TDK Announces High-Performance EPCOS PFC Thyristor Module
TDK Corporation (Iselin, NJ) has extended its BR7000 series of EPCOS power factor controllers with two new types. The BR7000-I-TH controller offers 12 relay outputs for capacitor contactors and 12 transistor outputs for thyristor modules.
The new controllers are particularly well matched to the thyristor modules of the new TSM-LC-S series for dynamic power factor correction with a rating of up to 55 kvar. They detect and store key grid and capacitor parameters. This enables the implementation of complex PFC installations, which are also self-monitoring, thereby improving system protection and helping to increase the operating life of the capacitors.
Both controllers already offer 20 pre-installed control series. In addition to the most important grid parameters such as voltage, current, frequency as well as reactive, apparent and effective power, they also measure the distortion of current and voltage (THD-I/THD-V). The graphics display the results up to the 33rd harmonic. These controllers are designed for voltages of between 30 and 440 V AC (L-N), or of 50 to 760 V AC (L-L).
Main features include:
- Control of up to 32 EPCOS TSM-LC-S thyristor modules by an RS485 interface.
- Bidirectional communication with the thyristor modules.
- Display of a wide range of parameters including the harmonics.
