Reliable Powers™ Controls Meets Mechanical Needs

Powers mechanical line voltage equipment includes room thermostats, detection thermostats, switches, and a humidistat that provide the control you need in commercial, industrial, and residential installations.

The ET 134 line voltage room thermostat is a wall mounted instrument available with exposed or concealed set point adjustment. Models are available with Single-Pole, Single-Throw (SPST) or Single-Pole, Double-Throw (SPDT) contact action and for standard-duty (nominal ¼ hp; 10 amps, non-inductive) applications. Rugged and reliable, these “non-powered” On-Off thermostats provide a proven means of control in demanding heating and cooling applications.

The Electric Low Temperature Detection Cut-out and Alarm Thermostat is a remote bulb instrument which opens an electrical circuit to stop the supply fan motor and/or closes an outside air damper when the temperature at the sensing element falls below the setting of the instrument. Simultaneously, it closes a circuit to indicate an alarm condition. The ET 141 remote bulb thermostat incorporates a temperature-sensitive liquid-filled sensing element that actuates precision snap-acting switches through a diaphragm and linkage mechanism. The switches are Single-Pole, Double-Throw (SPDT) snap-acting type, totally enclosed, and are suitable for low or line voltage power switching.

The switches are Single-Pole, Double-Throw (SPDT) snap-acting type, totally enclosed, and are suitable for low or line voltage power switching. The electric surface mounted thermostat has a Single-Pole, Double-Throw (SPDT) contact mechanism and is designed especially for mounting on pipes.

The electric surface mounted thermostat has a Single-Pole, Double-Throw (SPDT) contact mechanism and is designed especially for mounting on pipes. The ET 141 high limit control thermostat is duct mounted and has a rigid bulb, bi-metal rod and tube construction.

The SW 134 Pressure Electric Switch actuates electrical circuits from pneumatic control signals. The 134 Pressure Electric Switches are heavy duty pressure-actuated, mechanical contact type switches used to open or close electrical circuits from pressure signals in pneumatic control systems.

The line voltage humidistat is a wall-mounted instrument with SPDT snap-acting contacts to control humidifying or dehumidifying equipment. The 134 Humidistat has a setpoint range of 0 to 70% RH as well as “OFF” dial positions for humidification and dehumidification and is suitable for residential, commercial, and industrial applications.
