Description

• Model: SLOV4.6/5.3
• Part Number: 3BHL000734P0003
• Brand: TRAFO / ABB-associated power electronics spare
• Part Type: Transformer interface and monitoring board
• Application: ABB power-electronics and converter systems
• Reported Supply: 24 VDC nominal; verify against the installed system documentation

Technical Introduction

The TRAFO SLOV4.6/5.3 3BHL000734P0003 is identified in industrial spare-part references as a transformer interface and monitoring board associated with ABB power-electronics equipment. Available listings describe the unit as an electronic module used to interface transformer-related measurements and protection signals with a control system.

The part number 3BHL000734P0003 is repeatedly listed together with SLOV4.6/5.3 in ABB-related spare inventories, supporting the identification of the complete designation pair. Because detailed OEM documentation for this exact assembly is limited in publicly indexed sources, electrical interfaces, exact cabinet position, and system compatibility should be confirmed against the installed equipment before procurement.

Engineer’s Takeaway: For legacy ABB power-conversion equipment, source the board by the complete SLOV4.6/5.3 / 3BHL000734P0003 identification and verify the target system before approving a substitution.

Core Technical Specifications

The dimensional, weight, supply, origin, status, and warranty data above come from a third-party industrial spare listing and should be independently verified against the physical unit and applicable OEM documentation before use for engineering, shipping, or compliance purposes.

Field Engineer’s Tech Notes

1. Verify the exact system before installation.
Do not assume that every SLOV4.6/5.3 board is interchangeable across power-conversion systems. Check the equipment type, rack or cabinet location, connector configuration, and installed revision before replacing the unit.

2. Preserve transformer measurement scaling.
Where the board participates in transformer voltage, current, or protection signal processing, the scaling and signal configuration must match the installed transformer instrumentation. A physically correct board with incorrect system scaling can produce misleading protection or monitoring values.

Adaptive QA & Testing Protocol

Incoming QA begins with inspection of the .6/5.3 / 3BHL000734P0003 identification, board revision, connector condition, PCB coating, mounting hardware, and signs of corrosion, contamination, or thermal damage.

Functional verification should be performed in the appropriate ABB power-electronics test environment. Where the system permits, checks can include board power-up, status indications, signal-path verification, control-system recognition, and the applicable transformer monitoring inputs. Any configured measurement scaling should be compared with the existing installation records before commissioning.

Inspection photographs, test reports, and available test videos can be provided upon request.

Buyer’s FAQ

What is 3BHL000734P0003 .6/5.3?

Available industrial references identify it as a transformer interface and monitoring board used in ABB-associated power-electronics applications.

Is this a direct replacement for another SLOV board?

Not automatically. Confirm the full part number, hardware revision, host equipment, connector configuration, and application before approving a direct replacement.

Is the unit new or refurbished?

Condition must be confirmed against the actual inventory. The referenced supplier listing describes its offered unit as 100% new, but buyers should request confirmation for the specific stock item being quoted.

What are the lead time and warranty?

The referenced listing reports the unit as in stock with a one-year warranty, but commercial availability can change. Request written confirmation of current stock, condition, test status, warranty, and dispatch lead time before issuing the purchase order.
