Rosenberg has recently expanded its high-efficiency E-Series backward-curved impellers to now include sizes from 12.4 to 22 inches with either AC or EC motors. The unique airfoil blade impeller increases energy efficiency by up to 4% and reduces noise by 3 to 5 dB(A). Recommended for computer room air conditioning and air handling (CRAC/CRAH), or energy recovery. … [Read more...]
New PWM Controller for Fans Released
SANYO DENKI has recently released their “San Ace PWM controller”, which controls fan speed through PWM. This contributes to reduced system power consumption and the fan noise. Up to four PWM-input fans can be connected to each controller, without requiring a costly function generator. The controller can be powered by the fan power supply at rated voltages of 12, 24, and 48 … [Read more...]
High Temperature Analogue and Mixed Signal Electronics May Become Silicon Carbide-Based
(May 24, 2016) Recently, SiC (Silicon carbide) has been recognized as a material that can be “used for small signal electronics – such as analogue and mixed-signal devices – making possible the locating of monitoring and control circuitry much closer to heat sources” in the electronics industry, according to NewElectronics.co.uk. “Research groups have been exploring various … [Read more...]
New Type of Graphene Could Increase Processor Clock Speeds
(May 19, 2016) Recently, scientists from the Moscow Institute of Physics and Technology (MIPT), the Institute of Physics and Technology RAS, and Tohoku University (Japan), have developed a new type of graphene-based transistor, whose modeling demonstrates that it has ultralow power consumption compared with other similar transistor devices. The newly proposed design was for a … [Read more...]
Recall On Overheating Laptop Battery Packs
(March 31, 2016) Toshiba recently issued a voluntary recall on its laptop battery packs for potential burn and fire hazards from overheating. According to ConsumerReports.org, the battery packs were manufactured by Panasonic and installed in 39 of Toshiba’s laptop models, including the “Mini Notebook, Portégé, Satellite, Satellite Pro, and Tecra lines of PCs”. But “any laptop … [Read more...]
