DongAh Elecomm, a leading provider of power supplies for telecom, industrial and medical markets, introduces its new 288W LOPU-A4L rectifier from the Cheshire™ Series designed to support expansive growth in small cell 4G/LTE wireless/telecom base stations and network equipment.

DongAh Elecomm has extensive experience in the wireless/telecom market, having deployed more than 200,000 small cell systems internationally. Small cells are being added globally to increase capacity in hot spots with high user demand and to fill in areas not covered by a macro network. They also improve network performance and service quality by offloading demand from traditional base stations, reducing both cost and power requirements. By 2017, small cells are expected to carry nearly all mobile network data traffic. By 2018, it’s predicted that some 11 million small cells will be in use, a roughly five-fold expansion since 2013.

The LOPU-A4L rectifier module provides high efficiency network power at competitive pricing, with quick and easy installation, a small footprint and inconspicuous IP65-rated enclosure for outdoor applications. The unit utilizes free-air convection cooling that requires no fans. It is designed to meet UL® and Telcordia Technologies Industry Standards with high reliability.

LOPU-A4L Key Features:

• High efficiency
• Suitable enclosure for outdoor applications
• Discreet appearance
• Designed for high reliability
• Free air convection cooling; no fans
• Easy installation with quick-mount brackets
• International Safety Approvals (pending)

Other products in DongAh’s Cheshire Series of small cell power systems include:

• KLTE-413 – 53.3VDC / 13A Output
• KLTE-430D– 53.3VDC / 30A Output
• NORS-415– 54.0VDC / 15A Output
• LORS-415L– 54.0VDC / 15A Output
• SRRH-4805, SRRH-4805-RECR04D Compact Power System

The DongAh CWRS-4150A modular power system is currently being deployed to major telecommunication companies in the US and Europe in support of this expansive growth. The CWRS-4150A provides up to 8KW of power in a compact 2U shelf and is NEBS certified for Zone 4 seismic activity.

Our SRRH-4805 was used for the LTE deployment in Korea, which is noted for having the best IT infrastructure in the world. The SRRH-4805 module provides outdoor power for next generation 4G/LTE picocell networks. It can be deployed at a lower cost than other power systems used to enhance LTE deployments.

The ITU says that the proportion of households with Internet access in developing countries went from 12% in 2008 to 28% in 2013, “a remarkable 18% compound annual growth rate.” South Korea has been named the most tech-developed country for the third year in a row. Northern European countries (Sweden, Iceland, Denmark, Finland and Norway, in that order) make up the the next five ICT leaders. The UK moves up three notches to number-eight; the U.S. drops down one position to number 17.

Additional figures from the ITU report include:

• 250 million additional people came online in 2012
• Mobile broadband is now more affordable than fixed broadband
• Almost the whole world is now within reach of mobile cellular service
• 30% of the world’s young population are ‘digital natives’ (15- to 24-yr-olds with 5 or more years of online experience)
• Broadband is getting faster; 2Mbps now most popular basic package

DongAh Elecomm, a leading provider of power supplies for telecom, industrial and medical markets, today announced a high efficiency NESpace™ Energy-Saving Power Shelf that offers up to 96% efficiency and a loss reduction of greater than 50%. NESpace significantly reduces energy consumption and loss over standard power supplies. Easy installation and maintenance make it ideal for power-hungry datacom and telecom applications such as cellular base stations, ADSL equipment and fiber nodes, as well as central offices.

Because DC power-based systems are the major energy user for most telecom service providers, increased efficiency can significantly improve the bottom line. The growing demand for high-speed and mobile communications platforms has fueled enormous growth of broadband and wireless networks worldwide. The accompanying increase in energy consumption is a large portion of operating expenses for telecom providers. Energy optimization results in a significant reduction in wasted energy, heat and CO₂ emissions.

Housed in a compact 19” 2RU-high shelf, NESpace provides 8KW with four hot pluggable 37A rectifier modules. The power system is designed with battery management systems for truly redundant operation in indoor and outdoor environments. Software integration allows remote monitoring and control, and hot plug-in switchmode rectifiers allow for easy system upgrades.

 NESpace™ Key Features:

• Up to 96% efficiency
• Energy saving operation
• 19” Rack-mount unit
• Hot-swappable
• Rectifier module DSP control
• Constant electric power control
• Automatic battery charging (floating mode with temperature compensation)
• Temperature compensated charge voltage for increased battery life
• Control module for full alarms and monitoring

DongAh Elecomm designs, manufactures and markets a full line of high efficiency, high density AC/DC power supply products and power systems for the telecom, industrial and medical markets. DongAh develops product lines with extremely flexible architecture and can rapidly modify standard power supply products to meet the needs of customers who require non-standard output voltages.

• Is there a power supply already available that meets your needs?
• Does the cost of the end application justify the added expense?
• Are off-the-shelf semiconductors required by your design supported by applications engineering staff and software design tools? Using the wrong part or circuit can become an expensive mistake once it goes into production.
• Do you have the internal resources necessary to design, build and test your own? (Click here to read 14 key considerations.)

DongAh Elecomm began working with Siemens Medical Solutions (US) in 2003 with the BSRP. Our business with SUSKO began in 2005 with the G40 AC and DC power supplies, and we have added new ones throughout the years. The power supplies have evolved to a design that consolidates the AC and DC products into one power supply: the X300(VE) and X150(VE). As part of our efforts on behalf of SUSKO, we developed a dedicated manufacturing line, an on-line process management system and paperless functional testing with our Automatic Inspection System for accurate and fast measurement. Visit our Medical Power Solutions page for more of the story.

DongAh’s ability to meet customer requirements while improving processes, quality and techniques demonstrates our dedication to our customers and our commitment to excellence.
