Measurements and Monitoring Board

ARCTU3I board was especially designed for power converters control systems and protection. Normalized voltage signals of 3 currents, 1 voltage and one temperature are available on a single DIN connector.

ARCTU3I can be used with 1 to 3 phase inverters and rectifiers or any other converter in the limit of inputs number and nature. Each channel can be turned on/off by the end user.

ARCTU3I also includes an automatic or manual (or both) brake control output compatible with ARCAL gate drivers.

  • 3 phase currents (and sum) with overcurrent protection and grounding detection.
  • Isolated DC voltage with brake control and overvoltage signal.
  • Heatsink temperature monitoring with overtemperature signal.
  • Fully isolated up to 4KV.
  • Single 20 to 35V supply voltage with internal monitorings.
  • Wide operating temperature range : -40 / +85°C
  • General error and overtemperature outputs on positive or negative logic.
