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.

OPERATING MODES
Start: When either FWD or REV Control signal is applied, and after Control Signal Validation Delay, DC power
supply on terminals 1/- and 2/+ is directly connected to Load at terminals 3/L1 and 4/L2 with a polarity according
to the control signal. The start option can be combined with Stop and/or Dynamic Brake options.
Stop: Load is disconnected from DC power supply. All FET switches (S1, S2, S3 & S4) inside the DP Series SSC are
turned off. This simple Stop option is available only in combination with the simple Start option (suffix Blank).
Soft Start/Ramp Up: It is a modified Start where the DC power supply is connected to the load using a 200 Hz pulse
width modulation with a duty cycle going from 10% to 100%. Soft Start/Ramp Up time is defined by SA, SB and SC
suffixes. After Soft Start/Ramp Up time is elapsed, the Load will remain continuously energized for as long as FWD
or REV Control signal is applied. This option can be combined with Soft Stop/Ramp Down and Dynamic Braking
modes, but not with simple Stop.
Soft Stop/Ramp Down: It is a modified Stop where the DC power supply is disconnected from the Load using a 200
Hz pulse width modulation with a duty cycle going from 100% to 0%. After Soft Stop/Ramp Down time is elapsed,
the Load will remain continuously de-energized waiting for a new FWD or REV Control signal. Soft Stop/Ramp
Down time is tied to Soft Start/Ramp Up time selected by SA, SB and SC suffixes and can be combined with
Soft Start/Ramp Up only.
Dynamic Brake: It could be used as a modified Stop where the FET switches inside the DP Series SSC are
arranged in such a way that they provide a path for the Load Current to keep flowing after the DC power supply
has been disconnected. This mode allows for energy stored in some type of loads to be discharged. i.e. back
EMF on DC motors. Timing for Dynamic Brake is selected by suffixes B2, B5, B8 and B where the latest will
keep the braking or discharging path enabled for as long as FWD and REV Control signals are removed.
Interlock: It will shut down all FET switches inside the DP Series SSC within 0.2 sec after both control signals
FWD and REV are applied at the same time. An Interlock condition will trigger a modified Stop such as Soft
Stop/Ramp Down or Dynamic Brake whenever an option has been selected.
