Teardown: Inovance MD210T0.4B Inverter

03 December 2014
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

The Inovance MD210T0.4B inverter is ome of Inovance's compact, low-power-rated motor drives used predominately for small-sized industrial equipment. These products are especially suitable for electronic equipment, commercial food processing machines, packaging machines, woodworking machines, glass-working machines, and similar equipment. The series is characterized by compact design and space-saving parallel installation capability. A simple internal PLC allows 16 levels of speed control, and the inverter's housing permits operation in harsh environments such as high temperatures, high humidity, and heavy dust.

In addition, devices in the series feature fast start and fast stop functions, relatively easy debugging and maintenance, and operation from a common DC bus.

Summary points:

  • Inovance’s MD210 Series Inverter
  • Three-phase 380 VAC model with 400 W maximum power
  • Texas Instruments 32-bit ARM Cortex-M3 MCU
  • Vincotech 1200 V IGBT module
