Schneider VZ3TM1425M1671 SCR Rectifier Module

Core Performance & Industrial Application

The Schneider VZ3TM1425M1671 is a high-power SCR thyristor rectifier module for Schneider Altivar 61 and Altivar 71 series heavy-duty inverters.

It is used in the input rectifier section of ATV61HC50N4 and ATV71HC40N4 drives to convert AC input into DC bus voltage.

It has 425A rated current and 1600V blocking voltage, with excellent surge current resistance and stable thermal performance.

It adopts compact power module package, built-in thermal conductive base for heat dissipation matching with inverter radiator.

It supports direct replacement for the original SCR unit, helping restore the normal operation of high-power variable frequency drive.

It is widely used for heavy-duty fan, pump, compressor and industrial transmission frequency conversion equipment maintenance.
