SPR-20i

About the SPR-20i

The Furman SPR-20i is a high-performance AC power conditioner and voltage regulator designed for demanding audio, video, and broadcast applications. It provides a stable 120 VAC output voltage with a regulation range of +/- 1.0V typically, from input voltages between 113VAC and 126VAC. The unit features Furman's exclusive Linear Filtering Technology (LiFT) that dramatically reduces AC noise (EMI and RFI) across a wide frequency range, improving audio clarity and video picture quality. It also includes Series Multi-Stage Protection (SMP), a virtually maintenance-free surge suppression system that protects connected equipment from voltage spikes without sacrificing itself. The Extreme Voltage Shutdown (EVS) feature automatically powers down the unit if input voltage exceeds 137 volts, protecting equipment from extreme surges. The SPR-20i uses zero-crossing solid state technology to provide virtually unlimited peak current delivery (60 amps peak), avoiding current limiting issues common in other regulators. It has 12 rear-panel outlets: 4 linearly filtered outlets and 8 outlets with additional ultrasonic filtering for digital or video components. The unit is rack-mountable, weighs 31 lbs, and consumes about 12 watts for its display and control circuits. It includes digital meters for input voltage, output voltage, and current load monitoring. The SPR-20i is engineered in the USA and backed by a 5-year parts and labor warranty with a connected equipment warranty up to deductible.
