COTEK SK700W & SK1000W SERIES available in 12V, 24V or 48V PWM Pure Sinewave

700 & 1000W 12V, 24V or 48V Click here to return to Inverter Page

PWM High Frequency Pure Sinewave Inverter provides an economical way to get instant AC power anywhere and at anytime as long as a battery is handy. The inverter converts a DC power source (e.g. from a car, truck, boat or standard battery; or solar panels) to 230 VAC power. The inverter range is specifically suitable for solar installations. High frequency PWM technology ensures a compact unit providing high reliability and performance. The inverter has a robust design and is quiet and portable. It can therefore be operated in almost any environment. The unit has a high current start up capability, protected against short circuit, reverse polarity and over load. The unit also has automatic load sensing (important for solar applications). Warning : Do not operate inverters in wet or moist environments Applications : Lights, drills, general electrical tools, computerised instruments, medical equipment, emergency power, computers, TV sets, radios, satellite receivers, fans, small water pumps, etc. Pure sine wave output (THD< 3% ). Output Frequency : 50/60Hz switch selectable Input & output fully isolation design High efficiency 88 - 93% Capable of driving highly reactive & capacitive loads at start moment Tri-Color indicators display input voltage, output load level and failure status Load controlled cooling fan Advanced microprocessor Short Circuit / OverVoltage / UnderVoltage / OverTemperature / OverLoad protection
