ABB SR511, order 3BSE000863R1, is the 24V/5V voltage regulator used in Advant controller power systems. ABB classifies it as a power-supply product and identifies a 310 W DC/DC version in its AC450 parts literature. The official product records associate SR511 with AC450 and AC460 system units.
The regulator has a net depth of 117 mm, height of 243 mm and width of 54 mm, with a net weight of 1.6 kg. ABB AC450 documentation permits up to two SR511 regulators in a dual-redundant arrangement. The complete supply configuration, cabinet wiring and installed hardware revision must be matched before selecting a replacement.
For maintenance and MRO procurement, specify the complete regulator order number and document the connected power system. Capture nameplate photographs, connector condition and the redundancy arrangement before removal. After an approved replacement, verify the controller supply under its intended load and retain the acceptance results with the cabinet service record.

Preserve the installed power-distribution arrangement, regulator revision and any dual-redundancy configuration. Match SR511 / 3BSE000863R1 and follow the approved AC450 or AC460 service procedure.
ABB identifies SR511 as a 24V/5V regulator and classifies 3BSE000863R1 as a power supply. Its role is DC/DC voltage regulation in the documented Advant controller power arrangement.
No. A power figure alone does not establish the permitted current at every operating condition. Use the applicable regulator documentation and installed load requirements; do not derive an acceptance limit solely by dividing 310 W by 5 V.
The controller documentation lists several complete power-supply arrangements. Those cabinet-level options do not replace the SR511 24V/5V identification. Trace the actual supply path and approved wiring before connecting the regulator.
ABB documents dual redundancy with up to two SR511 regulators, but redundancy alone does not establish a live-removal procedure. Apply the service instructions for the installed cabinet and verify which supply paths remain energized.
Review the upstream supply, connector condition and connected load against the approved system documentation before attributing the symptom to SR511. Keep a record of the operating conditions and measurements so the replacement decision can be assessed.
ABB historical service literature distinguishes 3BSE000863R1 from U3BSE000863R1 refurbished and Y3BSE000863R1 repair identities. State the required supply condition explicitly and confirm the offered identity and service scope before accepting a quotation.
Allow for the published 117 mm depth, 243 mm height and 54 mm width, then check the installed mounting, ventilation and cable clearance against cabinet documentation. These dimensions do not establish a thermal rating or required cooling clearance.
No. Historical parts literature identifies the product and past service options. Confirm current condition, quantity, lead time and documentation for the specific offered SR511 unit at the time of ordering.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
