DC/AC sine wave inverter

February 2009 Maintenance, Test & Measurement, Calibration

The A300-100 series modified DC/AC inverters from Mean Well extends the product range for lower wattage applications. Along with the existing 150 W~2500 W product series, Mean Well can offer a complete line of modified sine wave inverters to fulfil low cost AC applications. A300-100 can provide 100 W continuously and possesses 150 W/3 minutes and 200 W of peak surge capability.

Standard features include:

* Output waveform: modified sine wave.

* USB output port.

* 200 W surge power capability.

* High efficiency.

* Dual colour LED indicator.

* Protection: Input – battery low alarm/shut down, over voltage, polarity.

* Output – short circuit, over load, over temperature.

* Free air convection cooling.

* Low cost, high reliability.

* 1 year warranty.

Using high-frequency circuit topology, A300-100 is lightweight and has efficiency up to 90%. The design complies with global safety and EMC certificates and is suitable for powering many kinds of consumer electronics, home appliances, office and portable equipment, lighting equipment in vehicles, yachts, and mobile homes.
