They include input voltage and frequency, appearance and dimensions, operating temperature and humidity, input AC socket, overall efficiency, standby power consumption, output voltage, output current, peak load, protection (including OCP/OVP/OTP), various EMC. Commercial AC power distributed from power plants cannot be supplied directly to the ICs and other electronic components built into electronic devices in automated office and factory equipment without destroying the components due to the high voltage of commercial AC power. This reference design showcases three non-isolated AC/DC power supply topologies for line-powered applications such as residential circuit interrupters, circuit breakers, home automation equipment and appliances for < 100 mA. It is required to connect a fuse to the L wire (the live wire) at the input end to meet the safety specifications. NĀ°714/2009 during November and December 2013 aiming at exchanging views on the challenges and key issues.
