Specifications for the Larkin M3K Power Semiconductor Tester

Larkin_M3KPower Semiconductors are a family of devices used in all types of industries mainly for AC/DC conversion and motor speed control.

It is imperative that only instruments specifically designed for testing Power Semiconductors are used.

The Larkin Power Semiconductor Tester – Model M3K can test forward or reverse leakage currents at voltages up to 3300V – Designed for testing High Voltage Rectifier Diodes, SCRs/Thyristors, and Power Modules (including IGBTs and Darlington Transistors.
