Lenze i750 - Brake Resistors; Mains Chokes

Brake resistors
•
T
o decelerate greater moments of inera or with a longer operaon in generator mode an
external brake resistor is required.
•
The brake resistor absorbs the produced brake energy and converts it into heat.

Mains chokes
•
Mains chok
es reduce the feedback eects of the inverter on the supplying mains by their
high inducve resistance reducing high-frequency interference.
•
The eecve mains current is reduced which saves energy.
•
Mains chokes can be used without restricons in conjuncon with RFI lters.
•
Please note that the use of a mains choke reduces the mains voltage at the input of the
inverter by4 % (typical voltage drop across the mains choke in the rated point).
