The Mercury DC to AC power inverters use a modified sine wave to power mains equipment from 12v battery. They are ideally used as a back up during a power outage or for use when travelling. The modern electronics provide a stabilised 240V mains output voltage with short-circuit, overload protection and soft-start circuitry to protect equipment on power up. Ideal for use with TVs, computers, hand held tools, kettles and other appliances.
