The CPC1968 is a single-pole normally open (1-Form-A) solid-state power relay rated for up to 5A continuous load current with a 5°C/W heat sink. The output is constructed with MOSFET switches and photovoltaic die, while the input utilizes a highly efficient GaAIAs infrared LED to provide the optically coupled control.
People use their GPS apps, cameras, and mobile internet to navigate strange cities in search of good coffee, record "selfie" commentary while they wait in line, and upload their videos directly to social media sites while they sip their latte. But no amount of high-tech savvy can save a well-loved device from dying when its battery is drained.
International Rectifier introduced the IRAM630-1562F Intelligent Power Module (IPM) featuring Power Factor Correction (PFC) and inverter stage. The new IPM shrinks and simplifies design of energy-efficient appliance and light industrial motor drive applications including air conditioners and washing machines.
Researchers report that wood-biochar supercapacitors can produce as much power as today’s activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts. The report appears in the journal Electrochimica Acta.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a novel method for measuring laser power by reflecting the light off a mirrored scale, which behaves as a force detector. Although it may sound odd, the technique is promising as a simpler, faster, less costly and more portable alternative...

Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges. These are just two of the possibilities raised by a novel supercapacitor design invented by material scientists at Vanderbilt University that is described in a paper published in the Oct. 22 issue of the journal Scientific Reports.
RFMW, Ltd. announces design and sales support for Scintera Networks' SC1894 radio frequency power amplifier linearizer (RFPAL). As power amplifiers are driven into saturation they increase in both efficiency and distortion. The SC1894 injects a correction signal at the input of the PA in order to minimize distortion at the output of the PA.
