"SK Series" pure sine wave inverters are similiar to the "S Series". They are designed for heavy-duty use and are microprocessor controlled, but only meet UL/cUL standards and are not fully listed. They are FCC compliant. Main difference- "SK Series" has a higher surge rating-designed for high start-up loads. Also available in 48VDC-call for pricing.
The Cotek SK3000-112 high efficiency microprocessor controlled DC-AC inverter converts 12 Volts DC (Nominal) to 3000 watts of pure sine-wave AC power at 100/110/120 Volts, 50/60 Hz. The unit comes with input battery cable lugs and dual NEMA 5-20R GFCI receptacles. Features include overload, short circuit, over-temperature, under & over voltage protections, low power saving mode to conserve energy. The unit is e-13/ CE / FCC approved and the safety standards of the unit conform to UL-458 specifications.
