Description

3-PHASE POWER CONTROLLER (200A)

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
