Products Description
ABB ZINT-592 3AUA0000103603 Power Board
The ABB ZINT-592 3AUA0000103603 Power Board is a dedicated internal power interface board used in specific ABB industrial drive assemblies. It is designed to handle localized power distribution and power-related signal coordination for internal drive modules. Rather than supplying external loads, this board supports the stable operation of control and interface boards that rely on regulated internal power paths.
Within the ZINT-592 family, this version is identified by ABB part number 3AUA0000103603 and is supplied as an original spare board for exact replacement in compatible drive systems.
With over 50 million in inventory, PLC EXPORT delivers only brand-new, authentic components- ready to ship,
rigorously tested, and backed by professional technical support.

Functional Role / System Position
The ZINT-592 Power Board is installed inside the drive cabinet and operates as part of the internal power layer. Its position can be described as:
Incoming Drive Power → Internal Power Conditioning Section → ZINT-592 Power Board → Control Board / Interface Modules → Gate Control and Power Stage
In this position, the board ensures that internal electronic modules receive stable and coordinated power, supporting correct timing and behavior of downstream control functions.
Key Features / Functional Capabilities
◆ Internal power interface board dedicated to ZINT-592 drive architecture
◆ Supports power distribution to control and interface modules within the drive
◆ Designed to operate in close proximity to high-current power sections
◆ PCB layout optimized for electrical separation and internal noise suppression
◆ Supports stable internal operation during load changes and speed regulation
◆ Supplied as a direct-fit replacement with no functional modification required
Application Areas / Typical Use Cases
This power board is used inside ABB industrial variable frequency drives installed in motor control systems for production machinery. Typical use cases include drives controlling pumps, compressors, fans, conveyors, and other rotating equipment where stable internal power distribution is critical for control accuracy and long-term reliability.
It is most commonly replaced during corrective maintenance, refurbishment, or life-extension projects of existing ABB drive installations.

Installation / Handling
The ZINT-592 Power Board must be installed in the designated internal slot or mounting position defined by the drive design. All power must be disconnected before installation. Proper connector seating and mechanical fixation are essential to maintain internal power integrity. ESD protection is mandatory during handling.
Advantages / Value Highlights
Using the correct ZINT-592 3AUA0000103603 Power Board ensures that internal control modules receive stable and correctly routed power. This helps prevent abnormal drive behavior caused by internal voltage instability and supports predictable operation after board replacement. Exact-model replacement also avoids compatibility risks associated with similar but non-matching ZINT boards.
Supply & Warranty Information
One-year warranty. The board is supplied through authorized ABB and industrial automation spare parts distribution channels.

Common problems
Q1: What distinguishes the ZINT-592 Power Board from external power supplies?
It does not supply field devices or motors; it manages internal power distribution for drive electronics only.
Q2: Is this board interchangeable with other ZINT-series boards?
No, it must match the exact ZINT-592 version specified for the drive model.
Q3: Which internal modules depend on this board?
Control boards and interface modules inside the drive rely on this board for stable power routing.
Q4: Is software configuration required after replacement?
No configuration is required when replacing the board with the same part number.
Q5: When is this board typically replaced?
It is usually replaced during fault repair, preventive maintenance, or drive refurbishment.
