EUROTHERM has published a free 12-page guide on choosing and using power thyristors for the control of heaters and other electrical loads up to 1200 amps.
As well as describing the wide range of standard single and three phase thyristors available from Eurotherm, the guide provides useful general information on the characteristics of different types (resistive, inductive etc), good application practice and how digital communications can aid process management within multi-zone applications.
The thyristor range outlined in the guide can be utilised for all industrial applications by providing all methods of thyristor firing.
Firing modes such as basic zero crossing logic switching, phase angle firing with current limiting options plus single and multiple cycle firing can all be provided allowing for implementation of high-speed, long life, silent thyristors in place of contacts and relays.
The Eurotherm range of DIN rail and panel mounting thyristors incorporate in-built heatsinks for simplified installation and ease of mounting. The range also offers modules with optional serial communications for Modbus and Profibus.
Modules are also available for complicated applications such as short wave infra red heating. Fault diagnosis indication is provided for load and module faults. Eurotherm Australia 02 9634 8444.
