ABB DSMB-01C ACS800 Power Supply Board

Description

Key Technical Specifications

The ABB product record does not publish a generic input/output voltage rating or wattage for DSMB-01C. Those values should not be inferred from third-party descriptions. The available ABB data instead identifies the board as a power-supply PCB, gives its physical construction and dimensions, and associates it with the ACS800DSUV3 kit.

Product Introduction

The ABB DSMB-01C, product ID 64691929, is a power supply board used within ABB drive equipment and specifically documented as part of the ACS800DSUV3 kit. ABB classifies it as a power supply board rather than a communication or fiber-optic interface module. The documented PCB construction is 4-layer with technical dimensions of 384 × 89.5 mm.

This distinction matters because several secondary-market listings incorrectly describe DSMB-01C as a communication module, star coupler, or detection board. Those descriptions conflict with ABB’s product identification for 64691929. For procurement and replacement, match the complete ABB designation and product ID against the installed board and drive documentation.

Installation & Configuration Guide

Stage 1 — Pre-Installation Preparation

1. Verify the PCB marking is DSMB-01C and the ABB product ID is 64691929.
2. Confirm that the board is being installed in the correct ABB drive assembly, particularly where the application documentation identifies an ACS800DSUV3 kit.
3. Record all board connectors, wiring positions, jumpers, LEDs, and visible configuration details before removal.
4. Back up the associated drive parameters and application configuration.
5. Apply the site’s lockout/tagout procedure and isolate all incoming power sources.
6. Wait for the drive’s DC-link voltage to fall to the level specified by the applicable ABB ACS800 service documentation, then verify absence of hazardous voltage with an appropriately rated meter.
7. Use ESD protection when handling the PCB.

Stage 2 — Removing the Old Module

1. Confirm the drive is fully isolated and the DC bus has been verified safe.
2. Photograph the installed DSMB-01C and all connected wiring.
3. Label connectors before disconnecting them.
4. Release the PCB mounting hardware and remove the board without flexing it.
5. Inspect the connector contacts, mounting points, adjacent boards, and wiring for heat damage or contamination.
6. Check the removed board for burned components, swollen capacitors, cracked solder joints, or other evidence of an upstream fault.
7. Do not install a replacement board until the cause of the original power-supply failure has been investigated.

Stage 3 — Installing the New Module

1. Compare the replacement against and the removed PCB.
2. Confirm the physical dimensions, connector locations, mounting points, and board revision.
3. Install the PCB without forcing connectors or mounting hardware.
4. Reconnect every cable according to the recorded positions and the applicable ABB wiring documentation.
5. Inspect cable routing to ensure that conductors cannot contact heatsinks or other high-temperature components.
6. Confirm protective grounding and any required shield connections.
7. Recheck all connectors before closing the drive cabinet.
8. Do not substitute another DSMB-family board solely because its PCB dimensions appear similar.

Stage 4 — Power-On & Testing

1. Complete a final visual inspection before restoring power.
2. Verify that all covers, barriers, grounding conductors, and safety interlocks are correctly installed.
3. Energize the drive under the site’s approved commissioning procedure.
4. Check the drive for power-supply, DC-bus, control-board, or communication-related fault indications.
5. Verify the expected internal control voltages according to the applicable ABB service documentation rather than using unverified generic voltage values.
6. Restore the backed-up drive parameters if required.
7. Test the drive first without production load, then perform a controlled low-speed/load test.
8. Monitor alarms, temperature, abnormal noise, and repeated fault codes during the test.
9. If the replacement board fails immediately, remove power and investigate the downstream circuit before fitting another PCB.

Frequently Asked Questions (FAQ)

Q1: What is the ABB ?
The is an ABB power supply board, product ID 64691929. ABB’s product record specifically classifies it as a power supply board and lists its use in the ACS800DSUV3 kit.

Q2: What is the ABB part number for ?
The primary ABB product ID is 64691929. The related ordering/reference number 3AFE64691929 also appears in secondary-market documentation.

Q3: Is a communication or fiber-optic module?
No. ABB’s product data identifies as a POWER SUPPLY BOARD. Some third-party listings use the same model designation for unrelated descriptions such as DDCS star couplers; those descriptions should not be accepted without matching the physical board and ABB part number.

Q4: Which ABB equipment is associated with ?
ABB’s available product record lists ACS800DSUV3 as a kit in which is used. Secondary-market listings also associate the board with ABB ACS800 MultiDrive equipment, but the exact cabinet and assembly should be verified from the machine documentation.

Q5: What are the physical specifications of ?
ABB’s technical information specifies a 384 × 89.5 mm, 4-layer PCB with a 0.95 kg net weight.

Q6: Is available as a new replacement?
ABB’s product record identifies the part type as New and lists multiple ABB stock locations. Current secondary-market listings also advertise new units, although actual stock, packaging, revision, and warranty depend on the individual supplier.

Q7: What should be verified before purchasing ?
Verify , ABB product ID 64691929, the complete PCB revision/markings, physical connector arrangement, and the exact ACS800 cabinet or kit in which the board is installed. This is particularly important because online listings currently contain conflicting descriptions of the same model number.
