DIN-A-MITE® D

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 (MDR), 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.
