Analog Transducer supports frequency voltage signals.
2013-07-02 14:30:52| Industrial Newsroom - All News for Today
Featuring 6.2 mm thick housing, MINI Analog Transducer converts measured signals into linear current or voltage signal. Common types of inputs include dry relay contacts, NAMUR sensors, NPN and PNP signals. Hot-swappable signal conditioning slices clip onto powering T-bus connector without removing bus bars or bridging. Offering dip-switch programmable setup, transducer provides power circuit range of 9.6–30 Vdc and transmission error of 0.1%. This story is related to the following:Watt Voltage Transducers |

400 MHz Ovenized Voltage Controlled SAW Oscillator
2013-07-02 11:15:15| rfglobalnet Products
This ovenized voltage controlled SAW oscillator (VCSO) is extremely effective and reliable in applications involving use of analog signal processing, such as radar, communications, and electronic warfare (EW). Addition of a micro-oven to the design yields superior temperature stability (just +/- 10ppm over temperature range -40C to 85C). Specific emphasis on low phase noise, from the start of the design process, has led to a SAW oscillator of superior performance and quality.

AVO Training Institute - Circuit Breaker Maintenance (Medium Voltage)
2013-06-27 18:08:00| Transmission & Distribution World
Unlike a low-voltage breaker, medium-voltage breakers rated at 1 kV or higher rely on external controls to operate effectively. That means technicians have more components to test and maintain to ensure a 3 to 5 cycle operating time. Failure of one of these breakers can cause catastrophic damage to other equipment and is extremely hazardous to nearby personnel. With safe and proper maintenance, technicians can ensure that tripping operations execute as required for equipment protection. In addition to improving electrical system reliability, well maintained circuit breakers also minimize the arc flash hazard energy levels that technicians can be exposed to during a fault. Location Various Locations United States See map: Google Maps Course Duration: 3.5 days Credits: 2.8 CEUs Level of Involvement: Hands-on Schedule: 8:00am - 4:30pm, the final day ends at 12:00pm Locations: Dallas, TX; Valley Forge, PA Course Number: 300 Tuition USD: $ 1440 Unlike a low-voltage breaker, medium-voltage breakers rated at 1 kV or higher rely on external controls to operate effectively.
