Brake Resistor · 100 ohm 500 W VFD braking accessory · Delta Electronics BR500W100
SKU: DE-BR500W100
500 W, 100 ohm braking resistor for Delta variable frequency drive braking applications. Commonly used to dissipate regenerative energy during deceleration; compatibility depends on the drive series, voltage class, braking unit, and programmed deceleration settings.
What this product is for
This brake resistor is used with compatible Delta variable frequency drive (VFD) systems to absorb regenerative energy during motor deceleration. It helps reduce overvoltage trips when stopping higher-inertia loads more quickly.
Use for
Use for VFD braking circuits where the drive manual or braking resistor chart calls for a 100 ohm, 500 W resistor. Typical applications include conveyors, spindles, fans, and other motor loads that need controlled stopping.
Avoid for
Avoid using this resistor as a general-purpose panel resistor or as a substitute where a different ohm value or wattage is specified. Do not select by physical fit alone; braking resistor value must match the drive requirements.
Best for
Best for Delta drive installations where the specified braking resistor is BR500W100 or where the manufacturer chart calls for 100 ohm at 500 W. It is suited to applications needing faster deceleration than coast-to-stop, subject to the drive and machine limits.
Installed in
Typically installed in industrial control panels, machine cabinets, and automation systems with adequate clearance and ventilation. Because braking resistors convert excess energy into heat, mounting location and enclosure heat management matter.
Why this product exists
When a motor is decelerated by a VFD, regenerated energy can raise DC bus voltage. A braking resistor provides a controlled path to dissipate that energy as heat, helping the system stop faster and reducing nuisance faults.
Compared with similar products
This model is a defined 100 ohm, 500 W Delta braking resistor, not a generic fixed resistor for electronics repair. Compared with lower-wattage units, it is intended for higher braking energy. Compared with other brake resistors, the key selection points are resistance, wattage, drive voltage class, and whether an external brake unit is required. As typical guidance only, more aggressive deceleration usually increases braking demand. Actual performance depends on load inertia, duty cycle, installation conditions, and local electrical code.
