The CH gives infinite control for noninductive
loads up to 15 Amps on 120 or 240 Vac (cannot
be used with external contactor). It can be
turned either to left or right to select proper
heat from 0-100% wattage with infinite control
over the first 50% of total wattage.
Energized continuously in HI position, at other
settings it delivers selected input level under
control of a simple bimetal timer.
Only 3 mounting holes are necessary to install
the CH in customer supplied box or panel. It is
designed for use at ambient temperatures up
- Simplicity of design with no cams or levers
to adjust, and no motor to burn out.
- Automatic compensation for line voltage
fluctuations up to ± 15%.
- Bimetal acts at settings less than HI to limit
electrical input and reduce temperature.
