Product Overview
The R48-3000e3 converts standard AC supply voltages into a stable, adjustable -42 to -58 VDC output rated 3000 W with up to 62.5 A at -48 VDC. The module is designed for Vertiv NetSure DC power systems such as the NetSure 731 A412, where multiple rectifiers operate in parallel under a shared system controller.
Input is 200-250 VAC nominal with an allowed 85-300 VAC window at 45-65 Hz and a maximum draw of 22 A, with power factor above 0.99. Peak efficiency reaches 95.5%, cutting operating energy cost across the load profile of continuous telecom operation.
The module is rated for operation from -40 to +70 degC and measures 1.7 x 3.3 x 13.0 inches with a weight of 3 kg, matching standard 1U-height rectifier slots for straightforward replacement and expansion. Safety compliance is certified to EN 60950-1.
