Watlow DIN-A-MITE A Power Controller

SORDS ELECTRIC sells the Watlow DIN-A-MITE Power Controllers

The Watlow® DIN-A-MITE® Style A power controller provides 

a low-cost, highly compact and versatile solid state option 

for controlling electric heat. You also get all the quality you 

expect from a Watlow designed and manufactured product. 

DIN-rail and back panel mounting is standard on every 

controller. There is no need to worry about mercury, the 

DIN-A-MITE controller is mercury free. 

Capabilities include single-phase zero cross switching up 

to 25 amperes at 600VÅ(ac) (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 or Vı(ac/dc) 

input contactor versions are available. All configurations 

are model number dependent and factory selectable. This 

power controller also includes 200KA short circuit current 

rating (SCCR) tested up to 480VÅ(ac) to prevent arch flash 

with required fusing. 

The DIN-A-MITE power controller is made in the 

United States.
