Kollmorgen B-204-C-31-B3
Overview: The B-204-C-31-B3 is a regenerative braking unit (brake chopper) from the Kollmorgen B-200 product series. Unlike a passive braking resistor (B-600 series), the B-204 is an active electronic module that switches the DC bus energy to an external braking resistor with precise duty-cycle control. The model code: B-204 (B-200 series, 4 kW class) + C (configuration variant) + 31 (specific electrical rating) + B3 (terminal/connector variant). This unit is used in applications with high regeneration duty cycles where precise DC bus voltage clamping is required.
