  • Lowering the Limits for Ground-Fault Protection (.pdf)
    tripping can become a problem that worsens with the increased use of adjustable-speed drives. This paper discusses the sources of current flowing to ground that are not the result of a ground fault, and shows how a digital filter tuned to the fundamental component of ground-fault current can provide
  • A Digital Constant Current Power LED Driver
    the PIC12HV615 microcontroller (MCU). The increase the allowable current ripple to reduce the PIC12HV615 is an 8-pin MCU with many integrated inductor value. However, the +/- 20% limit is a rule of analog features. The LED driver circuit is a buck (step- thumb to minimize efficiency losses in the LED. You
  • Application: Hospital Bed Position Detection Sensor (.pdf)
    There are a large number of applications requiring the detection of end limit position, where electric shock can be a real concern. Hospital beds, for example, need end position limits when adjusting the bed position. Reed Sensors are ideal in this application because they reliably pass very low
  • Resistor Specifications and How to Interpret Them
    In electronic circuits, resistors are used to limit the amount of current flowing to a circuit, divide voltages, adjust signal levels and terminate transmission lines, among other applications. Without resistors other circuits or modules will not work as intended. These diverse uses mean
  • Application: Mobility Equipment & Hospital Beds - Reed Sensor
    There are a large number of applications requiring. the detection of end limit position, where electric shock can be a real concern. Hospital beds, for example, need end position limits when adjusting the bed position. Reed Sensors are ideal here because they reliably pass very low level voltages
  • FLOWgate TM: The Gate to Ultrasonic Gas Flow Measuring Devices
    FLOWgate TM. User management provides four different user groups ranging from guest to service. A scalable amount of information, data, and tools is accessible for these groups and the complexity can be adjusted according to your needs. In addition, FLOWgate TM offers the option of defining
