Alpha Technologies Launches New Line of ±190Vdc Power Converters

Alpha Technologies Ltd. has announced its next generation Cordex HP LPS36, a compact, modular dc-dc up-converter system designed for powering distributed communication networks using ±190Vdc (RFT-V circuit) over an existing copper network. It features modular, high efficiency, quad output converter modules along with an intelligent controller. In addition, the company launched the Alpha SR-12190, a compact dc-dc down-converter that transforms ±190Vdc into 12Vdc

Applications include powering DSLAMs as well as the Optical Network Terminals (ONT) in FTTH Networks. The Cordex HP LPS36 can be installed in the Central Office or in a remote OSP cabinet. Line powering uses the CO or RT backup power system as the source, eliminating the need for AC utility or battery backup at the remote site, thus reducing truck rolls and operating expenses. Unlike conventional line power systems, the Cordex HP LPS36 combines the industry's best density and converter efficiency, with simplified installation and ease of use.

"The Cordex HP LPS36 is a breakthrough product," said Mourad Chergui, Product Manager -- DC Products at Alpha Technologies. "It offers greater than 50% more density than the present generation of products, and it is truly environmentally friendly. Besides eliminating the need for batteries at the customer's premises, the LPS36 generates nearly 50% less wasted energy than today's products."

The Alpha SR-12190 is a compact dc-dc down-converter that transforms ±190Vdc into 12Vdc for powering the ONT in a FTTH network. Designed for outdoor environments, the compact, self-enclosed design is ideal for mounting on the side of the house, nearby the ONT. It is equipped with a built-in capacitor to ensure continuous operation, even during brief electrical surges. Unlike other down-converters, the SR-12190 provides a 12V output designed specifically for powering ONTs.

"The Alpha SR-12190 is the only down-converter on the market that addresses the Single Family FTTH application," said Chergui. "It converts ±190Vdc to 12 volts to power the ONT, and does so in a very compact package that homeowners welcome."
