The 15 Amp P-1800 AR delivers a stable 120 volts of AC power to protect equipment from problems caused by AC line voltage irregularities such as sags, brownouts, or over voltages – all of which can cause sensitive electronic equipment to malfunction or sustain damage. The P-1800 AR accepts input voltages over a wide AC voltage range and transforms it to a constant output of 120V, +/- 5V. Voltages beyond that range may also be converted to usable levels, depending on the range variance. Additionally, the P-1800 AR is a full-featured power conditioner that filters and purifies AC power, reducing line noise and ensuring optimum performance. Not only will your equipment perform better with Furman’s Linear Filtering Technology (Lift), but it will also be fully protected by our exclusive Series Multi-Stage Protection (SMP), and Extreme Voltage Shutdown (EVS). This circuitry provides the highest level of power protection available.
