GENERAL DESCRIPTION
The SSR Power Unit is a solid state relay which can switch load currents up
to 45 Amperes @ 240 VAC. The unit interfaces directly with a SSR Drive
Module (OMD00003). The input and output terminals are isolated from each
other to eliminate ground loops and noise problems. The unit features a zero
voltage turn-on and a zero current turn-off detector to minimize radiated RFI
when switching. An internal snubber minimizes inrush currents and guards
against false triggering of the output; related to high dv/dt applications. A low
DC control signal of +3 to +32 VDC is all that is needed for the switching
operation. The solid state switch, highlighted by the inverse-parallel SCR
output, provides a greatly increased operational life over a mechanical relay by
avoiding the usual relay contact problems: arcing, bouncing, mechanical
failure, etc. The solid state relay is shipped mounted to the high efficiency
heatsink for immediate installation.

ORDERING INFORMATION
INSTALLATION
It is recommended to mount the unit outside of an enclosure in an area where
there is unrestricted air flow. The unit should always be mounted with the fins
in a vertical position to maximize heat dissipation. If mounting the unit inside
an enclosure, the internal temperature of the enclosure will normally be higher
than the surrounding area and must be accounted for. At full rated load, the unit
will dissipate 50 watts and achieve a case temperature in excess of 90°C. In all
installations, it is important to allow at least two inches around the power unit
for proper ventilation.
