Why Choose the Lovato VLBXR390 Braking Resistor?
The Lovato VLBXR390 is a dedicated braking resistor for Lovato VLB3 variable speed drives, designed to support controlled motor deceleration in compact industrial drive applications. It dissipates regenerative energy generated during braking, helping the drive manage stopping cycles safely and reliably.
This braking resistor is suitable for smaller motor control systems where motors need to stop quickly, slow down frequently or operate in applications with repeated deceleration. By providing an external route for braking energy, the VLBXR390 helps reduce overvoltage trips, improve stopping performance and support dependable machine operation.
With a 390 Ω resistance value, 100 W power rating and compatibility with Lovato VLB3 drives from 0.4 to 0.75 kW, the VLBXR390 is a practical accessory for compact industrial control panels, OEM machinery and automation systems using Lovato variable speed drives.
