The new technology is expected to contribute to the downsizing of power electronics equipment.

Key Points: 
  • The new technology is expected to contribute to the downsizing of power electronics equipment.
  • * According to Mitsubishi Electric research as of March 25, 2020
    Mitsubishi Electrics new integration technology enables the parasitic inductance of the switching current loop to be reduced to less than 1/10th that of conventional converters.
  • The technology leads to considerably smaller passive components, such as reactors for current smoothing, and capacitors, which take up much space in DC-DC converters.
  • In the effort to downsize power converters used in power electronic equipment, one of the main targets is reactors.

Fluke 710 mA Loop Valve Tester speeds assessments of HART smart control valves with built-in tests that ensure quick, reliable results

The new Fluke 710 mA Loop Valve Tester allows technicians to source the 4-20 mA signal while it interrogates HART data to collect critical information about the valve's position and status, providing quick checks of control valves while they are in place.

Key Points: 
  • The new Fluke 710 mA Loop Valve Tester allows technicians to source the 4-20 mA signal while it interrogates HART data to collect critical information about the valve's position and status, providing quick checks of control valves while they are in place.
  • With built-in test procedures and an intuitive interface, the Fluke 710 allows technicians to quickly and easily perform valve tests, while the valve test quick-check results provide at-a-glance diagnostics to make faster maintenance decisions.
  • In addition to positional information, the measured pressure delivered from the valve's internal I/P (which moves the valve) can be seen with the HART communication protocol.
  • Stepping the mA signal on the input to the valve in steps and evaluating the valves response to the mA input changes.
