RP3
3-phase power controller

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)
• Supervising of the radiator temperature
• Signalling of the fuse damage
• Signalling of the incorrect phase sequence
• Signalling of overload
• Relay outputs
