Category: Watlow

The DIN-A-MITE® B 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 are standard on

every control. There is no need to worry about mercury,

the DIN-A-MITE controller is mercury free.

Features include single-phase and three-phase zero

cross switching up to 40 and 22 amperes, respectively,

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.

A shorted output alarm option is 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.
