Compact structure Compact, lightweight and high panel installationdensity Setting unit (option) Display of various parameters, voltage/current / power and change of the feedback system arepossible. Options The options of heater disconnection alarmfunction and current limit function are available. Various protections functions built-in The thyristor element is protected by melting o f the rapid fuse for short-circuit of load, and b y Phase-angle firing/zero-cross firing gate-off for over-current. For models with acooling fan built-in, alarm is activated and outputis stopped for abnormal heat-sink temperature. The phase-angle firing system and thezero-cross firing system are selectable. The running by the phase-angle firing system at theinitial stage and by the zero-cross firing systemat the normal stage is possible. Self-diagnosis function built-in Zero-cross firing system The self-diagnosis function is built in fo r With the delta-sigma modulation, which controlsevery 1 cycle, the fine control like thephase-angle firing system is possible. abnormal operation, abnormal thyristor elementand abnormal power supply. > 1
