal 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 (items: 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 wider range can be designed according to customer requirements)
User-defined analog (signal) control available
Product Applications: 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.
