Mini 300W Inverter 600W Peak 12VDC to 220VAC Pure Sine Wave Power Inverter(QW-P300B)


  • The whole process is executed by CPU intelligent program.

  • Pure sine wave output: Relative to the square wave or modified sine wave ( Step wave), it have a stronger effect in loading or load capacity.

  • Available with capacitive load, inductive load and any other type of general-purpose AC load, if it runs a refrigerator, television or radio equipment, there would be no interference and noise and will not affect the load equipment performance and life. 

  • High stability: Since it has over voltage, under voltage, overload, overheating, short circuit, reverse and improved protection, stability of the system.

  • Digital intelligent control: The core device is controlled by a powerful micro-controller, making the external circuit structure being simple, control being flexible and control strategy being powerful, thus ensuring excellent performance and stability

  • Maximum 300W continuous output and 600W surge power.

  • Convert efficiency: ≥90%

  • Overload protection: Yes

  • Short circuit protection: Yes

  • No-load current: ≤0.5A

  • Waveform distortion: ≤5%(Linear load)

  • Waveform: Pure Sine Wave

  • Work temperature:-10 degree ~ 50 degree

  • Temperature protection: 60 degree ~ 70 degree

  • Frequency: 50Hz

  • Green led indicator: Lighting(working), Flash slowly(lack voltage), flash fast(fault occur and the unit is in protection situation
