Product Description

Product introduction



Product introduction
AC constant current power source is a kind of wide spectrum, high-precision CC, low harmonic distortion CC power source. This constant current source is an AC supply that keeps the output current constant when the power supply of the outside power grid fluctuates or the resistance characteristics of the electricity conformtos changes. This power supply is mainly used in products and sites where specific current thermal effect applications and testing are carried out. Such as circuit breakers, fuses, thermal relays, magnetic starters, coils, etc. need to be tested.
Technical features

1. AC constant current source is specially designed and  manufactured for low-voltage electrical users, its output current is constant, the output waveform is pure sine wave, can be used as a detection overcurrent experimental instrument.
2. This AC constant current source can be with resistance, inductive and capacitive load, to meet the requirements of low-voltage electrical appliances test.
3. Outstanding advantages, high CC accuracy, according to the user's environment has 1%, 0.8%, 0.5%, 0.3% level. The output current is guaranteed to be constant.
4. Can carry out different current levels of automated testing (project: voltage, current, frequency, lift time, can be cycled test operation)
5. Frequency adjustable range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (more range fixed output frequency can be designed according to user needs)
6. For the user to set the amount of analog (signal) control
