DCregulatedsingle-output

Description
AC input: 176 VAC – 280 VAC. DC output: 40 VDC – 60 VDC. Dimensions: 482 × 410 × 132 mm (19" 3U). Weight: 21 kg. Warranty: 2-year.

Overview
VT-220/48-200AS is a telecom-grade modular DC rectifier system designed for 19-inch rack installation. The modular architecture enables capacity scaling by adding or removing rectifier modules and integrates monitoring modules for system supervision. Intended for communication and industrial power applications, the system delivers load power and provides battery float and equalization currents under normal operation. Rectifiers support parallel operation and current sharing for redundancy and capacity expansion.
