Hyundai HIVD910 PB-NHM91-400 Power Supply Board

The Hyundai HIVD910 PB-NHM91-400 Power Supply Board is an internal power PCB used in the HIVD910 elevator inverter system. It supplies the low-voltage power required by the inverter control electronics and is mainly used for repair or replacement of an existing PB-NHM91-400 board.

A Power Board, Not the Main Control PCB

The PB-NHM91-400 belongs to the power supply section of the HIVD910 inverter.

It should be distinguished from the HIVD910 Main Board, which handles the main drive control functions. When an inverter is being repaired, identifying which PCB has failed is important before ordering replacement parts.

The PB-NHM91-400 marking is the primary reference for this board.

For replacement checking, please provide:

• Board model: PB-NHM91-400

• Inverter model: HIVD910

• Front and rear PCB photos

• Connector and terminal arrangement

• Additional labels or revision markings

• Required quantity

Use the Original PCB as the Reference

If the inverter has been repaired previously, do not rely only on the HIVD910 inverter name. Compare the board number and physical configuration with the installed PCB.
