InPower SSC21-150 Solid State Contactor
The SSC21-150 is part of InPower’s second generation family of high current solid-state DC contactors. These single channel power switches are rated at a continuous current rating of 100, 150, and 200 amps respectively. Low on-resistance solid-state switches and high current fly back diodes provide not only outstanding surge current capability for starting high in-rush current loads but also maximum voltage spike suppression for loads.
Applications
include high current DC loads such as master battery disconnect switching, blower motors, auxiliary air conditioner units, lights, and hydraulic motors.
LED Status Indicator
displays a steady on when the contactor is on and operating normally, or flashes when the contactor has automatically turned off as a result of a detected fault such as loss of ground, overcurrent, under-voltage or over-temperature.
Control
of the unit is acomplished by applying a voltage on the control terminal to turn the unit ON. This voltage turns the unit ON when it is >8.0Vdc. Once the output has been turned ON, if the voltage on the control terminal is removed (or falls below 4Vdc) the unit output is turnned OFF and can be turned ON again when the voltage is >8.0Vdc. In the case of a shutdown due to a Fault, the removal of the Control Voltage (or removing power from the BAT+) and then reapplying >8.0Vdc on the control terminal, will turn the output ON again if the faults are no longer present.
Voltage Hysteresis
on the control input ensures high electrical noise immunity. An input control voltage greater than +8 volts will turn the contactor on and a voltage of less than +4 volts will turn the contactor off. The control input appears as 120 K-Ohm resistance to ground.
Packaging:
The solid-state contactor is packaged in an plastic case with metal baseplate. The Control Input and GND Terminal utilize 8-32 studs with Brass nuts. Connect the GND terminal to a solid Battery Ground. Connections for the high current DC cable utilize ?”-16 threaded stainless steel studs with brass contact pads for low contact resistance. The low voltage disconnects are packaged in an plastic case with an anodized aluminum baseplate. Four corner mounting hole pads provide attachment to the mounting surface.
