  • Power Switching
    Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. These circuits can function as pulse-width modulators or switches to provide variable power to specified loads. Power modulators electronically control

  • Holding loads with power-off brakes
    Q. What's the difference between stopping dynamically and holding a load with power-off brakes? How do I correctly size a power-off brake? A. With dynamic stopping the brake must absorb the kinetic energy built up by the inertial loads. In such instances the brake transfers that energy, causing

  • No Load Power Consumption and Efficiency of External Power Supplies
    This document aims to give a summary of the requirements of the various bodies which currently define and regulate the no load power consumption and active mode (when a load is connected to the output) efficiency of XP's external power supplies. Two important reasons for wanting to control

  • Line-interactive Uninterruptible Power Supply (UPS)
    Line-interactive uninterruptible power supplies (UPS) work in parallel with conditioned input AC power to supply power to the load (boosting or bucking), and only handle the full load power when the AC input power fails. Line-interactive uninterruptible power supplies (UPS) provide protection from
