AC Constant Current Power Supply "CCFT Series"

AC Constant Current Power Supply "CCFT Series"

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.

Constant current power supply for large coils

Constant current power supply for large coils

Achieving an accuracy of ±0.5% of the actual value! We respond to high precision demands in constant current output.

This is an example of a DC current amplifier for large coils developed and designed by our company. There was a request for a constant current output accuracy of ±1% or less relative to the input voltage. Therefore, we selected high-precision devices for the isolation amplifier used in the control section. By using devices that can achieve an accuracy of 1/100 compared to general-purpose resistors and capacitors, we optimized the circuit design around the isolation amplifier. Additionally, there was a request to minimize the use of magnetic components, so we used materials like aluminum and brass. 【Product Overview (Partial)】 ■ Name: Constant Current Power Supply ■ Application: Constant current power supply for large coils ■ Input Voltage Range: AC 93V to 115V 3φ ■ Output Specifications: 0 to 25V, 5A ■ Number of Channels: 1 channel *For more details, please refer to the related links or feel free to contact us.
