Field of Application:

• For centralized power factor correction of inductive loads in power systems
• without or with a converter load under 20% of the total load

 
Principle:

• The power factor controller measures the reactive power present and, when deviations from the setpoint occur, it issues switching commands to contactors. These switch capacitor branches in or out depending on the requirements.
• For small power factor correction units the controller MODL CC is used.

 
Characteristics:

• Save energy costs, relieve connecting cables by the application of compact, reliable 4RY small power factor correction units
• Easy insatallation, small space requirements, ready for connection
  Type-tested switchgear assembly (TSK) according to EN 60439-1, IEC 439-1 for indoor installation
• Comprehensive range of types, various housing variants or base plates for use in customer`s at hand housings

Field of Application:

• Used in low-voltage power systems with low harmonic content, corresponding to a proportion of non-linear load under 20% of the upstream transformer rated power supplied for almost all system voltages occurring throughout the world
• Ratings from 75 to 500 kvar per unit, where required also with upstream AF blocking device
  

Principles:

• The power factor controller measures the inductive reactive power present in the network and also the corresponding power factor. It compares this with the set target cos phi and switches capacitors in or out as required using the contactors in the capacitor modules
• The number of switchings is optimized

 
Characteristics:

• Saving energy costs, relieving transformers and connecting cables, reducing transmission losses by the application of 4RY power factor correction units
• Controlled centralized compensation, ready for connection for main and subdistribution in power systems with non-linear loads under 20% of the upstream transformer rated power
• Type-tested switchgear assembly (TSK) according to EN 60439-1, IEC 439-1 for indoor insatallation
• Comprehensive range of types, various housing variants, natural cabinet cooling, degrees of protection up to IP54
