Allen-Bradley 2198-P031 Kinetix 5700 DC Power Supply

The 2198-P031 is a Kinetix 5700 series DC-bus power supply manufactured by Allen-Bradley for multi-axis industrial motion control architectures. It converts three-phase AC input voltage into a regulated DC bus voltage, providing reliable continuous power and current to downstream servo drive inverters in high-performance automation systems.

Technical Specifications

Power Conversion and System Integration

Designed for demanding machine configurations, the unit accepts a 3-phase 324–528 VAC input and delivers 7 kW of continuous output power with a 10.5 A current rating. It utilizes a shared-bus connection system to distribute DC power and 24V control power efficiently across multiple drive modules without requiring complex external wiring.

Protection and Safety Features

The built-in contactor-enable circuitry features an integrated relay that protects the entire Kinetix 5700 drive assembly during overloads or unexpected fault conditions. By wiring the AC three-phase contactor control string in series with this contactor-enable interface, the system ensures rapid shutdown capabilities to prevent electrical or mechanical damage.

Frequently Asked Questions

Q: What is the primary function of the Allen-Bradley 2198-P031 module within a motion control setup? A: It functions as a DC-bus converter power supply that converts standard 3-phase AC line voltage into the shared DC bus power required to drive Kinetix 5700 servo inverter modules.

Q: Can this power supply be used in ungrounded AC distribution systems? A: Yes, but for ungrounded or impedance-grounded AC systems, you must remove the factory-installed ground screw according to the system installation instructions.
