  • Reducing High-End Printers’ Vulnerability to Power Quality Issues

    By: David Nystrom

    The modern copier is a tremendously complex machine with many electronic and mechanical devices. The failure or even malfunction of a single component can cause defective printing, a system outage, or even machine failure. For end users, this is an unacceptable and costly loss of productivity from a major capital investment. For dealers, this means a service call using valuable personnel and potential component or product replacement. If the problems persist, reputation damage inevitably follows. While copiers have evolved into very reliable products, they are at risk from ill-understood power quality issues.

  • Cap-Ex, Op-Ex, and Energy Savings from Automatic Voltage Regulators

    By: Nam Paik

    In order to protect sensitive electronic and electrical equipment from unstable AC mains voltage, UPS (uninterruptible power supply) is commonly used. However, UPS is not always an optimal power protection solution due to its high purchase price, low power conversion efficiency (typically around 90%) and high costs due to maintenance, repair and battery replacement. In applications where five to ten minutes of UPS battery backup is not required, a high-performance automatic voltage regulator, such as TSi Power's VRP line, can provide substantial Cap-Ex, Op-Ex, and energy savings.

  • Cap-Ex, Op-Ex, and Energy Savings by Using an Automatic Transfer Switch (ATS) instead of an UPS

    By: Nam Paik

    In applications where there is more than one AC power source, automatic transfer switches (ATS) can be used as a battery-less UPS system. It will provide higher reliability AC power to mission-critical loads at substantially lower cost compared to a traditional UPS (interruptible power supply) system that uses batteries.

  • Designing for Surge Immunity in International Markets that Face Hostile Environments

    By: Peter Nystrom

    Many parts of the world – besides North America and parts of Western Europe – have hostile electrical environments. Systems integrators in telecommunications and other industries that export to these markets need to design equipment that will operate in those environments. This paper discusses factors that may necessitate enhanced surge immunity.
