PROFILE
Zero crossing relay with antiparallel thy-
ristor output is the most used solid state
relay in industrial applications.
In fact, it can be used for resistive, inducti-
ve and capacity loads.
“Zero crossing” relay is energised when
voltage meets the zero point and disener-
gised 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 elec-
trical connection between relay terminals
and the load.
Varistors, fuses, thermostats and fans are
available as fittings.
Use the relay with an opportune heatsink
(see section accessories).
