By applying a control 2500 Vrms input/output to ground signal, an SSR switches “ON” the ac load current, just as the moving contacts do on a mechanical for Vac and Vdc Input Models contactor. Three-phase loads can be controlled using 2 or 3 SSR’s.

Because of this, no appreciable electrical noise is generated, making SSR’s ideal for environments where there are apparatuses susceptible to RFI. P-157 MADE IN Solid State Relays USA These SSR’s are of the twin SCR type, FHS Heat Sink Dimensions and Specications inherently more reliable and capable FHS-1 and FHS-2 Heat Sink Dimensions of higher overloads before failure than triacs. Heat is developed in a solid state relay due to the nominal voltage drop A across the switching device. To dissipate (0.167) B the heat, an SSR must be mounted on a nned heat sink or aluminum plate. An SSR should be located where the ambient temperature is relatively low, since the current switching rating is 8-32 TH'D lowered as the temperature increases. (2.000) (4.750) 2 Places (0.200) (4.416) Another SSR characteristic is a small leakage current across the output when the relay is open. Because of this, a voltage will always exist on the load side of the device. In comparing SSR’s with mechanical R (0.250) (1.875) C (0.125) (1.5748) contactors, the SSR has a cycle life many times that of a comparably priced contactor. However, SSR’s are Dimensions shown in mm (in) more prone to failure due to overload and improper initial wiring.
