Constant current source:
Technical characteristics:
1. 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.
2. Outstanding advantages, high current stabilization accuracy, can be used according to the user's environment. Ensure constant output current.
3. Automatic test of different current levels can be carried out (items: voltage, current, frequency, lifting time, and cyclic test operation)
4. 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:
1 AC air switch
2 AC contactor
3 Mechanical switch and electronic switch
4 Cable and wire
5 Automatic detection and calibration platform
6 Large current capacitor electrical appliances
7 Thermal relay, molded case circuit breaker, small circuit breaker and the required rated current, action current, short-circuit protection current, etc
