OUTPUT CHOKES
Chokes are fitted to the output of the inverter to
allow operation with long cables. The choke
compensates for the stray capacitance of the
cables. Recommended chokes for different cable
lengths and inverters are available.
Output Choke Order Numbers
The maximum switching frequency must
be limited to 2kHz for iron cored chokes
and 4kHz for ferrite cored chokes.
