Module Semikron SKKT 172/16E is a dual thyristor SCR module in a standard housing SEMIPACK 2.

Thyristor module AMKT 172-16E AS ENERGITM is a replacement, analogue, alternative and equivalent

semiconductor device for SCR module SKKT 172/16E Semikron. The thyristor modules are characterized by

high electrical and thermal cycling capability, meaning high reliability and long lifetime in intensive operation

modes. The thyristor modules are housed in a industry-standard housing making it easy to integrate the

device into existing equipment. The main (power) terminals are on the top of the case and are marked as

1, 2, 3 (common anode-cathode, cathode, anode). The control terminals are marked as K1, G1, K2, G2.

Dual thyristor modules are used in various power equipment - power and control units, power regulators,

AC regulators, DC motors control, AC motor soft starters, converters, controllers of blast furnaces or chemical

processes, welding equipment, and as rectifiers for AC converters.
