DIN-A-MITE® D

SCR Power Controller
Delivers Up to
100 Amperes in a
Smart Package

The DIN-A-MITE® D silicon controlled rectifier (SCR) power
controller provides an inexpensive, versatile product for
controlling heat in an efficient package. This controller
is designed and manufactured with the quality features
expected from Watlow®. The mounting footprint matches
that of the industry standard mercury displacement
relay, but there is no need to worry about mercury, the
DIN-A-MITE controller is mercury free.

The DIN-A-MITE Style D is capable of zero cross switching
up to 100 amperes single-phase, at 600VAC at 86°F (30°C),
depending on the model selected. Combining the input
of two or three controllers allows control of three-phase
loads. The controller is completely touch-safe and includes
on-board, front-accessible, semiconductor fuses. Options
include a current transformer for load current monitoring
and a shorted output alarm. The controller is UL® 508, C-UL®
and CE approved making it ideal for panels and cabinets that
require agency approvals.

Variable time-base, 4-20mA process control and VAC/VDC
input contactor options are available. All options are model
number dependent and factory configurable. This power
controller also includes 200KA short circuit current rating
(SCCR) tested up to 480VAC to minimize damage in the
event of a short circuit when used with required fusing.
