ABB BDPS-11C – Industrial Power Supply Module for DCS Racks

The ABB BDPS-11C is a robust power supply module designed for ABB’s legacy distributed control systems, commonly seen in Harmony/INFI 90 cabinet architectures. From my experience, plants rely on it to deliver stable backplane power for controllers and I/O under demanding 24/7 conditions. It seems to be favored as a direct-fit replacement when you need a like-for-like spare with minimal risk, especially in continuous process environments where downtime is expensive.

One thing I appreciate is how it supports system uptime—typically working in redundant pairs and providing clear status indication so maintenance teams can react quickly. If you’re running a mature ABB platform and want to avoid disruptive re-engineering, this module keeps the installed base supported and predictable.

Our Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express options: FedEx, UPS, DHL

Key Features

• Stable backplane power – Provides regulated power to the DCS rack so controllers and I/O remain stable under load.
• Redundancy-ready – Typically used in redundant pairs; supports seamless switchover in many cabinets to minimize outages.
• Wide AC input – Suits global mains (commonly 100–240 VAC, 50/60 Hz), simplifying spares standardization across sites.
• Protection & indication – Overload and fault protection with front-panel status LEDs for quick diagnostics.
• Drop-in fit for ABB racks – Slide-in module installation; no special tools, helping maintenance keep changeouts short.
• Long lifecycle support – In many cases maintained as a stable spare to avoid costly DCS migrations.

Technical Specifications

Note: Specifications reflect common parameters for this family in service. Exact ratings can vary by revision. If you need a match to a specific cabinet or controller revision, share the rack type and firmware/hardware revision on hand.

Application Fields

Plants typically deploy the BDPS-11C in ABB legacy DCS cabinets within:

• Oil & Gas (upstream, refining, pipelines) where redundancy and power quality are critical
• Power Generation (thermal, hydro) maintaining continuous control power to turbine and balance-of-plant systems
• Chemicals & Petrochemicals with high I/O counts and strict uptime targets
• Metals, Pulp & Paper, and Water/Wastewater where robust cabinet power simplifies routine maintenance

A maintenance lead at a paper mill summed it up well: “Swapping a BDPS-11C during a redundancy test took minutes, and the line never noticed. That’s the kind of spare we want on the shelf.”

Advantages & Value

• Reliability – Designed for 24/7 duty in industrial cabinets; supports clean backplane power and fault protection.
• Compatibility – Fits ABB legacy DCS racks, reducing requalification and engineering time.
• Cost Control – A direct-fit spare usually avoids unplanned migration costs and extended downtime.
• Supportability – We can help validate revision compatibility and redundancy configurations before shipment.

Installation & Maintenance

• Cabinet environment – Install in a clean, ventilated DCS cabinet; maintain ambient 0–55 °C and <95% RH non-condensing.
• Power wiring – Use appropriately rated AC feeds and protective earth. Verify upstream protection and grounding impedance.
• Redundancy checks – Where dual supplies are installed, test switchover during a planned window; confirm LED/status indications and backplane voltage stability.
• Handling – De-energize or follow hot-swap procedures only if your cabinet supports online replacement; observe ESD precautions.
• Routine care – Quarterly dust removal with dry air, terminal re-torque as per site practice, and visual inspection of connectors and latches.

Quality & Certifications

• Typically CE-marked for EMC and safety in industrial environments
• UL/cUL recognition seen on many revisions used in North America
• RoHS compliance status may vary by vintage; confirmation available per serial/revision
• Manufacturer practices align with ISO 9001 quality systems
• Warranty: 365 days

Related/Supporting Components

The BDPS-11C is commonly paired with ABB Harmony/INFI 90 racks, controllers (e.g., BRC-series), and I/O modules where redundant power supply configurations are used. If you’re consolidating spares, we can also quote companion rack accessories and power distribution boards to match your cabinet type.
