Options
A Solid State Relay family
designed to switch various
loads such as heating ele-
ments, motors and transform-
ers. The relay is capable of
switching high voltages up to
600 VACrms. The built-in
varistor secures transient pro-
tection for heavy industrial
applications.
For higher reliability and load
cycle capability three semi-
conductor power units are sol-
dered directly on to the direct
copper bonded (DCB) sub-
strate.
AC- or DC-controlled versions
are available. Built-in LED sta-
tus indication for applied con-
trol voltage and over-tempera-
ture alarm (optional). A version
that can be controlled with 5
VDC @ 15 mA (max) is also
available (LD).
The series covers a range of
load currents up to 75
AACrms.
