1.1. GENERAL PRESENTATION

7200S series solid state contactors control the electrical power to three-phase industrial

loads such as low temperature coefficient and short wave infrared elements.

Standard ratings in the series range from 16 A to 200 A,at voltages from 200 V to 500 V.

7200S series solid state contactors comprise two channels, controlled by thyristors.

Depending on the type of control signal and the type of input specified, 2 operating modes

are available: logic (‘on/off ’) or modulation (‘Burst mode’).
