Eurotherm Thyristors and Solid State Relays
Logic Power Controllers Solid State Relays
Our range of solid state relays can drive resistive heating elements from a few watts up to hundreds of kW. Models are available to take AC and DC logic
signals as well as analog inputs.
The formula below provides a simple way to calculate the thyristor current (IT) for various resistive loads. The calculated value of IT should then be multiplied by 1.2 to allow for variations in supply voltage and manufacturing tolerances of the load.
