250 Watt 82 ohm regenerative resistor suitable for Argon drive
Regenerative resistors are usually a part with servo systems to absorb returned energy from decelerating or braking servo axis.

Servo drive with motor can act two ways: energy supply and energy generator. The generator behavior occurs during decelerations and this causes current flow from motor to drive power supply capacitors. If that generated energy is not absorbed anywhere, the voltage of capacitors will rise above overvoltage threshold and trigger an software clearable overvoltage fault.
