Single-phase line reactors ED1N
The ED1N line reactors are used in single-phase supply systems, usually for protecting power thyristors and transistors against rapid growth of current. Moreover, the line chokes limit commutation over-voltages in the circuit and backward current impulse amplitude when switching off thyristors. The line chokes also function as protectors of the supply network against higher harmonic propagation.
The range of possible versions is limited by the following equation:
0,05 < 2π f x L x I2 x 10-6 < 100
where: f - [Hz], L - [mH], I - [A]
