Electric filter for high-power grid-connected electric machinery

Danfoss Power Solutions announces the launch of the Editron EC-LCL1200B-350, a heavy-duty LCL electric filter specifically designed for off-highway applications.

The LCL1200B electric filter is a compact yet robust mobile-grade solution for fully electric, high-power machinery that pulls power from the AC grid rather than batteries. Applications include drilling equipment, material handling equipment, grid-connected excavators, and other tethered electric machinery.

The LCL1200B filter is designed to be used with the EC-C1200-450-L electric converter. Together the two components create a grid connection, ensuring compliance with standards. The EC-C1200 converts AC power from the grid to provide DC power for the machine, while the LCL1200B filter reduces electromagnetic interference, improving power quality and maintaining system reliability. The combination of components is bidirectional, meaning that it can take power from the grid and feed power back to the grid. 

The LCL1200B electric filter is a mobile-grade solution for machinery operating in demanding off-highway environments. The filter’s robust design withstands high levels of mechanical vibration and shock, while its ingress protection ratings of IP6K9K and IP67 protect from moisture and dust. 

Alternative electric filters are primarily industrial solutions designed for stationary applications, requiring additional measures to provide the same level of protection in harsh conditions. The filter’s compact design also makes it a better fit for mobile machinery, saving space and reducing weight. 

Rated for up to 560 volts AC and 50/60 Hz, the LCL1200B filter is compatible with European and U.S. three-phase power supplies. All components are rated for 300 A_RMS and 250 kVA. The filter is designed for operating altitudes of up to 4,000 metres.
