Active Filter
Our FRANKE Elektrotechnik active filters “Made in GERMANY” have been in use worldwide for many years and meet the highest standards of speed, reliability, durability and are designed for a wide range of applications and problem solutions in power grids.
For exceptionally dirty and hot ambient conditions, active filters with water cooling IP 65 are available.
The number of faults in industrial plants is constantly increasing.
Problems and failures in control systems and devices are becoming more and more common.
Active Filters can help with a wide range of power grid problems.
We support our customers worldwide from conception with network analysis to commissioning.
FE-AF series of Active Filters
- Harmonic compensation up to the 49th harmonic (selectable individually)
- Selective detection of grid resonance
- Flicker compensation
- Ultra-fast reactive power compensation (inductive and capacitive)
- Load balancing between phases and neutral conductor relief
- Effective power grid resonance detection with blocking of resonance currents
- Highest performance, response time <21μs
- Less power loss due to 3 NPC topology
- Very low losses (less than 15 watts per ampere)
- Available as 3-wire and 4-wire version
- Modular system expandable from 60A to 300A per system
- Advanced control algorithms with SDC (selective direct control)
- Ethernet connection and internal and Ether CAT interconnection system
- Superior user interface with installation wizard
- Power analyzer function
- Air-cooled systems
- Water-cooled systems for harsh environmental conditions (IP65)
- User-friendly operation
- High reliability
- Robust against changes in network parameters
- It consists of a modular structure, each in IN = 60 A steps
Control unit (HMI)
Our touch display offers the following options:
- Setting and commissioning
- Display of the current values of current and voltage
- Event log (error / event memory)
- Switching the active filter on / off
- Connection via Ethernet (web server) or Modbus
