SCR Power Controls

SCR Power Controls are zero-cross fired or phase angled fired, and are ideal for the control of resistant and transformer coupled loads. SCRs eliminate old fashioned, environmentally unsafe mercury contactors.

SCR Power Controls are protected from line voltage transients, making them more reliable in a variety of applications. The continuous, high repetitious rate of full ON and full OFF cycles produces a smooth power output to the load (heater) and stabilizes temperature, also extends the heater life.

SCR Power Controls differ from other switches. The fast SCR cycle time results in a final temperature much closer to the desired set point and reduces energy costs. SCR Power Controls modulate small increments of power to the load, unlike traditional mechanical control, and eliminates the overshoot and undershoot associated with a load controlled by a contactor.
