85–300 VAC Input Voltage Digital Rectifier With High Efficiency And Power Density
1. Product Description
The R4830N2 is a digital rectifier with high efficiency and power
density. It converts 85–300 V AC input
voltage to 53.5 V DC output voltage. The output voltage can be
adjusted by the host. It performs comprehensive protection
functions, supports soft start, and produces low noise. With the
latest power monitoring technology, states of the rectifier and
load are monitored in real time. Multiple rectifiers can be
paralleled.
2. Key Features
