NetSure 731 A41-S8 Vertiv/Emerson Telecom DC Power System

Product Description

Introduction

The NetSure 731 A41-S8 is a high-performance three-phase telecom DC power system developed by Vertiv (Emerson), designed for large-scale network frame systems and high-load communication facilities. It adopts 380~415V three-phase AC input, and converts to stable 48V DC power with a maximum output current of 400A. The adjustable DC voltage ranges from -42.3V to -57.6V, which adapts to various telecom devices and battery charging requirements. This system features a power factor up to 0.99 and conversion efficiency over 90%. Built with modular structure, intelligent fan speed regulation and full-range protection circuits, it also supports multi-interface remote monitoring and hot-swap maintenance. With solid build and reliable performance, it complies with CE and ROHS standards, and is widely applied in large communication base stations, central machine rooms and data center power distribution projects.

Key Features

Three-Phase Wide Input: Supports 380~415V three-phase AC input, perfectly matching industrial and large telecom power supply standards, and operates stably under fluctuating grid voltage.

High-Current Output: Max 400A DC output meets the power demand of large-scale equipment clusters and high-load communication scenarios.

Superior Electrical Performance: Power factor reaches 0.99 and conversion efficiency exceeds 90%, effectively reducing reactive power loss and long-term operating costs.

Adjustable DC Voltage: Output voltage adjustable between -42.3V and -57.6V, compatible with different types of communication equipment and storage batteries.

Modular Hot-Swap Design: Rectifier and monitoring modules support hot plugging. Maintenance and replacement can be done without system shutdown to avoid service interruption.

Intelligent Heat Dissipation: Equipped with intelligent speed-adjustable fans, which automatically adjust rotating speed according to load and temperature, lowering noise and extending service life.

Comprehensive Protection: Integrated overvoltage, overcurrent, short-circuit and overtemperature protection, plus multi-level lightning protection to defend against surge damage.

Soft Start Function: Walk-in soft start design avoids impact on front-end power equipment during startup, protecting the entire power grid system.

Standard Certification: Complies with CE and ROHS international standards, safe and reliable for global project deployment.
