SixPack Chassis
The SixPack chassis is a removable unit which holds up to
six C3 (dimmer) or APS6 (ballast) modules. The modules
slide-mount into the chassis and are electrically connected
via euro-connectors. (Blank panel cover plates are installed
in positions where modules are not installed to aid the forced
air cooling.)
Its capability to support both APS6 and C3 modules in any
combination will allow mixing different types of Series 300
luminaires on a single Smart Repeater unit.
To distribute lamp power to Series 300 luminaires, each
chassis is connected to a Smart Repeater unit with a Series 300 trunk cable.
Note: The LVS power supply module 110V mode of operation has been disabled. The chassis will not
operate below 200 volts nominal.
C3 Module
The C3 dimmer module is an electronic dimmer for high wattage
tungsten halogen incandescent lamps. It is used to dim VL5 and VL5B
luminaire incandescent lamps. The module is designed to slide-mount
into any of the front slots on the SixPack chassis, connecting electrically
via euro-connectors.
Since the C3 module does not have its own built-in brightness curve, the
module must be used in conjunction with an SPC-36 controller, which
has the brightness curve in its operating system. The SPC-36 controller
outputs 0 to +10 volts DC, which corresponds to 0% and 100% output
respectively.
A PCB jumper allows the module’s lamp current output to be
configured for 1000 or 1200 watts.
