MCU 502

Fiber optic bus controller

Safe connections to operating computers

The MCU 502 fiber optic bus controller transfers signals from the MPD 500 and MPD 600 partial discharge (PD) measurement devices to the operating computer via a fiber optic bus. The MCU 502 is powered via the USB cable, and the measurement procedure is controlled conveniently from the operating computer. Since no electrical connection to the MCU 502 is necessary, the devices are electrically isolated for a high level of safety and signal integrity.

Key features

  • Electrically isolated PD signal transmission
  • Operation via the PC software
  • Integrated sensor for triggering to the mains frequency


  • Electrically isolated signal transmission from MPD devices to the operating computer during PD measurements
