Solve many power-related problems with TSi Power’s rugged, VRp series- Precision PWM Line Conditioners for machinery. From unstable branch circuits, unstable power grid, poor local distribution, bad wiring and frequent generator cycling, to frequent switching loads in your premises causing untold voltage sags & surges, we have your situation covered.

TSi Power offers a full range of Precision Line Conditioners, based on VRp technology with PWM continuous seamless correction of voltage, surges, spikes, sags & brown-outs.

TSi Power’s VRp series of line conditioners are available for a variety of CNC, automation & robotics, power looms, packaging & printing machine applications, in indoor version. They are compact, light-weight, tightly regulating Line
conditioners 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 remote locations.

TSi VRp series Precision PWM Line Conditioner is available as an indoor model in sizes up to 100 kVA, depending on voltage fluctuation range. TSi VRp series features power efficiency of 95% to 97% when regulating and higher
when voltage is normal.

TSi VRp series Precision PWM Line Conditioner’s standard listed models are highly standardized for performance consistency & fast delivery. Consequently, standard listed models can generally be made available ex-stock
or, at the latest, within 2 weeks.
