CVM75BB160 SanRex - Thyristor / Diode Module

CVM75BB160 Description

The SanRex CVM75BB160 is a thyristor module, rated for 1600 V and 75 A. It is used in phase-controlled rectifiers, soft starters, battery chargers and temperature controllers for furnaces and heaters. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.

We help engineers and repair technicians find parts like the CVM75BB160, including obsolete ones. Send a quick RFQ for current pricing and delivery. Before ordering, please confirm ratings and pin-out with the official datasheet.

Target Applications

SanRex CVM75BB160 is used for Welding and Plasma Cutting machines, Rectifier in Switch Mode Power Supplies (SMPS), Uninterruptible Power Supplies (UPS) and Motor drives.
