175 Ohm 1 kW Braking Resistor

DERELL Braking Resistors are high-quality energy dissipation resistors developed for use with variable frequency drives (AC Motor Drives / VFD). They safely convert the regenerative energy generated during motor deceleration and stopping into heat, helping to protect your drive and ensuring the safe operation of your system.

The special aluminum alloy used in its housing provides high heat dissipation, helping the resistor element to cool down more efficiently. Thanks to its finned extruded aluminum enclosure, effective cooling is achieved through natural air convection, while its robust mechanical construction ensures long-term reliable use.

++ Why should I use a braking resistor with my VFD?
