SCHNEIDER ELECTRIC VZ27 - Braking Resistor
This component is a dedicated braking resistor designed for integration with SCHNEIDER ELECTRIC Altivar variable speed drives. Its primary function is to dissipate regenerative energy generated by decelerating motors, preventing overvoltage conditions on the DC bus and enabling controlled, rapid stopping of industrial machinery. It is critical for applications requiring frequent braking, high inertia load handling, or precise motion control in systems such as conveyors, centrifuges, and lifting equipment.
