NetSure 731 A41 Series Subrack Embedded Telecom DC Power System
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.
