Engelking, Ideal Power, & be quiet! Announce Power Supply Efficiency DevelopmentsJanuary 27, 2008 by Jeff Shepard
Engelking Elektronik GmbH introduced a new generation of computer power supplies intended for industrial and professional applications. This product manages efficiencies in excess of 85%, meaning lower heat losses and high outputs with passive cooling. The cooling plate is made of aluminium which means that either cooling fins can be mounted or the unit can be directly flanged onto a housing case.
The U1-6300C is equipped with the usual PC-compatible outputs and has Power Factor Correction (PFC). The power input range is from 90-264Vac. As this is all packaged in a compact U1 form factor case and while the unit can be completely cooled over its case, it can find application where normal power supplies would not be suitable.
Ideal Power announced that it is now offering a range of CEC IV (California Energy Commission) compliant plugtop and desktop power supplies for companies that export products worldwide including the USA. The regulations require the power used in standby operation to be below a set level when unloaded: maximum energy consumption in standby must be 0.5W if the output is less than 10W and 0.75W if the output is between 10 and 250W.
Models available vary from 5 to 150W, and the majority of the supplies comply with EN60950, UL1310, CE marking and RoHS requirements. All units are available with universal ac input, short circuit, overvoltage and overcurrent protection and a wide range of input and output connectors.
be quiet! announced that the Electronic Power Research Institute (EPRI) has verified the new modular be quiet! Dark Power Pro power supplies with 450, 550 and 650W within the EPRI 80plus program.
Within 80plus validation EPRI figured out an efficiency of more than 80% for all be quiet! Dark Power Pro modular power supplies at 20, 50 and 100% load. In comparison to Europe the validation-process did use a line voltage of 115V instead of 230V for Europe. This increases the demands on power supply technology.
