IDENTIFYING THE SOLID STATE RELAYS
Chapter 1 IDENTIFYING THE TE200S SOLID STATE RELAYS
GENERAL INTRODUCTION TO THE TE200S SERIES
The TE200S series of solid state relays (SSRs) are thyristor units designed to control the elec-
trical power in industrial three-phase loads.
A TE200S series SSR is made up of two channels, each comprising a pair of thyristors con-
nected in anti-parallel, and a direct (unswitched) channel.
The TE200S series is designed to control three-phase resistive loads:
• elements with a low temperature coefficient
• short-wave infrared elements (except for the 63A model).
Three-phase loads can be connected:
• in star without neutral
• in closed delta
The power wiring is independent of the supply phase rotation.
The nominal line-to-line voltage ranges from 200Vac to 500Vac depending on the product
code of the unit.
The nominal currents, defined at an ambient temperature of 45°C, of TE200S SSRs are
between 16A and 63A per phase, depending on the rating of the unit.
