Linear amplifier type AC constant current power supply! Accurately measure the time until cutoff.
The "CCFT Series" is a frequency-variable AC constant current power supply. It adopts a linear amplifier circuit method, ensuring low distortion by controlling the instantaneous waveform to produce a sine wave output current. Its fast rise time allows for precise measurement of the time until the current flows through breakers, etc., and is interrupted. By using a separate transformer, it reduces the connection impedance with the workpiece, allowing for a cost-effective proposal by keeping the power supply capacity low. Customization is available for 2kVA and above, as well as for other specifications, so please contact us. 【Features】 ■ Low distortion ■ Accurate measurement of interruption time ■ Customizable ■ Output signal during current flow to external contacts (optional) ■ Ability to output current synchronized with the phase of an external voltage by inputting external voltage (optional) *For more details, please refer to the PDF document or feel free to contact us.
