NetSure 731 A41 Series Subrack Embedded Telecom DC Power System

Product Description

Introduction

The NetSure 731 A41 series is a mature subrack-style embedded DC power system launched by Vertiv (formerly Emerson), specially engineered for network frame systems and various telecom facilities. It supports 220V single-phase and 380-415V three-phase dual AC input, with an ultra-wide operating voltage range of 85~305V. The system delivers stable single 48V DC output, with an adjustable voltage range from -42.3V to -57.6V and a maximum output current of 400A. It features a power factor up to 0.99 and overall efficiency over 90%. Adopting modular design, intelligent fan cooling and multi-level protection technology, this series includes multiple sub-models (S7/S8/S9/S10/S11) to meet differentiated application demands. With compact structure, front maintenance design and reliable long-term operation capability, it is widely adopted in communication base stations, indoor machine rooms and FTTX network power distribution projects worldwide.

Key Features

Dual Input Compatibility: Supports 220V single-phase & 380-415V three-phase AC input, with 85~305V wide working range, adapting to complex power grids and generator power supply.

High-Current Output: Max 400A DC output provides sufficient power reserve for medium and large telecom equipment clusters.

Excellent Electrical Performance: Power factor reaches 0.99, and system efficiency exceeds 90%, effectively reducing reactive power loss and daily energy consumption.

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

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

Intelligent Heat Dissipation: Equipped with speed-adjustable fans that automatically regulate rotation speed based on load and temperature, lowering noise and extending component service life.

Full-Range Protection: Integrated overvoltage, overcurrent, short-circuit, overtemperature and multi-stage lightning protection, effectively resisting surge and abnormal voltage damage.

Soft Start Function: Walk-in soft start avoids instantaneous current impact on front-end power equipment, enhancing the stability of the entire power grid.

Multiple Model Options: Rich sub-models (S7/S8/S9/S10/S11) for selection, covering diversified configuration and scene requirements.
