COTEK SK3000 SINEWAVE INVERTER
12V, 24V or 48V
Cotek Inverters

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% ).
  • Low power saving mode to conserve energy
  • RS232 interface / remote control port
  • Built-in voltage and watt meters
  • Load controlled cooling fan
  • Advanced microprocessor
  • Short Circuit / OverVoltage / UnderVoltage / OverTemperature / OverLoad protection
  • Output Voltage / Frequency switch selectable
