Thyristors power controller RP3

three-phase

The RP3 power controller is a contactless three-phase power energy electronic device which includes a thyristor connector and an electronic gate triggering system. (GTS). This power controller allows the control of the power delivered from a three-phase voltage source to an electrical energy load in function of the control signal input. The RP3 power controller is destined for three-phase actuators with resistance or resistance-inductance loads in control systems and automatic temperature control. The application area of RP3 power controllers comprises: -electrical furnaces and drying constructions, particularly industrial tunnels and belt- type furnaces, furnaces for annealing and hard soldering, crucible furnaces and smelters, furnaces for hardening in salt baths, -devices of mechanical engineering, aggregates and extruding presses for plastics, devices, for winding and tempering of springs, spot welding and seam welders, -production of glass and glazing, installations and devices for drying in infrared and ultraviolet radiation, ladles for glass melt and heating of feeding devices, furnaces for glass forming, -chemical and petroleum industries, facing heaters of tube installations, preheating installations. KINDS OF CONTROL -On-off control. -Chopper control: -fast cycle - fi,max » 1 Hz, -slow cycle - fi,max » 0.1 Hz. -Phase control. ADDITIONAL FUNCTIONS -Load current limitation -Delay of soft start tripping type -Control of the initial gating angle value -Control of the input line amplification -Supervising and signaling of the current in the load circuit, output U= f(lo)
