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 situation covered.

TSi Power offers a full range of Fast Acting PWM Automatic Voltage Regulators (AVR’s), based on VRp technology with PWM continuous seamless correction of voltage, surges, spikes, sags & brown-outs.

TSi Power’s VRp series of AVR’s are available for a variety of services, such as telecommunication, signaling, hospitals, diagnostics, scientific  & analytical equipment, offices, residences, shops & showrooms,
both in indoor & outdoor versions. They are compact, light-weight, tightly regulating AVR’s that respond instantly with a wide input voltage range but without switching the active power path. With inbuilt excellent surge
voltage protection & electrical noise control circuits, using only passive components, our VRp series is your ideal choice for homes, offices as well as remote locations, such as in cell sites, signaling yards & the
like.

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
• Available in sizes up to 45 kVA

 


  • Indoor VRp series Precision PWM AVR

    Available in sizes of up to 45 kVA, standard +20% voltage fluctuation range, the indoor VRp series features power efficiency of 95% to 97% when regulating and higher when voltage is normal.
