ABB SA168 3BSE003389R1 – Power Supply Unit | Advant Master DCS Platform
Engineering Background
The ABB SA168 (part number 3BSE003389R1) is a dedicated power supply module engineered for ABB’s Advant Master Distributed Control System (DCS) platform — one of the most widely deployed process automation architectures in the power generation, oil & gas, pulp & paper, and chemical industries. Designed to deliver stable, conditioned DC power to controller and I/O subsystems, the SA168 is a critical infrastructure component that underpins system uptime and signal integrity across the entire control loop.
Product Positioning
Targeted at procurement engineers and maintenance teams managing legacy Advant Master installations, the SA168 3BSE003389R1 provides a direct OEM-equivalent replacement path without requiring system reconfiguration or firmware updates. Konmask.com maintains verified stock sourced from decommissioned plant inventories and authorized distribution channels, ensuring traceability and functional reliability for critical process environments.

Engineering Advantages
- Drop-in Replacement: Direct form-fit-function substitute for failed or end-of-life SA168 units — no re-engineering required
- Stable Bus Voltage: Maintains regulated output under varying load conditions, protecting downstream I/O modules from voltage transients
- Hot-swap Compatible: Supports live insertion in redundant PSU configurations (verify with site-specific Advant Master revision)
- Long Service Life: ABB Advant Master components are rated for 15–20 year operational cycles in controlled environments
- Minimal Downtime: Pre-tested units ship ready for installation, reducing mean time to repair (MTTR) in emergency maintenance scenarios
System Architecture & Signal Flow
Within the Advant Master architecture, the SA168 PSU occupies a dedicated slot in the processor or I/O subrack. AC mains input (or DC bus feed, depending on cabinet configuration) is converted and regulated to the internal bus voltage required by the AC 450 processor module, communication boards, and field I/O cards. Redundant PSU configurations (N+1) are supported via the Advant Master backplane, with automatic load sharing and failover. The SA168 interfaces directly with the subrack backplane — no external wiring to signal terminals is required for power distribution.

Technical FAQ
Q: Is the SA168 3BSE003389R1 compatible with the AC 410 platform?
A: The SA168 is primarily specified for AC 450 subracks. Compatibility with AC 410 depends on backplane revision — contact our engineering team to confirm before ordering.
Q: Can I use the SA168 in a redundant PSU configuration?
A: Yes. Advant Master supports N+1 PSU redundancy. Ensure both units carry the same 3BSE part number for matched load sharing.
Q: What is the input voltage range?
A: Refer to the ABB 3BSE003389R1 datasheet (available upon request). Typical Advant Master PSUs accept 100–240V AC, 50/60 Hz, or 24V DC depending on cabinet configuration.
Q: Do you provide an FAT (Factory Acceptance Test) report?
A: A functional test certificate is available for units requiring documented verification. Please specify at time of order.
Q: What is the lead time for urgent orders?
A: In-stock units ship within 1–2 business days. Express DHL delivery to most destinations in 3–5 business days.
