Cotek Inverters : Sinewave

COTEK SK200W & SK350W SERIES available in 12V or 24V
High Frequency PWM Pure Sinewave

200W & 350W
12V, 24V or 48V

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).

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% ).
Input & output fully isolation design
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
