Figure 1
General Description
The PowrTwin is a manually adjusted, dual output, solid-state power controller. It is
designed to provide precise and variable control to resistive loads up to 14 amps total: 7
amps per circuit. Operation is stable in ambient temperature from 30 to 130 degrees F.
Control Features
1. Lighted On/Off switch per output
2. 7-amp relay output per circuit.
3. Non-Linear control (scale is for reference only)
4. Individual circuit protectors
5. Low profile modular housing.

How to Setup and Operate
First connect the heater load (7 amps or less) to the load receptacle on the rear panel.
Next plug the control line cord into the appropriate 3-wire grounded power receptacle.
Toggle the lighted power switch to the “ON” position to apply power to the controller.
Turn the control knob to the desired setting. As the knob setting is increased, voltage to
the load increases. Full line voltage is applied at a dial setting of 100 percent. Settings
below 100 percent are not linear. Verify voltage prior to operation.
Manual power controls require experimentation to achieve the desired control setting for
a particular application. The PowrTwin offers precise repeatability once the desired
setting has been determined for that application.
