ABB S-073N 3BHB009884R0021
The ABB S-073N 3BHB009884R0021 module is a phase module produced by ABB for AC inverter systems. It is typically integrated into ABB’s ACS6000 series drives and is used to detect and deal with phase sequence, phase loss and phase imbalance of three-phase power supplies.
Product name and description
Product name: ABB S-073N phase module
Description: The module is mainly used to detect the phase sequence, lack of phase and phase imbalance of the three-phase power supply, and feedback the detection results to the inverter to ensure the safe operation of the inverter.
Main function
Phase sequence detection: Detect the phase sequence of the three-phase power supply to ensure that the inverter is connected to the correct phase sequence.
Phase loss detection: Detect whether the three-phase power supply is phase loss to prevent the inverter from starting in the case of phase loss.
Phase unbalance detection: Detect whether the phase voltage of the three-phase power supply is balanced to prevent the phase unbalance from causing damage to the inverter.
