1. Introduction
The InPower Ambulance Module Power Disconnect Switch is intended for use in ambulances to disconnect battery
power from module loads, such as emergency lights, patient compartment lights, floodlights and loading lights. The
module contains a high current solid state contactor (power switch), a current sensor and a microprocessor control and
monitor circuit. Its over-current shutdown rating is 275 amps with a surge rating of 800 amps, and it provides automatic
fault shutdown for over current and loss of ground. The standard model described in this manual is SSC42-275, but
many custom programs are available. Please call us for more information.
Five control inputs offer a variety of different control configurations, including up to three time delayed power shut-off
modes. Input A allows instant shut-off, Inputs B, C and D offer time delayed shut-off modes, and Input E cancels all
timed shut-offs.
An amber LED indicator displays the power switch status. It illuminates any time the power switch is on, and it flashes
when switch is on and the timer is running in a timed shut-off mode. The LED blinks at a fast rate to indicate a fault shut
down condition.
The DC power terminations are two 3/8 - 16 threaded studs with brass contact pads. The five control inputs are 0.25
inch male faston blade terminals. The four mounting holes provide the required connection to ground.
oad Considerations: Relays/Solenoids on the output must incorporate Fly Back Suppression Diodes/Circuitry.
L
These Relays/Solenoids (without suppression) can create large voltage and current spikes which damage electron-
ics. Having inductive loads without suppression violates your unit's warranty and may damage your vehicles elec-
tronics!

- Page 3 3. System Operation 3.1 Electronic Power Switch The SSC42-275 module power disconnect switch is 100% electronic. When activated, it connects the LOAD terminal to the +BATTERY terminal, delivering power to the module’s 12 Vdc loads. The highly efficient power switch has a very low on-resistance, resulting in a very low voltage drop and low internal heat dissipation. As many DC loads are inductive, the power switch contains an internal clamping diode between its LOAD terminal and ground.
