Description

Providing stabilized backplane logic power, the ABB DSSR122 functions as a high-capacity power supply module within the legacy Advant Master (Advant OCS) control system architecture. This module is engineered to accept a primary input range of 18V to 30V DC and convert it into a highly regulated 5V DC output rated at up to 40A. Built to withstand the electrical rigors of heavy industrial processes, the hardware delivers consistent, low-ripple power directly to the rack backplane to ensure continuous operation of processing units and communication interfaces.

Key Features

High Current Output: Delivers continuous 5V DC logic power at 40A to support dense multi-module configurations.
Wide DC Input Tolerance: Operates reliably across a fluctuating 18V to 30V DC input window, mitigating standard main-line voltage drops.
System Integration: Native mechanical and electrical compatibility with the ABB Advant Controller rack assemblies.
Rugged Enclosure: Industrial-grade metal housing designed for effective passive heat dissipation and structural protection.

Applications

ABB Advant Controller 410 (AC410) and Advant Controller 450 (AC450) process control stations.
Centralized cabinet installations requiring high-amperage 5V DC logic feeds.
Continuous process industries including paper mills, power generation, and chemical refinement plants.

Empirical Engineering Insights

Alternative Models & Compatibility

The DSSR122 acts as a direct-replacement power assembly. Ensure that physical backplane guides and dynamic sub-rack keying elements are aligned correctly with the unit chassis prior to insertion to prevent guide-pin damage on older OCS backplanes.

Application Pitfalls & Engineering Notes

Under a full 40A load, backplane contact resistance must be minimized. Oxidation on aging rack connectors can cause high-resistance points, leading to local voltage drops and thermal stress. Clean the backplane contacts with approved non-residue contact cleaners during standard maintenance cycles.

Commissioning & Wiring Tips

To accommodate the primary input current draw under peak startup conditions, ensure that the feeding 24V DC cabling is correctly dimensioned to prevent transient voltage sags. Use multi-strand copper conductors with correct ferrule terminations at the terminal block.

Installation Guidelines

CRITICAL WARNING

Isolate and lock out all primary and secondary DC supply sources before attempting mechanical installation or removal of this unit. High-current arcing hazard exists at the backplane interfaces when mounting under live electrical loads.

Inspect the card-edge backplane connectors on the DSSR122 for bent contacts, debris, or dust accumulation.

Align the module carefully with the sub-rack card guides, pushing the assembly firmly into place until the front locking mechanism is fully engaged.

Connect the input wires to the designated primary power terminals, verifying correct polarity (18-30V DC input).

Energize the primary source and measure output logic levels at the terminal monitoring points to verify stable 5V DC delivery.

#Advant Master #PLC Power Supplies

What is the primary output rating of the DSSR122 unit?

The module delivers a stabilized 5V DC output with a maximum current rating of 40A, designed to supply logic power to the rack backplane.

What is the acceptable DC input voltage range?

The DSSR122 operates with a wide primary input range between 18V DC and 30V DC, allowing for stable operations during standard industrial supply fluctuations.

Does the DSSR122 require forced-air cooling in the panel?

The module utilizes natural convection cooling. However, users must maintain adequate vertical clearance inside the electrical cabinet to prevent excessive heat buildup under heavy loads.

Can this unit be hot-swapped while the system is under load?

No. Hot-swapping is not recommended due to high-current arcing hazards at the system backplane connectors. The primary supply must be fully de-energized before mounting or extracting.
