The inverter is a kind of low-voltage (12 or 24 volts or 48 volts) direct current to an electronic device 220 volts alternating current. Because we usually 220 volts AC into DC rectifier to use, and the role of the inverter on the contrary, hence the name. COTEK inverter SK series of pure sine wave inverter followed the S? Good Design series is COTEK? New series of high power transfer efficiency, small size, light weight and other characteristics of high-frequency pure sine wave inverter. Outstanding design to make products more compact, mobile devices and independent small-scale off-grid solar power systems provide a more pure AC power, energy-efficient multi-stage design is SK? One of the most important characteristics of products provide users with a broader more saving application mode. SK?
