  • The RS-232/DALI Bridge Interface
    at lower power levels than standard magnetic ballasts. With the rise of digitally controlled ballasts, the need for devices that ?talk? to them has increased as well. This application note describes a very simple interface between the RS-232 serial port (available on almost all computers) and DALI, where
  • What is Inrush Current?
    When switching on solid state equipment such as computers, copiers, and electronic ballasts found in lighting systems, as well as magnetic devices like motors, drives, and core & coil ballasts, peak inrush currents can be several orders of magnitude greater than the circuit's steady state current
  • Power Factor
    Power Factor (pf) is the ratio of real power to total power. Real, or productive power, is the actual power used in a building, measured in kilowatts (kW). Reactive power generates the magnetic field for inductive loads such as motors, transformers, lighting ballasts, etc. Reactive power
