Infralight Technology
offers a full
range of SCR
digital power
controllers
with phase
angle
and burst
firing
(zero-cross) to
suit many industrial
applications: Industrial
heating, furnaces,
kilns, variable resistive loads, transformer coupled loads, fast
response
loads, high in-rush current, short wave infrared, standard resistive
loads, silicon carbide elements. Infralight
Technology's solid state
SCR power
controllers complement the
rapid switching required by PID controllers giving
optimum
performance and equipment lifetime. Available in
single phase and 3-phase, Infralight Technology's digital scr power
controllers
are
able to efficiently control all industrial
heating applications.
SCR Power Controllers
Thyristor
power controllers precisely regulate output power/voltage or
current to
resistive heating loads such as industrial furnaces and ovens. They can
be interfaced with computers and software that can monitor and/or
control power throughput.
Next Generation of Digital Power Regulators
-
Phase
Angle Switching:
- Controller allows partial waveform
through
during every half-wave cycle.
Zero Cross
Switching
- Controller allows
proportion of complete half-waves through to regulate power.
Specifications
Important
operating specifications for SCR power
controllers include the phase, operating voltage, and maximum
current. Phase choices for SCR power controllers include single
phase, three phase 2-leg, and three phase 3-leg. Operating
voltages for SCR power controllers include <100 VAC, 100-199 VAC,
200-299 VAC, 300-399 VAC, 400-499 VAC, and > 500 VAC. The
maximum current is the maximum rated current of the SCR power
controller.

Operating
features to consider when specifying SCR power controllers include
command signals, control feedback, diagnostic indicators, soft start,
and failure detection or alarm. Command signal choices include
analog voltage, analog current, and potentiometers. With an
analog voltage command signal the output of the controller is regulated
by varying an analog input voltage signal. With an analog current
command signal the output of controller is regulated by varying an
analog input current signal. The output of controller can
be regulated by varying a potentiometer, often in the form of a
dial on the front panel. Control feedback choices are voltage,
current, or power. Diagnostic indicators are visual indicators
during ON condition (needles, LEDs, etc.) A soft start provides
for a gradual ramp-up of output for load protection. Failure
detection or alarm uses circuitry that detects failures such as short
circuits or missing cycles and provides interlock signal or audible
alarm.
Mounting
choices for SCR power controllers include open panel, enclosed wall
mount, rack mount, DIN rail, and freestanding or cabinet. Open
panel SCR power controllers are wall-mounted with open, accessible
electrical components. In an enclosed wall mount an enclosure is
provided along with mounting holes on the enclosure. A rack mount
unit is designed to be mounted in a rack assembly. A DIN rail
mounted unit is designed for mounting on a standard DIN Rail.
Freestanding or cabinet units stand on the floor or are integrally
mounted in the cabinet. An important environmental operating
parameter to consider when specifying SCR power controllers is
operating temperature.
