Controlled by various interfaces

The CO/USB series is a line of digital interface adapters controlled by a computer, laptop, or programmable logic controller (PLC) for Matsusada Precision's DC power supplies, high voltage power supplies, AC power supplies, bipolar power supplies, and electronic loads. These products are ideal for enabling multifunctional and high-precision automatic inspection systems, 24/7 production lines, and various system equipment using power supply devices.

The interface adapters enable automation and labor-saving in manufacturing processes and speed up research and development, and also contribute to improving safety and reliability. In addition to high-resolution 16-bit (1/65535) control, it is equipped with various functions such as readback and status, making it suitable for various applications such as R&D that require high accuracy, quality testing that requires constant monitoring of power supply status, and manufacturing processes.

Optical isolation adapters, such as USB-OPT, CO-E32, CO-OPT2-9, etc., utilize fiber optic cables for digital communication, which enables extremely reliable communication even in noisy environments such as in factories and for long-distance control. By using optical fibers, they are electrically isolated, so safe operation is possible even in power supply configurations with potential differences. In addition, all models are designed to be ultra-compact, palm-sized, and can be installed anywhere. By using them in combination with Matsusada Precision's compact and lightweight power supplies and electronic loads, you can further take advantage of their space-saving features.

Sweep control program for digital converter

Sweep control program

This program is used to gradually change the output of DC power supplies and high voltage power supplies that can be controlled by our power supply digital controller CO-HV series. Any settings are provided as for the voltage/current values when the output starts and reaches, and after the output starts. Following that, the output is activated accordingly.

It is very convenient for such applications like transformation process of the capacitor, aging of electronic components and burn-in testing of semi-conductor etc. where it is necessary to repeat the output by changing the output gently and a decided pattern.

Features and Benefits

  • Fine setting of output voltage and output current is available by high-resolution of 16-bit.
  • Each voltage value and each current value can be set individually.
  • LAN, USB, RS-232C, RS-485 and GPIB communication are available.

Available models

  • CO-HV (High Voltage power supply digital controller)

How to order

To order, add "(s)" after the available Model No.
Example:
CO-HV(s) (with CO-AU cable)

Usage example

  1. Output voltage value setting
  2. Output current value setting
  3. Attained voltage value setting that can be set below value lower than (1).
  4. Attained current value setting that can be set below value lower than (2).
  5. Attained time setting
  6. Output voltage setting after attainment that is selected from 0 V, remain, or value before sweep
  7. Output current setting after attainment that is selected from 0 V, remain, or value before sweep
  8. Choose whether output status signal will be output or not
