This manual also contains all user-pertinent specifications and semiconductor fusing recommendations. Refer to national and local electrical code safety guidelines whenever you install electrical equipment. The Watlow DIN-A-MITE power controller includes single-phase, 3-phase, 2-leg, and 3. DIN-A-MITE C. The DIN-A-MITE C silicon controlled rectifier (SCR) power controller provides a low cost, compact and versatile solid state controller option for controlling electric heat. This solid state controller is designed and manufactured with the quality features expected from Watlow.
