The G3N series of solid state relays are used
to control large resistance heaters in
conjunction with temperature controllers.
Solid state relays are SPST, normally open
switching devices with no moving parts,
capable of millions of hours of operation.
By applying a control signal, an SSR
switches ON the AC (or DC) load current,
just as the moving contacts do on a
mechanical relay. Three-phase loads can be
controlled using 2 or 3 SSR’s. Use 3 SSR’s
for Y or star 3-phase loads using a neutral
line. Two SSR’s will control “delta” loads
with no neutral line. Three solid state relays
are also used when there is no neutral load
to provide redundancy and extra assurance
of control.
“Switching” takes place at the zero voltage
crossover point of the alternating current
cycle. Because of this, no appreciable
electrical noise is generated, making SSR’s
ideal for environments where there are
apparatuses susceptible to RFI.
