DIN-A-MITE® C

SCR Power Controller
Delivers Up to
80 Amperes in a
Compact Package

The DIN-A-MITE® C silicon controlled rectifier (SCR) power
controller provides a low cost, compact and versatile solid
state option for controlling electric heat. This controller
is designed and manufactured with the quality features
expected from Watlow®. DIN-rail, panel mount and
through-wall mount versions are available.

Features include single-phase, three-phase/two leg, and
three-phase/three leg, 24-600VAC operation. Current
switching capabilities range from 30 to 80A depending
on the model ordered.

Variable time-base, linear voltage and current process
control or VAC/VDC input contactor versions are available.
Single-phase, phase angle firing and current limiting are also
available. All options are model number dependent and
factory configurable. This power controller 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.
