Constant Current Source | High Precision Adjustable DC Current Source
Technical characteristics
● AC constant current source is specially designed and manufactured for low-voltage electrical appliance users. Its output current is constant, and its output waveform is pure sine wave. It can carry resistive, inductive and capacitive loads, meet the requirements of low-voltage electrical appliances for test power supply, and can be used as an over-current test instrument.
● Outstanding advantages, high current stabilization accuracy, can be used according to the user's environment. Ensure constant output current.
● Automatic test of different current levels can be carried out (items: voltage, current, frequency, lifting time, and cyclic test operation)
● Frequency adjustable range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (fixed output frequency within more ranges can be designed according to user requirements)
Product application
● AC air switch
● AC contactor
● Mechanical switch and electronic switch
● Cable and wire
● Automatic detection and calibration platform
● Large current capacitor electrical appliances
● Thermal relay, molded case circuit breaker, small circuit breaker and the required rated current, action current, short-circuit protection current, etc
