ABB SA167 3BSE003390R1 – Power Supply Unit for Advant OCS / 800xA Systems
Product Overview
The ABB SA167 3BSE003390R1 is a high-performance switch-mode power supply module designed for ABB Advant OCS (Operator Control Station) and System 800xA distributed control platforms–1. This unit serves as the primary power distribution component within I/O subracks, control cabinets, and fieldbus termination assemblies, converting AC mains into a regulated 24 VDC bus for downstream automation equipment-.
As a member of the SA167 series, this module addresses a fundamental challenge in industrial automation: maintaining stable, low-ripple DC power under fluctuating load conditions and harsh environmental stresses-. The 3BSE003390R1 supports hot-swap replacement without system shutdown, a critical feature for continuous process applications where unplanned downtime carries significant cost penalties-1. Built for ABB’s Advant Master and S800 I/O ecosystems, this power supply ensures control modules, communication adapters, and field devices receive clean, uninterrupted power—the foundation of reliable system operation-.

ABB SA167 3BSE003390R1
Key Features and Benefits
Stable, Regulated DC Output
The ABB SA167 delivers 24 VDC at 25 A with ripple and noise below 100 mVpp (20 MHz bandwidth), ensuring sensitive I/O modules and communication processors receive power within their specified tolerance windows-. Active power factor correction (>0.95) minimizes harmonic reflection back onto the facility grid-.
Hot-Swap Capability
The module’s draw-out mechanical design allows field replacement without powering down the subrack-1. For redundant configurations—particularly in I/O subracks 2 and 3—a second 3BSE003390R1 can be installed alongside the primary unit to provide true parallel redundancy-.
Comprehensive Protection Circuitry
Built-in overvoltage, overcurrent, short-circuit, and overtemperature protection safeguards both the power supply and downstream loads from fault conditions-. The unit operates with fanless convection cooling, eliminating a common failure point in dust-laden industrial environments-.
Wide Environmental Tolerance
Rated for operation from -20°C to +50°C, the SA167 performs reliably in applications ranging from cold storage facilities to high-ambient process areas-5-24. Its IP20 enclosure provides protection against solid objects larger than 12.5 mm, suitable for protected control room and cabinet installations.
Energy-Efficient Operation
With conversion efficiency exceeding 89% at rated load, the module reduces both energy consumption and cabinet heat dissipation requirements, contributing to lower operational costs and simplified thermal management-.

Installation and Maintenance
The 3BSE003390R1 installs directly into standard ABB Advant OCS subracks via rear-panel connectors-1. No additional cabling is required beyond the AC input termination and DC output bus connections. A spare 15 A fuse (part number 5672827-15) is specified for field replacement–3.
Routine maintenance is limited to periodic inspection of input voltage stability and output voltage measurement under load. The hot-swap design means the unit can be exchanged during scheduled maintenance windows—or in response to a fault alarm—without interrupting process control operations-1. When deploying redundant configurations, both units should be from the same production batch to ensure matched output characteristics.
