Multi-zone Power Control System - REVO-PC 2PH

Ideal for: multi-zone applications where the need to closely manage your process and reduce your energy costs are required
8, 16 & 24 Channels / 1, 2 & 3 Phase Control

 

CD Automation's innovative multizone power management system, the REVO-PC, was designed specifically to manage multizone systems.

This powerful unit works in conjunction with REVO-S solid state relays and has an easy to implement algorithm that minimises power overshoot, maximises power factor, reduces harmonics and flicker by synchronising loads, as well as limiting maximum power demand so that maximum demand supply contracts are not exceeded.

Overview

Benefits include:

  • Each loop's process information is managed independently:
    - Calculation of instant current and RMS Voltage, Current and Power
    - Calculation of load resistance with Heater Break Alarm
    - Modbus Master, Modbus slave, Profilbus DP, Modbus/TCP, Can-Open

  • Elimination of power overshoot (see graph above)
  • Power factor close to one due to zero crossing firing
  • REVO-PC keeps your instantaneous power within the limit of your electricity supply contract
  • Prevents increases in energy supply tariffs imposed by your electricity supplier
  • Quick return on your investment.

 

This powerful unit with its high performance micro can drive simple thyristor unit REVO S with Zero Crossing firing. By using the REVO PC, simple thyristor units can be used reducing the overall financial investment.

  • Simultaneous fast full wave control of
    8-16-24 REVO S - 1PH
    8-16-24 REVO S - 2PH/3PH for 3 phase loads
    8-16-24 REVO S - 2PH/3PH for 3 phase load with current calculation for each phase
  • Simultaneous fast full wave control of
    8-16-24 CD3000E-2PH; Multidrive-2PH
    8-16-24 CD3000E-3PH; Multidrive-3PH

Technical Information

 

TYPICAL APPLICATION WITH 8, 16 OR 24 SINGLE PHASE LOADS


EASY START-UP OF REVO-PC

  • Set the operating current of the heater zone
  • Set the total power limit
  • Set the power of each zone

 

 

 

   

SYNCHRONIZATION

On all controlled zones, the live predictive synchronization is automatic resulting in superior performance:

  • Total current is equal to a sinusoidal waveform
  • Power Factor >0.9
  • Instantaneous current close to average value
  • Cancellation of harmonics
  • Power saving by harmonic reduction
  • Flickering effect removed


Synchronization selection is available for normal resistive loads of short wave infrared.


     
 
     

SMART POWER LIMITATION

  • Smart power limitation works together with synchronization. If this function is enabled, REVO-PC makes a live calculation of power at each period and generates the output values for the next period.
  • If the calculated power is below the power limit value, the previous values remain with each channel using full power.
  • If the power is above the power limit value, the setpoint of each channel is reduced proportionally to restrict power overshoot. This function significantly reduces disturbances on the main network compared to a full power system, preventing any increase in energy tariffs imposed by the electricity supplier.
  • This function can be activated/deactivated and the limit value changed at any time.
