Delta unveils new 2.4 kW telecon rectifier with world-leading power density

Espoo, Finland, February 3, 2009 – Delta announced it has launched its new DPR 2400B-48 rectifier series, which offers the world’s leading shelf power density as high as 35 W / inch3. A single rack unit can also host up to 6 rectifier modules with a total installed power of up to 14.4kW.

“With the new series we can provide at least 20% more power in one shelf than today’s industry standard,” said Hans-Peter Glauser, Global Product Manager at Delta Energy Solutions Business Group. “The value can be even higher, as the complete electromagnetic compliance (EMC) and AC overvoltage protection are already built in the product.”

“The 2.4kW rectifier takes up to 50% less rack space and weighs up to 25% less compared to similar products on the market. In addition to its savings in energy consumption with greater than 94 % efficiency, the direct and indirect savings in materials and transportation reduce its environmental footprint—as well as freight bills. Moreover, the space savings, such as for our OutD solutions, leaves more room for customers’ own equipment installations,” said Albert Chang, Sr. Vice President and General Manager of Delta Energy Solutions Business Group.

Power density specifies how much power is packed into a single unit of volume. It is essential in electronic devices as it defines the product’s current flow in relation to size. Thanks to innovative and economical construction, the DPR 2400B-48 series rectifiers are significantly lighter and smaller than existing products.

This product will be available in the first quarter of 2009.

* Telecom power systems secure telecommunication services in case of power interruptions or fluctuations. The essential parts of the system are rectifiers, batteries and a power system controller. The rectifier converts alternating current (AC) to direct current (DC) and provides the power necessary to charge the batteries. The power system controller monitors and controls the entire system and site power infrastructure, maximizes battery life, supports energy saving and informs the operator of maintenance needs.
