SPECIFICATION SHEET

DIN-A-MITE® A

The DIN-A-MITE® A power controller provides a low-cost,
highly 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 and
panel mounting is standard on every controller. There is no
need to worry about mercury, the DIN-A-MITE controller is
mercury free.

Features include single-phase zero cross switching up
to 25 amperes at 600VAC (see rating curve). A unique
integrated design removes the guesswork associated with
selecting a proper heat sink and adequate terminations for
the application.

Variable time-base, 4-20mA process control and VAC/VDC
input contactor versions 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.
