About EPA
EPA GmbH, headquartered in Bruchköbel, specializes in drive, EMC and leakage current technology. The product portfolio includes frequency inverters and servo technology (including Unidrive M700, @DRIVE compact), input and output filters such as mains filters, harmonic filters, sine filters and motor chokes, as well as low-leakage EMC filters and leakage current compensation devices developed in-house, including the LEAKCOMP®, LEAKWATCH, DiffDi®, PECON+® systems and the reduction filters NF-DAR/KC-DAR. In addition, the company offers the complete drive solution from planning through implementation to the finished drive unit. Services include EMC measurements in the company's own laboratory or on site, EMC and leakage current consulting, on-demand production support including customer-specific labeling, a rental service for leakage current products, and an emergency service with express delivery. With more than 35 years of industry experience, EPA serves customers in nearly all industrial sectors, particularly manufacturing and processing automation. For customer-specific goods, the company maintains a safety stock with regular review; upon request, devices and packaging are provided with individual logistics labels.

Products & Technologies
Mains filters (single-/three-phase, with neutral conductor, sub-panel mount,
Input filters for reducing EMC interference, available as standard and sub-panel versions with low-leakage PreLEAK® technology.
Harmonic filters
Filters for reducing harmonic currents at the input of drive solutions.
Sine filters, motor chokes, absorption filters
Output filters for improving motor operation and suppressing undesirable leakage currents.
Leakage current reduction filters NF-DAR/KC-DAR
Suppresses undesirable leakage currents from 2 kHz for rated currents from 10 A to 180 A and increases operational safety in systems with RCDs.
Leakage current compensation LEAKCOMP® (HP, HP eco, 1P, 1C)
Compensates operational leakage currents (LEAKCOMP® HP eco up to 300 mA RMS) and enables the use of RCDs from 30 mA in accordance with DIN VDE 0100-530.
Leakage current analysis LEAKWATCH / DiffDi®
Measurement and analysis system incl. measurement clamp LW-MZ-50 for direct leakage current measurement without interrupting the current path.
Unidrive M700 (AC and servo inverters)
Inverter series for automation applications in the processing industry, compatible upgrade for Unidrive SP.
@DRIVE® compact
Smallest version of the decentralized drive system, mountable directly on the motor or on the wall.

Additional services
Quality
EPA tests devices and systems for electromagnetic interference with modern EMC measuring equipment in its own laboratory or on site at the customer. Leakage current measurements are performed, among other things, with the LEAKWATCH measurement and analysis system, which works without interrupting the current path.
