INDRAMAT HVE04.2-W075N Power supply DIAX04

Buy online your INDRAMAT HVE04.2-W075N Power supply DIAX04 reference HVE04.2-W075N from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This INDRAMAT module from the HVE family supplies the DC bus for DIAX04 servo systems used on industrial machine-tools. It converts a 3-phase 380-480 VAC mains input into an unregulated DC bus that feeds DIAX04 drive controllers across multiple axes. Commonly sourced as a replacement unit or spare part for legacy Indramat cabinets, it is suitable for field replacement on mills, lathes, grinders and transfer machinery running DIAX04. Ordering references frequently seen in the field include HVEO4.2-WO75N and HVE04-2-W075N.

Within a DIAX04 rack this HVE module acts as the front-end supply that stabilizes machine operation by delivering the required DC link to the servo controllers. When a supply fails, axes typically drop out or alarms appear on the drive chain. Installing a known good HVE04.2-W075N restores the bus and returns the drive system to service once downstream faults are cleared.

Designed for plants running 480 VAC mains as well as installations wired for 380-400 VAC, this unit supports demanding applications where multiple axes accelerate and decelerate under heavy load. A nominal capability up to 75 kW with current handling around 120 A suits large DIAX04 cabinets found on high-duty machine-tools. Front-mounted power and control terminals simplify access during a drop-in replacement and help reduce machine downtime for maintenance teams.

The HVE04.2-W075N belongs to the INDRAMAT DIAX04 ecosystem. When swapped like-for-like it fits the original space claim, interfaces with existing bus bars and terminal layouts, and works with the machine’s matched braking and discharge components as defined by the OEM. This makes it a practical choice for retrofits and repairs where cabinet modifications are not desired.

Reference: HVE04.2-W075N

Manufacturer: INDRAMAT

Product type: INDRAMAT Power Supply

Main function: Provides the unregulated DC link feeding DIAX04 servo drive modules in Indramat cabinets

Applications: Machine-tools and industrial equipment built on DIAX04, including lathes, machining centers, grinders and transfer lines, as well as retrofit and field replacement projects

Key technical data: Three-phase input 380-480 VAC, current capability around 120 A, up to 75 kW DC bus delivery, unregulated DC bus architecture per HVE design, front-mounted terminals for straightforward cabinet access, built for the DIAX04 system and manufactured in Germany. Known ordering variants include HVEO4.2-WO75N and HVE04-2-W075N.

On the production floor this unit is typically replaced during unplanned stops when the DIAX04 rack loses DC bus or when a preventive change-out is scheduled on high-hour systems. Keeping a tested unit in spare inventory shortens repair turnaround and helps maintenance teams bring machines back online quickly. For plants running older Indramat cabinets, a like-for-like HVE04.2-W075N is a practical way to extend machine uptime without reengineering the drive section.

Each module is examined on appropriate CNC test benches or simulators by skilled engineers and supplied with a functional warranty. Packaging is prepared for industrial shipping so the unit arrives ready for field replacement. Many stocked items ship directly from our Florida facility.

For legacy and obsolete Indramat systems, this part is often used as an emergency spare to reduce unexpected downtime. Cnc-shopping USA can assist with sourcing, repair service or exchange service options when available, helping older DIAX04 installations remain operational.

Frequently asked questions about HVE04.2-W075N:

Is this module suitable for 480 VAC plants in North America?
Yes, it accepts a three-phase 380-480 VAC input. Confirm the cabinet wiring and the rating plate to match your installation before replacement.

Does the HVE supply deliver a regulated DC output?
No, the HVE family provides an unregulated DC bus as designed by Indramat. The DIAX04 drive modules operate correctly with this bus topology.

Can I use this as a drop-in replacement for the same HVE04.2 variant?
When matched to the original rating and variant code, it installs as a drop-in within the DIAX04 cabinet using the front-mounted terminals and the existing bus connections.

How should I select the correct rating for a retrofit?
Match the original machine specification and power rating. Use the 75 kW class and current capability as guidance, and align with the cabinet’s drive load and OEM documentation.
