Watlow DIN-A-MITE SCR Power Controller User manual

SCR Power Controller
Delivers Up o 100 Amps
in a Smart Package
The Watlow®DIN-A-MITE®Style D Silicon Controlled
Rectifier (SCR) power controller provides you with an
inexpensive, versatile product for controlling heat in an
efficient package. You also get all the quality you expect
from a Watlow designed and manufactured product. The
standard back panel mounting footprint is equal to that of
an industry standard mercury displacement relay. 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 amps single-phase, at 600VÅ(ac) at 86°F (30°C),
depending on the model selected. Combined with the input
of two or three controllers and you can control three-phase.
It is totally touch-safe and includes standard back panel
mounting, on-board semiconductor fuses (accessible from
the front) and a current transformer option for external load
current monitoring. An optional “shorted SCR detector”
feature is available on some models. This model is UL®508
and C-UL®and CE approved. These agency approvals are
ideal for those panel builders that require agency approvals
on their panels and cabinets.
Variable time base, 4-20mA process control, or Vı(ac/dc)
input contactor options 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 Style D power controller is made in the
United States.
