The new powerful PSSR solid state relays are available in single-phase and three-phase versions. Compared to contactors and standard relays, PSSR relays switch silently and practically do not wear out. The device also has a high load factor and can be used in conjunction with fuses. PSSR modules easily handle inductive load peaks.
Due to the fact that PSSR single-phase relays switch when the alternating current passes through 0, the maximum load can reach 20 A at a temperature of 55 ° C. Fields of application: equipment for the production of plastic components or equipment in thermal shops or treatment plants.
Three-phase PSSR relays make instantaneous switching, and as a result can be used in engine control units.
Both versions (single-phase PSSR 1PH and three-phase PSSR 3PH) are ready for use without pre-setting. In other words, after you take it out of the box, just snap it onto the DIN rail and make the electrical connections.
