PART NUMBER NOMENCLATURE

Crydom’s advanced DC Switching Technology is now conveniently packaged in a High Power

“H-Bridge” configuration with optional Soft Start/Ramp Up, Soft Stop/Ramp Down & Brake

features for use in DC Load Reversing applications including motors, brakes, clutches, electro

magnets, solenoids, plating baths and electrolytic cells. The DP Series Solid State DC Reversers

are an all-solid-state design with 2.5 Kv Optical Isolation and incorporate low dissipation power

FETs for fast and efficient Load control.

Convenient FET switches in H-bridge configuration

Built-in protective Forward/Reverse interlock function

UL & IEC ratings for general use & Motor loads

MOUNTING INSTRUCTIONS

Mounting on Heat Sink

Mounting on Panel

Please read all installation instructions before using your DP Series Solid State Contactor (SSC).

Choose one of the two mounting options and follow the instructions.

Locate the panel section on which the DP Series SSC will be mounted. Panel mount

surface must provide adequate heat sinking capability.

(B)

Be sure to use thermal pad or grease between the SSC and the panel.
DP Series Contactor mounting slots have a diameter of 0.2 in (5.0 mm). Four screws are

needed (not included) to mount the SSC onto panel. Choose screw length considering the

mounting surface and that DP Series baseplate thickness is 0.125 in (3.2 mm).
Before applying full torque tighten down all 4 screws until they contact the baseplate.

Then, tighten them to 20 in-lbs (2.2 Nm) starting with one immediately followed by the one

in the diagonally opposite corner. After the first 2 screws are completely tightened,

proceed tightening the remaining 2 screws.

Select adequate heat sink (see thermal derating

curves).
Be sure to use thermal pad or grease between the

SSC and the selected heat sink.
DP Series Contactor mounting slots have a diameter

of 0.2 in (5.0 mm). Four screws are needed (not

included) to mount the SSC onto heat sink (See Fig.

1). Choose screw length considering the mounting

surface and that DP Series baseplate thickness is

0.125 in (3.2 mm).

For optimal thermal performance heat sink fins should be oriented vertically to natural

airflow.
