Price's Silicon Controller Rectifier (SCR) acts like an electronic switch that turns on and off large amounts of power to the load (heater).  It provides proportional modulation of the heater's full operating range, ensuring reliable, efficient and silent operation. 

This controller uses a zero cross-switching feature that allows for a soft start of the electronic load, eliminating power surges.

- Accurately maintains room setpoints, preventing undershooting and overshooting and thereby reducing operating costs
- Silent operation
- Optional discharge air temperature (DAT) proble limits discharge air temperature
- Large, finned aluminum heat sink provides optimal heat dissipation
- Industry-standard inputs accepted
