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.
