User’s Manual
DIN-A-MITE Solid-State Power Controller
Please consult this user’s manual when you
place your new DIN-A-MITE into service. It
contains all the necessary information to mount
and wire the product into the application. 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-
phase, 3-leg, 120 to 600VÅ (ac) operation.
Current switching capabilities range from 30 to
80A, depending on the model ordered. See the
output rating curves.
Zero-cross variable time base or V‡ (ac/dc) input
contactor versions are available. Shorted SCR
(silicon controlled rectifier) and open-heater
protection is available on some zero-cross
models. Phase angle and phase angle with
current limit is also available on single-phase
models. The model number indicates the power
controller’s configuration.
The DIN-A-MITE power controller is designed and
manufactured by Watlow in Winona, Minnesota.
