ABB Power Factor controller RVC

ABB Power Factor controller RVC

DESCRIPTION

RVC has become synonymous with automatic capacitor  bank controller in many markets worldwide thanks to  its distinct design, ease of use, reliability and versatile  functions.

Powerful features

•  Common range for a broad network voltages from 100V to  440V. 

•  Measurement and display of key parameters like voltage,  current, power factor, THDV and THDI. 

•  Fully programmable switching sequence. 

•  1A or 5A current input. 

•  Easy commissioning. 

•  Complete auto set-up (starting current-C/k, type of switching  sequence, phase shift, special connections).

•  Easy to use thanks to a user-friendly interface and ease of  access to parameters for manual setting. 

•  Highly efficient switching strategy combining integral, direct and  circular switching thereby allowing:  

• to control the cos j in presence of rapidly varying loads,  

• to reduce the number of switching,  

• to avoid unnecessary intermediary switchings, 

• to increase the lifetime of the capacitors and contactors.  

•  Suitable for hot environments due to maximum ambient  temperature rating of 70°C. 

•  Not affected by harmonics. 

•  Overvoltage / undervoltage protection and protections against  harmonic distortion (THDV). 

•  Alarm : an alarm contact is opened when any of these  conditions are reached: 

• the target cos j is not reached within 6 minutes after all  outputs have been switched on,  

• the internal temperature of the RVC rises above 85°C, 

• overvoltage / undervoltage limits are reached,  

• the power supply is out of range, 

• the THDV exceeds the limits.
