Relay RNPP-301
Offer type: salePublished: 28.02.2015
The relay is a microprocessor-based digital device with a high degree of reliability and accuracy. Operational power is not required - the controlled voltage is simultaneously the supply voltage. The internal circuit of the relay is powered by three-phase capability even when one of the phases (if "zero")
Relay:
- separate control settings for min/max voltage;
- control of the correct phase sequence and the absence of their adhesion;
- control pornofanatic and the symmetry of the network voltage with adjustable setpoint on the phase imbalance;
- monitoring the status of the power contacts of the motor starter before and after the load;
- load shedding conditions arise for operation with the user-defined time delay (TCP);
- quality control voltage when switching off the load and its automatic reclosing (AR) after resetting voltage with a preset time AR - (ton);
- the time delay for Umin, which provides the offset from the short-term and/or starting undervoltage (Tmin);
- the choice of the control phase or line voltage;
- a separate indication for each type of failure of the mains voltage indication U network.
