(For some models)
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, accelerate 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.

OPTICAL ISOLATION ADAPTER
With optical communication, isolation control is performed. As complete isolation is provided by optical fiber, it can protect the unit against transients caused by surges, inductive lightning, external noise, etc.
- Extremely safe operation is possible since there is no upper limit to the breakdown voltage theoretically.
- Stable communication is possible even in an overly noise environment.
