Pillar UniFoiler 3000, Operator'S Manual

Page: 8 / 39

Introduction
•
The power supply is designed for local connection to the sealing coil. The system is made of
watertight electrical components designed for wash-down applications. The power leads
from the inverter to the coil can be of any practical length since they are not water-cooled.
On the hand held system, the leads are provided as part of the coil, and are 10 feet (3 meters)
in length.
•
Operator panel is mounted directly to the front of the power supply, and compact size allows
for easy mounting on your conveyor line.
•
A standardized coil mounting system accepts any Pillar UniFoiler 3000 sealing coil.
•
Several styles of sealing coils are available to adapt to a variety of sealing needs. The coils
are easily located, adjusted, and connected electrically. All the coils are air-cooled and
require no water cooling for operation.
Some Terms
Some terms used throughout this manual:
Tank Capacitor - Located inside the enclosure that covers the top of the sealing coil is a
capacitor. It works together with the sealing coil to generate the high-energy electro–magnetic
field. Locating the capacitor at the coil eliminates the need for heavy, water- cooled leads to the
coil.
MOSFET - Metal-Oxide-Field-Effect-Transistor - A type of transistor that can accommodate
high frequency switching for inverters.
Impedance - Relationship between voltage and current. An electrical value associated with
ability of the inverter to match the sealing coil's electrical characteristics and power
requirements. This value changes in response to the amount of metal passing through the sealing
coil's electro–magnetic field.
Induction Heating
- The phenomenon causing electrical current to flow in a charge of material
to be heated.
Inverter
- This is the device that changes direct-current power to alternating current, high
frequency power and sends to the sealing coil.
Transformer - The inverter contains a transformer that couples its output to the sealing coil.
Different size bottle caps will load the sealing coil differently. The inverter automatically adjusts
to allow maximum power transfer into the cap.
