The 

DP Series of DC Load Reversing Solid State Contactors (SSCs) 

include four optically isolated DC low dissipation FET outputs rated up to 
60 amps at 48 VDC, wired in an H-Bridge configuration with a common 
input control to provide a convenient method to both power on and off and 
reverse the polarity to a variety of DC loads including motors, brakes, 
clutches, electro magnets, solenoids, plating baths  and electrolytic cells.  
The 

DP Series is housed in a compact encapsulated industry standard 75 

x 105 mm panel mount package featuring screw termination for power and 
load connections and a 4 conductor connector for control connections.

In addition to the on/off and reversing functions, 

DP Series Contactors 

include an internal interlock circuit to prevent damage due to overlapping 
forward/reverse control commands . The 

DP Series also offers options for 

a variety of combinations of  Internal PWM Soft Start/Ramp Up, PWM Soft 
Stop/Ramp Down and Dynamic Brake functions.  Available with a selection 
of set ramp times, the soft start and stop functions provide a convenient 
means to eliminate or reduce the mechanical shocks associated with 
starting and stopping DC electro-mechanical loads.

The 

DP Series of Solid State Contactors are available with either  20, 40 or 

60 Amp general use ratings in a 40°C ambient temperature with 
appropriate heat sinking. The output will switch from  1 to 48 VDC.  
Available control inputs are conveniently matched to the input logic supply 
to accept either 4.5 to 15 VDC or 18 to 32 VDC from a common power 
supply. 

DP Series SSCs are CE Certified, RoHS Compliant, UL/cUL 

Recognized and carry Motor Control Ratings up to 15 FLA at 48 VDC.

For additional information about the 

DP Series DC Reversers, including 

available thermal management accessories, contact the nearest Crydom 
Distributor, Representative or local Crydom Sales Office, or visit our
