● It originates that controlled by CPU completely, increasing the stability of good quality, at the same time, it reduces the cost of production, which make the possibility of pure sine wave inverters ( and UPS) entering into the household market come true, it resolved the troubles of power cut completely. ● unique overload design, originate in the seven seas. With the lowest capacity, it can drive the largest impactive loads (such as tube lightings, energy-saving lamps, refrigerator, TV set, air-conditioner, and generator and so on), such usages cannot be achieved by all other UPS and inverters. It creates a miracle in this field and promotes technical innovation waves in this field. ● Functions that when the commercial power comes, it will start the unit automatically: when it overloads, it will close the unit automatically; when you cancels the load, it will restore to normal etc. are humanized designs. And it is a real intelligent household uninterrupted power supply. ● Full automatic transformer time less than 4ms, even though your computer won’t restart. ● Protections against output short-circuit ● with powerful and stable recharging function, make sure that in an extremely short time, it will charge the batteries fully. And its over-age recharging current is up to 10 Amps.
