HDC Series
DC Load Solid State Contactors
FEATURES
PART NUMBER NOMENCLATURE
The HDC Series Solid State Contactors (SSCs) are designed for control of high power DC loads
such as brakes, clutches, coils, electro magnets, heaters, lamps, motors, solenoids, etc., where
long life and fast switching are required and traditional mechanical contactors or relays don’t
provide the required life, performance or service levels. The HDC Series offers the latest in DC
Solid State Power control by virtue of Crydom’s advanced high speed DC switching circuit for
on/off or PWM control (up to 1 KHz) utilizing optically isolated low dissipation FET outputs rated
at either 120 or 160 Amps at 48, 72 or 150 VDC Operating Voltage.
120 or 160 Amp DC Load Ratings @ 40ºC ambient w/heat sink
Single Pole Single Throw Normally Open operation (SPST/N.O.)
LED Input Status indicator standard
IEC 60947-4-1 Rated, UL & cUL
Required for valid part number
For options only and not required for valid part number
(A)
See compatible accessories in TABLE 1.
(B)
For maximum ratings use heat sink ratings shown in HDC series derating curves (see
product datasheet).
(C)
Load can be wired to either terminal 1 or terminal 2. Proper polarity must be observed all
the time for the power supply and load.
(D)
DC inductive loads must be diode supressed. Diode not included.
MOUNTING INSTRUCTIONS
Mounting on Heat Sink
Mounting on Panel
Please read all installation instructions before using your HDC Series Solid State Contactor (SSC).
Choose one of the two mounting options and follow the instructions.
Locate the panel section on which the HDC Series SSC will be mounted. Panel mount
surface must be clean, bare metal and provide adequate heat sinking capability.
(B)
Be sure to use thermal pad or thermal compound between the SSC and the panel.
HDC 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 HDC 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 thermal compound
between the SSC and the selected heat sink.

Wire Size
Maximum wire size capacity per terminal: Input 12 AWG (3.31 mm

) through
Quick Connect Terminals, Output 2/0 AWG (67.4 mm

). Choose wire gauge
according to actual load current. See TABLE 2.
Connections
First install Lug Terminal (Item 1 on fig.2) followed by Washer Int. Tooth-Lock
(Item 2 on fig.2) and finally Nut Hex (Item 3 on fig.2)
Transient Protection
An inductive load will produce harmful transient voltage when it is turned off. The more perfect the switch,
the larger the transient voltage. The MOSFET output is so nearly ideal switch that the transient voltages
produced by seemingly "non-inductive" loads can cause damage if not suppressed. Diodes should be fast
recovery type with PIV rated greater than twice the supply voltage.
Terminals
For maximum ratings, for 120 Amp models use Crydom lug terminal TRM3/0 or
other lug terminal with a diameter of 0.375 in (9.52 mm), 1 AWG (42.4 mm
2
) 75ºC
insulation wire installing capable.

Important Considerations
WARNING!
Do not try to unscrew Terminal Studs from Product.
Be sure to use input and output voltages within operating ranges.
