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