PMP SERIES
Introduction
PROPORTIONAL CONTROL SOLID STATE RELAYS
The PMP Series of micro-controller based Single-Phase Proportional Control SSRs are designed to offer precise control of the power delivered to
a resistive load in a compact 22.5mm housing, with ratings from 25 up to 90 Amps at 90 to 600 VAC. PMP Series solid state relays can vary the
output load power proportionally to an analog control input from 0 to 100%. This can be achieved by two different methods: Phase Angle control
and Burst Fire control (with Distributive Zero Cross). The control method to be used can be selected on the unit by means of a selector switch
located on top of the SSR. This selector switch also allows to select the type of analog signal to be used at the control input. The available input
types are: 0- 5 VDC, 0-10 VDC, and 4-20 mA. PMP Series Proportional SSRs are ideal for lamp dimming and resistive heating control, among other
type of applications requiring proportional control.

INSTALLATION INSTRUCTIONS
Mounting on Heat Sink
Select adequate heat sink (see thermal derating curves).
Be sure to use a thermal pad or thermal compound (0.006-0.008 in layer thickness recommended) SSR and the selected heat sink.
SSR housing mounting holes have a diameter of 0.341in (8.66mm). 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 in-lb (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 in-lb (2.2 Nm) min.
