The P-1400 AR E accepts any input voltage from 188V to 270V and transforms it to a constant output of 230V or 240V (switchable), ±10V. Voltages beyond that range may also be converted to usable levels, depending on the range variance. Additionally, the P-1400 AR E 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.
