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

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.
