96% High Efficiency Embedded Telecom DC Power System
,4U 19-Inch Rack Embedded DC Power System
,80-300VAC Ultra-Wide AC Input Telecom DC Power Supply
The Vertiv NetSure 731 A41-S7 (formerly E merso n brand) is a high-efficiency, single-output embedded DC power system with a standard 4U 19-inch rack dimension. It is specially designed for small FTTx OLT cabinets, indoor access network equipment, and compact unmanned communication sites.
With an ultra-wide 80~300VAC single-phase AC input, it converts alternating current into adjustable -42~-58VDC stable DC power (nominal 53.5VDC). The system supports flexible rectifier configuration and is equipped with an intelligent monitoring unit and a complete multi-level load shedding circuit, plus built-in full-range lightning protection on AC, DC, and signal terminals.
Featuring an ECO energy-saving mode and intelligent fan speed regulation, it achieves up to 96% conversion efficiency and is widely used for small-capacity communication equipment backup power worldwide.
- Standard 4U 19-inch rack size (483×390×178mm) with front full maintenance and dual-side wiring design for easy installation.
- Ultra-wide AC input range of 80~300VAC, 50/60Hz, offering excellent adaptability for unstable municipal grids and diesel generator power.
- Adjustable DC output of -42~-58VDC (default 53.5VDC), single output structure, PF ≥ 0.99 with low harmonic distortion.
- High-efficiency rectifier matching with peak conversion efficiency up to 96%; ECO sleep mode reduces idle power consumption.
- Hot-swappable rectifier module design allows replacement without shutting down the whole power system, minimizing site maintenance downtime.
- Built-in multi-stage BLVD/LLVD load shedding protection effectively extends the service life of lead-acid and lithium battery packs.
- Full lightning surge protection for AC input, DC output, and signal ports, compliant with telecom anti-surge standards.
- Intelligent temperature-controlled variable speed fan reduces running noise and prolongs fan service life.
- Rich communication ports: RS232 + dry contact alarm for remote data monitoring and fault alerts; CE certified.
- Wide operating temperature range of -40℃ ~ +70℃ for stable running under harsh high/low temperature cabinet environments.
