ALLEN BRADLEY 1495-N73 - Dynamic Braking Resistor
The ALLEN BRADLEY 1495-N73 is a dynamic braking resistor from the 1495 series, engineered to dissipate regenerative energy generated by decelerating AC motors controlled by variable frequency drives. This passive component prevents overvoltage conditions on the DC bus of VFDs, enabling controlled deceleration and frequent stopping cycles. It is critical for applications involving high-inertia loads, rapid deceleration requirements, and vertical axis control in material handling, cranes, and machine tools.
