»  Blocking of defective steps,
»  Wide Voltage sensing (90-500V AC) suitable for HT Application
»  Fully automatic detection of step sizes and VAR based compensation
»  Integrated under-voltage and over-voltage release and auto reset
»  Very low starting current of just 15mA even on either x/1A or x/5A path
»  Indication of PF-reading upto third decimal place, eg. “0.996”
»  Special resolution management for fine tuning of compensation
»  Special function possible to avoid leading power factor condition
»  THD monitoring and facility for programming trip function
»  Automatic detection of phase error
correction, possible auto correction
»  Storage of multiple alarm conditions
»  Totally secure and tamper proof operation
»  Manages steps of equal rating for even wear and tear
»  Compensates the reactive power needs at the fundamental frequency
»  Suitable for either x/1A or x/5A current path
»  Measurement and display of Voltage, Current, KVA, KW, KVAR, PF, COSφ, Individual harmonics of Voltage from 3rd to 15th level, ∆Q (required KVAR to target) number of hours on,
»  Operating cycles per step, average PF, rating per step in KVAR,
»  percentage of percent rating compared to initial nominal rating
»  Under & Over Voltage Protection
»  Under / Over Compensation
»  % THD Level trip
»  Low voltage switch-off against
chattering of contactors - Over voltage
»  Over temperature switch-off
»  Recognition of defective capacitors
»  Alarming, when target of regulation cannot be reached - Signalling of the need for maintenance
»  Fan control
»  Configurable Switching topologies
»  Best-Fit: starting with the biggest exits
»  LIFO: last in-first out
»  Combifilter: Best-Fit, with more connected power of odd exits
»  Progressive: all required exits are switched in quasi one operation
»  RS 485 on MODBUS optional
