FLLD3 … PV
High current 3-phase EMC Filter
Overview
The three phase filter series is intended to be used in energy
conversion inverter systems (e.g. photo voltaic and wind power),
between the inverter and the line or in motor drive systems.
The filters are optimized for geometry and power loss.

The FLLD3…PV series is designed according to IEC/EN 60939 and UL 1283.
*) Maximum leakage current under normal operating conditions.
If two phases are interrupted, leakage current can be much higher.
Filters without Y-capacitors have no leakage current.
