MULTI-CHANNEL POWER SUPPLY CONTROLLER

摘要

PURPOSE: A multichannel power supply controller is provided to convert a control mode into a phase angle control mode or a zero crossing control mode if necessary, thereby enabling utilization of the multichannel power supply controller with a single phase and a three-phase. CONSTITUTION: A control board(200) is a card edge type. A phase detection board detects a three-phase phase signal from a main power source. One or more control boards and a single phase detection board are mounted on a card slot of a multichannel control unit(100). The multichannel control unit separately or integrally controls each control board according to a control signal inputted from an external controller. A power control unit(400) controls the size of power supplied to a load by the control board.
