Corona Treater Generators

Achieve higher power densities and faster line speeds with QC Electronics’ generators. Our modular power supply technology is based on over 35 years of experience in design, manufacturing, and service.

High-Performance Corona Treater Generators by QC Electronics

The generator, or power supply, is an essential component of a corona treater. At QC Electronics, our power supplies are designed to operate efficiently under a wide range of conditions, automatically compensating for changes in loading without requiring manual adjustments. Our team of experienced engineers will help match the correct power supply size to your corona treater for maximum power output.

The QC Electronics power supply boasts a distinctive attribute that sets it apart as the leading choice in the industry. Its functionality is unparalleled, and we encourage you to reach out to us to learn more about this key selling point. Our team is eager to demonstrate the unparalleled benefits of our power supplies and how they can enhance your operations.

Our generators are constructed with the industry’s latest state-of-the-art inductive SCR technology, which is proven to produce higher power densities and faster line speeds. Unlike IGBT, SCRs can withstand short circuits such as those caused by pin-holed electrodes and roll coatings without damaging high-power components in the power supply.

We guarantee our SCR technology will produce higher dyne levels at faster line speeds, and it’s only available through QC Electronics. Additionally, all our generators are built to perform in 132°F ambient temperatures.

QC Electronics offers generator sizing up to 40 Kilowatts for your corona treater needs. Choose QC Electronics for reliable, high-performance generators and superior corona treatment technology.

Reliable Corona Generators

  • New advanced electronics eliminate the need for a factory service engineer on-site; all maintenance can be handled over the phone.
  • No internet connection required for service.
  • 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. Our technicians are expert engineers and are available by personal phone to ensure weekend and evening support in the event of an emergency.
  • 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.


Interfacing a power supply with a line CPU for control is an essential aspect of modern power management systems. By connecting the power supply to a line CPU, operators can remotely monitor and control the performance of the power supply, adjust settings, and troubleshoot issues from a centralized location. This level of control not only enhances the accuracy and efficiency of power management but also improves the overall safety of the system. With the ability to monitor and control power supply performance in real-time, operators can respond quickly to any unexpected changes, minimizing the risk of damage or downtime.

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.
