从China供应商批发进口48v 2900w Rectifier Module Emerson R48-2900u — FOB条款

The Emerson R48-2900U is a 48V DC rectifier module delivering 60A at 2900W, engineered for telecom base station power systems such as the 701 A30 configuration. It converts AC input (220V single-phase or 380V three-phase) to a regulated -42 to -58V DC output, supporting critical infrastructure for 3G, 4G, and 5G networks. The module integrates hot-swap capability and front-access design for maintenance in live systems, with PWM modulation and separate-excited switching power supply for stable operation.

Housed in a steel case with PCB assembly, this rectifier is UL, CE, RoHS, and FCC certified, meeting global safety and electromagnetic compatibility standards. It supports terminal power distribution with configurable circuit breakers for high or low priority loads, and includes optional battery low-voltage disconnect to protect connected batteries. Typical telecom rectifiers in this class operate at 85-90% efficiency, with input power factor correction and overcurrent protection as standard features.

This module is deployed in telecom subracks where up to 9.6kW of DC power is required, allowing scalable expansion as network demands grow. Buyers typically source these for base station upgrades, remote off-grid sites, or redundant power systems. The unit weighs 3.5kg with dimensions of 132 x 85 x 287mm, packaged as 1 piece per box, and ships worldwide via FedEx, UPS, or DHL within 3-5 working days after payment confirmation.

Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd. operates from Room B813, No.61 Yejin Avenue in Wuhan, Hubei Province, China. The company is classified under the harbor trust tier, indicating a baseline level of verified business information. Its address places it in a commercial district of Wuhan, a major industrial hub in central China known for electronics and machinery manufacturing.

The supplier specializes in electronic components and power systems, including rectifier modules like the Emerson R48-2900U. While its current response rate is listed as 0.00 with no average response hours recorded, the company’s focus on telecom power equipment suggests experience in B2B transactions for infrastructure projects. Buyers should directly confirm communication channels and support capabilities before placing orders.
