Solid State Relays
Gefran’s Solid-state relay or SSR is a device that uses electronic anti parallel transistor technology to perform the switching function of controlling an electrical load, typically a resistivity load.
Zero crossing relay with anti parallel theorist output is the most used solid state relay in industrial applications.
In fact, it can be used for resistivity, inductive and capacity loads.
“Zero crossing” relay is energised when voltage meets the zero point and dis-energised when current meets the zero point, depending on the signal control on the input circuit.
This relay has been designed to stand high-value transitory applications .
When the relay has to stand high currents for a long period, it is necessary to grant a proper dissipation and an adequate electrical connection between relay terminals and the load.
Correct management of electrical heating elements for industrial heating applications requires robust, safe, interference free, fast and diagnostically capable static contactors.
The range of static contactors GRS meets all these requirements with current ratings from 15 to 120 Amperes and voltages up to 600 V AC, with extremely compact size in every single current level.
