EXTEND THE LIFE OF YOUR HEATERS

ACHIEVE OPTIMUM

CONTROL WITH ZERO
CROSS SWITCHING

Zero cross switching extends life of
the power controller and heater by
switching fast, and providing
more accurate control of both
the heater element and the
process. With this improved
control, you’ll also see an
increase in parts produced
and less scrap, for improved
productivity and efficiency.

• Accurate control

• Improve productivity

PROTECTION FOR YOUR

SYSTEM

Zero cross switching produces minimal
RFI (radio frequency interference) to
help prevent electrical noise that could
possibly
interfere with other
equipment in your
system. This added
protection for your
entire thermal
system provides
you with less total
system downtime and less
maintenance for your system.

• Eliminate downtime

• Reduce system maintenance

RUGGED, BACK-TO BACK

SCR DESIGN ENSURES
LONG TERM RELIABILITY

The DIN-A-MITE meets high current
application requirements, tolerates

spikes and dissipates
less power. When
used properly, the
DIN-A-MITE outlasts
any other type of switch.
There’s no limit on the
number of cycles the
DIN-A-MITE can handle.

REDUCE WEAR ON

THERMAL SYSTEM

With optional variable time base
switching, the DIN-A-MITE output
automatically adjusts cycle time to

meet the demands of the
system. You’ll see benefits
such as:

• Less power required
by the thermal
system

• Heater output
equal to need

SYSTEM FAILURE

PREVENTION

A proven high current connection
scheme ensures optimum electrical
connection to prevent
heat buildup, which could
lead to system failure.

To ensure overall reliability
and reduce fear of hot
spots, we’ve eliminated
wires and fasteners which could
possibly break down and loosen,
as with other power controllers.

• Prevent heat buildup

• Improve reliability

SET POINT DEVIATION CAUSED BY SWITCH TYPE

Mechanical contactors suffer wide temperature deviations due to long cycle time.

MDRs can beswitched faster than contactors, but still deviate considerably from set point.

DIN-A-MITEs eliminate deviation, providing optimum control and long heater life.

Heaters switched using mechanical contactors suffer wide deviations due to long cycle
times—typically 30 seconds—needed to preserve life. Control is poor, heat is wasted, and
excessive expansion andcontraction of the heating elements shortens heater life. MDRs
can beswitched faster than contactors and will hold the heater closer to set point, but still
suffer deviations.

Fastest of all are solid state devices such as the DIN-A-MITE configured with variable
time base. Switching as fast as three ac wavecycles (less than 0.1 seconds), set point
deviation is virtually eliminated, giving the finest control, lowest power consumption,
and longest element life.

EASY AS A, B, C OR D, WATLOW HAS

A DIN-A-MITE FOR YOUR APPLICATION

OVENS AND FURNACES

In a coatings application, the
customer needed to rebuild an oven
to improve heater life and temperature
control, plus reduce electrical noise.
They needed a product that would fit in
the existing cabinet to avoid the costs
involved with increasing the size of the
cabinet. The customer replaced all of
the 100 amp mechanical contactors with
Watlow’s 100 amp DIN-A-MITE SCR
power controllers. This customer was
able to use the existing control panel
and mount the DIN-A-MITE controllers
in less space than the mechanical
contactors. Additionally, the
DIN-A-MITEs provided on-board
current transformers as well as
built-in semiconductor fusing.
These controllers improved heater
life and process temperature control
while reducing electrical noise with
zero cross firing.

Watlow’s variable time base DIN-A-MITE
controllers help to maintain process set
point without any overshoot or droop
variations in temperature, ensuring a
quality process. The small size of the
DIN-A-MITE means the size of clean
room control panels will be minimal,
thus saving money.

• Saves valuable space to increase
flexibility in semiconductor processing

• Minimal RFI to ensure long life of the
heaters and other system equipment.

LASTICS

P

In plastics processing, Watlow’s
DIN-A-MITE is an ideal replacement for
MDRs in injection molding, extrusion,
blown film extrusion and blow molding
systems. You’ll get better control of the
heater and the process, more
accurate temperatures, a more
consistent product, less rejects and
reduced downtime.

• Ovens/Furnaces

• Packaging

• Petroleum/Chemical

• Plastics

• Semiconductor

• Wave Solder and
Reflow

SEMICONDUCTOR

Watlow knows the importance of
controlling temperature in the
semiconductor manufacturing process.
Even the slightest variation can cause
damage to expensive ingots and chips.

A plastics manufacturer used MDRs
in their equipment, but wanted longer
heater life that relays could not
provide. They were also encountering
some trouble with machines occasionally
shutting down. Watlow
recommended three-phase, two leg
DIN-A-MITE controllers to replace the
MDRs. The DIN-A-MITEs fit in the same
footprint as the relays, so there was no
need to reconfigure the machine
to accept the new controllers. The
DIN-A-MITEs also eliminated electrical
noise and prevented machine
stoppages, therefore reducing
downtime.

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 process input. Accelerated life testing verified 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. You save money on heaters, downtime and
maintenance.

Loop Powered or Transformer Powered

Phase Angle

Models: DC1_ -_ _ [L, P] 0 - 0_ _ _

Phase angle (input control type “P”) phase control is infinitely
variable inside the sine wave. This provides a variable voltage
and/or current output. This option includes soft start and line
voltage compensation. This is transformer powered and
therefore will work with a linear voltage, current input or a
potentiometer input. This is single-phase only.

Loop Powered

By using a temperature control 4-20mA process output signal as
the power supply for the DIN-A-MITE input the cost of the power
control can be reduced. With zero cross (burst fired) the 4-20mA
input signal simultaneously performs the tasks of providing a
power supply and an input command signal. The DIN-A-MITE
“F0” input control signal is a loop powered option and will work
as single- or three-phase. It works only with a 4-20mA input.

Transformer Powered

Some DIN-A-MITE models require that an on-board power
supply be used to power the internal electronics. Phase angle
options require that we detect the zero cross of the ac sine wave
and thus a transformer is required also. The DIN-A-MITE input
control signal types “L”, “P” and “S” are transformer
powered and can be controlled manually (open loop) with a
potentiometer input or in the auto mode (close loop) with a
temperature control using any of the 4-20mA, linear voltage
(0-5,1-5 and 0-10VÎ(dc)) input types.
