INFINITE CONTROLS  Mechanical Bi-Metal operation
Knob setting 0 to 100% Watts
Double Pole, Single Throw (DPST) Snap-Action
Positive Break
120 or 240 V, 1800 and 3600 Watts
Features - Simplicity. No cams or levers to adjust. No motor to burn out.
- Bi-metal acts at settings less than HI to limit electrical input and depress temperature.
- Provides control for loads up to 15 amperes.
- Designed for operation in an ambient up to 180�F.
- Automatic compensation for line voltage fluctuations up to �15%
Gives infinite control for noninductive loads up to 15 amperes on 120 or 240 volts. Can be turned either to left or right to select proper heat from 0 to 100% wattage with infinite control over first 50% of total wattage. Energized continuously in HI position, at other settings it delivers selected input level under control of a simple bi-metal timer. Applications- Annealing
- Melting Pots
- Industrial cooking
- Dies
- Platens
- Comfort heating
- Electric furnaces
- Molding
- Industrial hot plates
- Laboratory ovens

Voltage Control - Solid State Variable Model A18TP  Solid State power controls provide variable control of single-phase constant resistance heating loads. These small, ultra-light controls replace expensive, bulky variable transformers, saturable core reactors, and electromechanical contactors Full-size, easy-turn potentiometers control the output voltage via power semiconductors, replacing failure-prone brushes or moving contacts to heating element temperature in virtually any* process heating application up to 25 amps (6000 watts @ 240VAC). Applications- Replace variable transformers
- Nozzle heaters
- Platen heating
- Band heaters
- Extrusion and Molding machines
- Food preparation
- Environmental chambers
- Heat treating ovens
Specifications - Light ON/OFF switch
- 6ft. power cord with plug
- NEMA standard 120 or 240VAC receptacle (please specify)
- 15amp load capacity at 120 or 240 VAC
- Quick-change " 2-millisecond" fuse protection
- Portable (bench top) or chassis mounted small size
