dynamic brake
(OP)
Hi again!
Is the dynamic brake circuit (standard switch with in series a resistor limiting the maximum current) widely employed only in application where is demanded high current sinked???
I saw a schematic, for ac motor, where the switch for the dynamic brake had to carry 2A.

for more info. Dynamic brake circuit current ratings depend on the motor HP rating and motor voltage rating.
