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.
