Green AC Appliances : ProblemLow AC Standby Power & Energy Star with Wireless Radio

AC appliances shall earn a Green label (e.g. Energy Star & IEC62301)for energy saving and low standby power consumptionStandby power standard scoring from 0.5W down to 0.03W

Infrared (IR) remote control easily achieve Energy Star low standby < 0.5WWireless radio is not easy. In standby, radio still consumes power

Wireless Receiving AC/DC power

Bluetooth 5 ~ 30 mA > 1W

Wi-Fi 70 ~ 150mA > 1W

LoRa 10 ~ 20mA > 1W

Infrared (IR) 0.3 ~ 1mA 0.3W

Our Key Technology - XsP AC Direct to DC Power with LDO for Green Standby

Conventional power supplies are not optimized for sub 100mA consumption in terms of energy efficiency and standby power.

With our novel technology, XsP Xtra Small Power (patent pending) supply wireless radio devices or IoT devices for < 50mA at the high efficiency, with no transformer/inductor and no switching element for good EMI

Technology Efficiency at sub 100mA Standby with Radio

XsP AC direct to DC 70% (at 50mA) 0.1W ~ 0.15W

Conventional SMPS flyback < 20% > 1W

Conventional SMPS buck < 40% > 0.5W

XsP Products AC Direct to DC Power with LDO for Green Standby
