Corona Treater Generators

About

The generator, also known as the power supply, must operate under a wide range of conditions. When starting the corona treater, the power supply is required to run at a high resistance, no load condition until corona discharge is achieved. At this point, the resistance of the air gap between the electrode and the ground roll decreases dramatically and the loading rapidly increases. The generator must adjust with the sudden change in loading and must also be capable of obtaining full power over a wide range of load conditions. QC Electronics’ power supply automatically compensates for changes in loading so manual adjustments are not required.

Our team of engineers will match the correct power supply size to your corona treater in order to provide you with maximum power output.  Our modular power supply technology is based on over 34 years of experience in power supply service, design and manufacturing.

QC’s generator is constructed with the industry’s latest state-of-the-art inductive SCR technology. Unlike IGBT, SCRs can withstand short circuits as in pin-holed electrodes and roll coatings without damaging high-power components in the power supply.

SCR technology is guaranteed to produce the higher power densities. SCR technology has proven to produce higher dyne levels with faster line speeds. This technology is only available through QC Electronics.

All QC generators perform in 132°F ambient temperatures.

Sizing available up to 40 Kilowatts.

Reliable Corona Generators

  • New advanced electronics eliminate the need for a factory service engineer on-site; all maintenance can be handled over the phone.
  • With the purchase of a spare parts kit, any member of your maintenance team can repair the power supply.  Unlike most machinery, our power supply requires no on-site field service.
  • As always, we offer 24 hour support with available technicians.
  • Automatic load matching: senses what the load is and automatically adjusts.

Our latest investment was the complete redesign of our NEXTGEN-i power supply. We developed the new design with a focus on new capabilities, longevity, and ease of operation in mind. The power supply is now controlled by an advanced operating platform using FPGA control. This allows the system to be more efficient and customer centric. The power supply is completely touch controlled; this allows you to access important operation information and run quick glance diagnostics.

Key Features

New Design

A brand new power supply design. The new design includes an advanced monitoring platform using SMT circuits. This allows the system to run more efficiently. Quick glance diagnostics using LEDs and touch panel operations display make the power supply ultra user-friendly. The new design allows the power supply to be connected to any load for a smooth, precise, and reliable corona treatment process.

SCR Technology

QC power supplies use SCR technology rather than IGBT. Unlike IGBT, SCRs can withstand short circuits as in pin-holed electrodes and roll coatings without damaging high-power components in the power supply. One of these components is a trip circuit to put the power supply in the off-state if a short circuit is detected. Our SCR technology has also proven to produce higher dyne levels with faster line speeds. Our power supplies are guaranteed to produce the highest power density of any corona treating power supply on the market. This technology is only available through QC Electronics.

Control Board

The new control board has self diagnosing features built in for quick, on-site troubleshooting with component specific fault icons.

Watt Density or Kilowatt Control

Run an automated set watt density program, or a fixed kilowatt output.

Watt Density Alert (WDA)

Watt Density Alert (WDA) compares programmed power to actual output power and notifies the operator of power density changes.

Touch Panel Control

The touch panel offers intelligent automation of the corona treater for ease of operation and increased functionality. Standard display features include line speed, frequency monitoring, auto/manual start, true kilowatt output, advanced digital fault log, watt density control, kilowatt control, a spare parts list and more. Units are also available in analog control for customers looking for ultimate simplicity.

QC will match the correct power supply size to your corona treater in order to provide you with maximum power output. Our modular power supply technology is based on decades of experience in the design and manufacture of corona treater generators.

Due to continuous product development, key features, specifications, and options are subject to change.

Manufactured in the United States of America in the great state of Wisconsin.
