CST Crydom HDC Series Installation Sheet

HDC Series
DC Load Solid State Contactors
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.
FEATURES

MOUNTING INSTRUCTIONS
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.
Mounting on Heat Sink
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.
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 heat sink (See fig. 1). 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.
For optimal thermal performance heat sink fins should be oriented vertically to promote
natural airflow.
Mounting on Panel
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.
Be sure to use thermal pad or thermal compound between the SSC and the panel.

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

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.

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
insulation wire installing capable.
For maximum ratings, for 160 Amp models use Crydom lug terminal TRM3/0 or
other lug terminal with a diameter of 0.375 in (9.52 mm), 2/0 AWG (67.4 mm
insulation wire installing capable.
Wire Size
Maximum wire size capacity per terminal: Input 12 AWG (3.31 mm
Quick Connect Terminals, Output 2/0 AWG (67.4 mm
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.
Important Considerations
WARNING! Do not try to unscrew Terminal Studs from Product.
Be sure to use input and output voltages within operating ranges.
