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
