PMP SERIES
PANEL MOUNT PROPORTIONAL CONTROL SOLID STATE RELAYS
MOUNTING INSTRUCTIONS
ORDERING OPTIONS
WIRING DIAGRAM
Crydom PMP Series Solid State Relays were developed to offer precise control of the power delivered to an AC load in a standard 22.5 mm industrial package. Quick and easy installation is coupled with low drive
power requirements and efficient, reliable power SCR output. This compact new design offers up to 90 A
RMS
in ambient temperatures of 40ºC.
Be sure to visit the product series datasheet available at the Sensata website to complement this information. If you have questions or need additional information please contact Tech Support. Please read all
instructions before using your Proportional Control Solid State Relay (SSR)
INSTALLATION GUIDE
Choose one of the two mounting options and follow the instructions.
Mounting on Heat Sink
• Select adequate heat sink (see thermal derating curves in product series’
datasheet).
• Be sure to use a thermal pad or thermal compound (0.006-0.008 in layer
thickness recommended) between the SSR and the selected heat sink.
• SSR housing mounting holes have a diameter of 0.341 in (8.66 mm).
Two screws are needed to mount the SSR onto a heat sink (See fig.1).
Mounting screws are sold separately as HK8 and are suitable for all
Crydom heat sinks.
• Otherwise, recommended screw size is 8-32 (socket) using an allen
wrench (9/64 in) for the installation. Choose screw length considering
mounting surface hole depth and SSR baseplate thickness of 0.125 in
(3.2 mm).
• Before applying full torque tighten down both screws until they contact the baseplate.
• Then, tighten them to 20 lb-in (2.2 Nm) min.
• For optimal thermal performance heat sink fins should be oriented vertically to promote natural
convection airflow.
Mounting on Panel
• Locate the panel section on which the SSR will be mounted. Panel mount surface must provide
adequate heat sinking capability, uncoated, clean, flat (0.004 in/in recommended) and preferably
aluminum.
• Be sure to use a thermal pad or thermal compound (0.006-0.008 in layer thickness recommended)
between the SSR and the panel.
• SSR housing mounting slots have a diameter of 0.341 in (8.66 mm). Two screws are needed (not
included) to mount the SSR onto a panel. Mounting screws are sold separately as HK8. Otherwise,
recommended screw size is 8-32 (socket) using allen wrench (9/64 in) for the installation. Choose
screw length considering the mounting surface and that the SSR baseplate thickness is 0.125 in
(3.2 mm).
• Before applying full torque tighten down both screws until they contact the baseplate. Then, tighten
them to 20 lb-in (2.2 Nm) min.
