Product Description

Allen-Bradley 2198-P031 — Kinetix 5700 DC Bus Power Supply

Catalog #: 2198-P031 | Manufacturer: Rockwell Automation / Allen-Bradley | Series: Kinetix 5700

Built for the demands of high-axis-count servo systems, the Allen-Bradley 2198-P031 is the entry-level DC bus power supply in the Kinetix 5700 drive family. This is a genuine Rockwell Automation unit — not a clone, not a grey-market substitute — stocked and ready to ship.

Overview

The 2198-P031 sits at the heart of Kinetix 5700 multi-axis servo installations. Its job is straightforward but critical: convert three-phase AC mains power into a clean, regulated DC bus that feeds single-axis and dual-axis inverter modules across the drive cluster.

What makes this supply stand out is the combination of high efficiency, compact footprint, and tool-free assembly — features that reduce both panel space and commissioning hours on large machine builds.

Performance & Design Highlights

Snap-fit, tool-free installation. The 2198-P031 uses a mechanical snap-fit mounting system — no tools required to seat or remove the module from the drive cluster. This cuts installation time significantly, especially in multi-axis cabinets where space is tight.

Integrated LC filter. Rather than requiring an external line filter, the 2198-P031 incorporates an LC filter directly into the module. That eliminates a separate component, saves panel real estate, and reduces overall system wiring complexity.

Scalable bus power. A single Kinetix 5700 drive system can support up to three 2198-P031 units operating in parallel. This means you can start with one supply and add capacity incrementally as machine requirements grow — without changing the base hardware.

99% efficiency. At 99% measured efficiency, heat generation is minimal, which translates to lower cooling demands inside the enclosure and longer component service life.

Industry-proven application range. The Kinetix 5700 platform — with the 2198-P031 as its power foundation — is deployed across beverage filling lines, diaper machine production, bag-making equipment, tire building machinery, and high-speed tray loaders, among others.

Mounting & Installation Notes

The 2198-P031 must be installed in an upright vertical orientation — horizontal or inverted mounting is not supported. Operating environment should be kept within 0–50°C. Wiring requires copper conductors rated for a minimum of 75°C, with a 10 mm strip length and terminal torque between 0.5–0.8 N·m (4.4–7.1 lb·in). A contactor-enable relay wiring connection is required as part of the safety circuit before commissioning.

Ground-shielded power cables are recommended to protect the system from high-frequency transients on the shield conductor.

FAQ

Q: What drive system is the 2198-P031 designed for? It is designed exclusively for the Allen-Bradley Kinetix 5700 servo drive platform. It supplies DC bus power to the single-axis (2198-Sxxx) and dual-axis (2198-Dxxx) inverter modules within a Kinetix 5700 cluster.

Q: How many 2198-P031 units can be used in a single drive system? Up to three 2198-P031 units can be installed in parallel within a single Kinetix 5700 system, allowing cumulative bus power to scale beyond the 7 kW rating of a single module.

Q: What is the AC input voltage range? The module accepts three-phase AC input from 324 to 528 VAC, covering both 230V-class and 480V-class installations. The nominal design voltages are 230V and 480V.

Q: Does this unit include an integrated line filter? Yes. The 2198-P031 has a built-in LC filter, which eliminates the need for a separate external EMC line filter in most standard installations.

Q: What certifications does the 2198-P031 carry? The unit is certified to UL, cUL, C-TICK (Australia/New Zealand), and KC (South Korea) standards, making it suitable for deployment across North American, Asia-Pacific, and select international markets.

Q: Can this supply be mounted horizontally? No. Rockwell Automation specifies upright vertical mounting only. Horizontal or inverted installation is not permitted and may void compliance with the module's thermal and safety ratings.

Q: What is the peak output current? While the continuous output current is 10.5 A DC, the module can deliver up to 31.6 A DC peak — providing headroom to handle servo transient demands during acceleration and deceleration cycles.

Q: Is this a genuine Allen-Bradley part? Yes. This is an authentic Rockwell Automation / Allen-Bradley catalog item (2198-P031), not an aftermarket reproduction.

Q: What wire type and torque is required for installation? Copper conductors with a minimum 75°C temperature rating are required. Terminal strip length should be 10 mm, and terminals should be torqued to 0.5–0.8 N·m (4.4–7.1 lb·in).

Q: What industries commonly use this power supply? The Kinetix 5700 system — powered by the 2198-P031 — is widely used in packaging machinery, beverage production lines, diaper manufacturing, tire building equipment, bag-making machines, and other high-axis-count industrial automation applications.
