With a 7-slot skewed armature design, the Pittman “Series 8000” brush-commutated DC motors from AMETEK minimize magnetic cogging (or reluctance torque). The motors are available in three lengths (2.070 in., 2.195 in., and 2.445 in.) and can achieve peak torques up to 16.8 oz-in and speeds up to 9020 RPM at continuous torque.
Featuring an IP67 rating, the PWS-8033M handheld computer from Advantech is resistant against dirt, dust, and complete immersion in under 1.2 m of water. The computer includes an XScale PXA270 624 Mhz processor with 3.7” transflective VGA TFT LCD, GPS, 802.11 WiFi, and a built-in Bluetooth. It has an operating temperature of -20°C to 60°C
SEOUL, South Korea — North Korea said Monday it will closely watch the international response to South Korea's planned satellite launch after Pyongyang was brought before the U.N. Security Council for what it said was a similar move. South Korea is aiming to launch a satellite into space from its own soil for the first time as early as next week.
Bel Power has added 20 A, 40 A, 50 A, 60 A, and 80 A Power SIP modules to its non-isolated DC/DC converter portfolio. These Power SIP modules operate at efficiencies of up to 94 power over a wide input range of 4.5 V to 13.8 V, and wide output voltage trim range of
The United States is taking steps to counter a new delay in the arrival of swine flu vaccine, hunting factories that can get more of the precious liquid into syringes faster. Dr. Robin Robinson, who is in charge of vaccine procurement for the Department of Health and Human Services, says he's trying to bring additional manufacturing online for the packaging step that has emerged as a logjam.
Long-range, low-cost wireless Internet could soon be delivered using radio spectrum once reserved for use by TV stations. TV stations have traditionally broadcast over lower frequencies that carry information longer distances. However, with the ongoing transition from analog to digital broadcasts, more unused frequencies are opening up than ever.
Apple Inc is investigating media reports that one or more of the company's iPhones have exploded in Europe, a European Commission spokeswoman said on Tuesday. The spokeswoman for the EU executive, which oversees the safety of consumer products sold in the 27-country bloc, said Apple had
With an 8:1 input voltage range of 18 V to 135 V, the IQ64 family of half brick dc/dc converters from SynQor purportedly doubles the existing 4:1 input ratio standard. The converters achieve up to 90 percent efficiency at full load. The half-brick format is comprised of nine output voltages, including 1.8 V, 3.3 V, 5 V, 12 V, 15 V, 24 V, 28 V, 40 V, and 48 V.
Heavy subsidies shelled out by telecom operators around the world to lure consumers to buy an Apple iPhone have done nothing to increase profits, and have even dented them in some cases, a research report showed on Monday.
Consuming less than 0.5 W standby power, with typical efficiencies in excess of 90 percent, the Mean Well GS220 series of 220 Watt AC-DC desktop power supplies from PowerGate meets Energy Star, EISA, and CEC Level V compliance. The power supplies consist of 5 single-output models with outputs ranging from 12 Vdc to 48 Vdc.
The Wireless Power Consortium released today the 0.95 technical specification for review by its members and announced the launch of prototype testing at a members' interoperability test to be held on 15-17 September, 2009. The Consortium also announced that it has chosen the logo “Qi” (pronounced “chee”, meaning “energy flow”) to represent the first international wireless power standard which brings new levels of convenience to power charging in consumer electronic devices.
In what’s sure to encourage conspiracy nuts worldwide, Britain has released the government's complete file on the "Rendlesham Forest Incident" of December 1980. The 191-page document was released as part of a larger cache of British “UFO files” covering the years 1981-1996. Lacking a concrete explanation, the government had nonetheless determined that the UFO spotted in Rendelsham posed no threat.
Martek Power introduced an active power factor correction and harmonic attenuation module with 100-W output power, extending the power range offered by the PFC family to 100 W to 1,000 W. The PF100 is a COTS unit for military and aerospace applications and is
Energy efficiency standards have typically concentrated on two ends of the spectrum – full load efficiency and standby power. As a result, popular PWM buck regulators available today demonstrate high efficiency at full load (>80%) levels and incorporate standby circuitry to comply with the <1W and lower initiatives. Improved efficiency at all operating points is an important concern in the design of next generation “green” products.
Featuring interchangeable AC input clips, the PSAA20R adapter series from Phihong purportedly enables widespread compatibility. Available in single 12 V, 24 V, and 48 V outputs, the series allows for the use of a single part number. The adapters feature a maximum no-load power draw of 0.3 W and an average operating efficiency of greater than 81 percent.
