MITS's yk PSW xx 150 (1500W) of inverters provides 1500W of pure sine wave AC power from a DC source. Pure sine wave AC power is the best for powering highly inductives as well as highly capactive loads. Unlike modified sine wave inverters. It offers "clean" power ideal for powering sensitive loads for absolute AC equipment peformance. Low EMI levels allow for usae with minimum interference to other equipment such as sentsitve navigation and sophisicated devices.
