Automatic Voltage Regulators

TSi Power’s voltage regulators are designed for applications where stable power is a requirement.

Solve many power-related problems with TSi Power’s rugged automatic voltage regulators (AVRs). From unstable branch circuits, unstable power grid and poor local distribution to bad wiring and frequent generator cycling, we have your application covered.

TSi Power offers a full range of automatic voltage regulators, including VRP with PWM continuous seamless correction, SLC with four-tap relay switched regulation and FLC with a saturated ferroresonant transformer.

TSi Power’s indoor and outdoor AVRs are available for a variety of applications, including industrial, telecom and medical. Our VRP line is a compact, light-weight, tightly regulating line conditioner that responds instantly with a wide input voltage range but without switching the active power path. The SLC line is a low-cost solution suitable for low-power applications. And, the FLC line is designed for loads that are stable and cannot tolerate any short-term interruption in voltage. With excellent surge voltage protection, FLC’s lack of active components makes it ideal for remote locations.
