SOMANET Braking Chopper 48V 500W consumes excessive energy while a motor decelerates a load (also referred to as shunt or regen board).
When the motor is used for actively decelerating a load, electrical power will be regenerated. If the drives are supplied by a standard power supply (with no recuperation function), such regenerative operating points will cause overvoltage on the DC circuit, thus either the drive or the power supply will shut down.
To prevent this from happening, a shunt circuit is needed to burn this recuperated energy.
dissipates 430 W peak power
dissipates up to 90 W continuous power if adequate cooling is provided
