  • Page 5: Application

    1. APPLICATION The RP3 power controller is a contactless three-phase power energy electronic device which includes a thyristor connector and an electronic gate triggering system. 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.

    Remarks concerning the operator safety: 1. General - The RP3 power controller is destined to co-operate with other devices. - Non-authorized removal of the required housing, inappropriate use, incorrect installation or operation creates the risk of injury to personnel or damage to equipment.
  • Page 7 EMC legisla- tion. 5. Operation - Installations including RP3 power controllers must be equipped with protection devices according to the corresponding standard and regulations for prevention of accidents. - After the power controller has been disconnected from the supply voltage, live components and power connections must not be touched immediately because capacitors can be charged.

    6. DESCRIPTION OF CONTROL TYPES 6.1. Control of ON-OFF type At the on-off control, the delivered power to the load is described by the following dependence: Where: Po - delivered power to the load, Xin - value of the input control signal. The power controller works in the semi-conductor relay mode.

    Runs of characteristic quantities for the impulse control are presented on the fig.6.3. The filling factor y is described by the following dependence:   Fig.6.3. Runs of characteristic quantities for the impulse control with variable pulse frequency. 6.3. Phase control At phase control, a continuous change of delivered power to the load occurs, it is realised by the change of the load current turning on angle in the function of the analog control signal.

  • Page 20: Limitation Of The Load Current

    6.4. Limitation of the load current If the current value in the load circuit exceeds the boundary value set by means of the „Limit” potentiometer, then the current limitation operates regardless of the control signal value. It is possible to assign it from an external potentiome- ter, p.
