Plant aims to recycle Li-ion batteries
AEA Technology is to set up a GBP 2 million facility in Scotland to develop world-beating technology for the recycling of lithium-ion batteries.
It was rated for 700W of output power at 12V DC.
The power supply delivered an outstanding 87% efficiency from 50 to 100% of rated output power.
Also noteworthy was the unit's 80% efficiency at 20% of rated output power, a typical operating point for idle server resources.
With this performance ColdWatt is leading the industry in efficiency across the operating range, especially under the increasingly important light load condition.
EPRI Solutions and ColdWatt are both concerned with the environmental and operational impact of energy efficiency in enterprise IT equipment.
"Savvy IT professionals across the industry now realise that there are big savings linked to the efficiency of power supplies in data centre equipment", said Dr Arshad Mansoor, Vice President, Power Delivery Business Unit, EPRI Solutions.
"We applaud companies like ColdWatt who are committed to innovating energy efficient technologies".
The efficiency of power conversion technology used in IT equipment plays a pivotal role in the amount of electricity consumed by the data centre.
"Energy losses associated with AC/DC power conversion in IT equipment is a significant opportunity to reduce data centre operating expenses and conserve energy", said Dan Artusi, Chairman and CEO of ColdWatt.
"We are delighted to have received an independent validation of our technology from EPRI Solutions".
