Features of a regenerative power supply unit compared to an inverter with braking resistors

• Energy balance: Regenerative power is fed back into the supply system instead of being converted into waste heat.
• Reduced complexity of installation when there are several inverters (mains and braking resistor connections). However, a braking resistor is required for bringing the drive to a controlled stop even when there is a disruption in the supply system.
• Reduction in use of control cabinet space and fan power if the braking resistor was previously installed in the control cabinet.
