Automatic Voltage Regulators

Fast Acting PWM Automatic Voltage Regulators

Our voltage regulators are for applications where stable power is a requirement.

TSI Elecpower introduces the revolutionary PWM voltage regulation technology which solves the various powerquality problems, because it is engineered to maintain stable voltages on real-time basis

We recommend our high-speed PWM automatic voltage regulators (AVR’s), based on our VRp technology featuring continuous seamless correction of voltage, surges, spikes, sags & brown-outs. Our PWM- AVR”s are the complete solution for various incoming power issues originating right from unhinged branch circuits, uneven power failure, poor local distribution to terrible wiring and regular generator cycling. It has inbuilt exceptional regulation speed, surge voltage protection and electrical noise control circuits using only passive devices, which differentiates VRp series from other regulators.
These Automatic voltage regulators are compact, light- weight, rugged and maintenance-free devices that react spontaneously to power fluctuations. The technology works with wide input voltage fluctuation. Our VRp series is the ideal choice for residential & commercial organizations in urban areas as well as in remote areas.
Both indoor and outdoor versions of VRp series of AVR’s are available for a variety of services such as scientific & analytical equipment, hospital, signalling, telecommunication, houses, shops and showrooms.
For technology advantages of our VRp series, refer to the features table under the images.
TSi VRp series PWM AVR’s include:
• Indoor and outdoor versions
