The RAC10-K/277 series are multipurpose 10 watt AC/DC power supplies for an extended mains input
from 80VAC up to 305VAC. These modules are designed to power on-board applications in automa-
tion, Industry 4.0, IoT, lighting and smart buildings worldwide. The efficiency is constant over a wide
load range and the standby power consumption is less than 0.3W. With universal input voltage cover-
ing 100/115/230/277VAC or 113-430VDC, fully protected single or dual outputs and EMC Class B
emissions compliance without any external components, these are one of the easiest to use modular
power solutions in the industry.

Ripple and Noise is the maximum peak-to-peak voltage value measured at the output with a 20MHz bandwidth, at rated line voltage
at full load and with a 0.1µF ceramic capacitor across output. Do not use scope ground lead to measure the output ripple and noise
