DIN-A-MITE® C
SCR Power Controller
Delivers Up to
80 Amperes in a
Compact Package
The DIN-A-MITE® C silicon controlled rectifier (SCR) power
controller provides a low cost, 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, panel mount and
through-wall mount versions are available.
Features include single-phase, three-phase/two leg, and
three-phase/three leg, 24-600VAC operation. Current
switching capabilities range from 30 to 80A depending
on the model ordered.
Variable time-base, linear voltage and current process
control or VAC/VDC input contactor versions are available.
Single-phase, phase angle firing and current limiting are 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.

Extended Heater and Power Controller Life with Variable Time-Base
With variable time-base control, the power controller automatically
adjusts the time-base and output power with respect to the
command signal. Accelerated life testing shows that variable
time-base control significantly reduces expansion and contraction
of the heater element. This extends heater and power controller life
while improving process temperature control. This saves money on
heaters, downtime and maintenance.
Single-Cycle, Variable Time-Base Output
Models: DC_ _ - _ _S_ - _ _ _ _
25% Power Output: 1 AC cycle on, 3 cycles off
50% Power Output: 1 AC cycle on, 1 cycle off
Loop-Powered or Transformer Powered
Loop-Powered
By using a temperature controller’s 4-20mA process output signal
as the power supply for the DIN-A-MITE input, the cost of the power
controller can be reduced. With control option F0 the 4-20mA
control signal simultaneously powers the DIN-A-MITE’s internal
electronics and provides the input command signal.
Transformer-Powered
DIN-A-MITE controllers with single-cycle, variable time-base or phase
angle outputs (control options L, P and S) detect the power line zero
cross with a transformer that also powers their internal electronics.
These units can be controlled manually with a potentiometer or
automatically with a temperature controller using any of the control
options: 4-20mA, linear voltage (0-5,1-5 and 0-10VDC).
Loop-Powered, Variable Time-Base Output
Models: DC_ _ - _ _F0 - _ _ _ _
20% Power Output: 3 AC cycles on, 12 cycles off
50% Power Output: 3 AC cycles on, 3 cycles off
80% Power Output: 12 AC cycles on, 3 cycles off
With loop-powered, variable time-base control, the minimum on
or off time is three cycles.
Phase Angle Output
Models: DC1_ - _ _ [L, P] _ - 0_ _ _
Phase angle control (control options L and P) is infinitely variable
over the period of the AC sine wave. It provides a variable voltage
and/or current output. The phase angle circuitry is transformer
powered and accepts a linear voltage, current or potentionmeter
input.
With single-cycle, variable time-base control, at 50 percent
power, the output is on for one cycle and off for one cycle.
At 25 percent, it is on for one cycle and off for three cycles.
Under 50 percent, the output is not on for more than one
consecutive cycle; over 50 percent the output is not off for
more than one consecutive cycle.
