DSSR 122 48990001-NK Advantages
ABB DSSR 122 48990001-NK Power Supply Module provides highly reliable main power supply solutions for the ABB Advant OCS distributed control system. The compact high-power integrated design can bear the full load power demand of a complete set of rack control modules, and supports parallel redundant configuration of multiple modules. When a single power supply module fails, standby modules automatically undertake all load power without power interruption, greatly improving the continuous operation safety of industrial production control links. Multi-stage EMI filtering and isolation circuits thoroughly eliminate power grid harmonics, voltage fluctuations and instantaneous surges frequently seen in factory workshops, fundamentally solving system crash, signal acquisition distortion and CPU logic misjudgment triggered by unstable power supply. The independent rapid protection mechanism can cut off power output within microseconds once internal or external short-circuit, overload and overheating faults occur, effectively avoiding chain damage to dozens of core control boards inside the rack and significantly reducing equipment maintenance and replacement costs. The hot-swap compatible design brings great convenience to daily equipment maintenance and cabinet reconstruction upgrades; technicians can directly extract and replace faulty power supply modules without halting the entire production control system, eliminating massive economic losses caused by full production line shutdown and shortening fault maintenance and production recovery cycles remarkably. The built-in intelligent full-range self-diagnosis system performs uninterrupted real-time scanning of input power parameters, output load current and internal operating temperature. Once abnormal states such as input undervoltage, output overload and internal overheating are detected, the module immediately sends exclusive fault code alarm data to the upper monitoring platform, enabling maintenance staff to quickly identify power supply hidden dangers without professional power testing instruments. The integrated metal shielding shell isolates external strong electromagnetic radiation interference generated by on-site large motors, frequency converters and high-current equipment, ensuring long-term stable and clean power supply output for all precision control hardware inside the rack. All DSSR 122 48990001-NK power supply modules are manufactured strictly in accordance with ABB unified Swiss precision production standards. Each unit undergoes high-low temperature cycle aging testing, long-duration continuous full-load power supply stability testing, mechanical vibration resistance testing and electromagnetic interference anti-disturbance verification before factory delivery, featuring consistent power conversion performance and strong interchangeability. It can be freely replaced or added during system expansion and production line renovation without modifying the original rack power distribution architecture. The ultra-wide operating temperature range adapts to high-temperature, humid and dusty harsh cabinet environments in energy, chemical and papermaking industries, with zero voltage drift, false protection or shutdown failure under 24-hour uninterrupted full-load operation.
DSSR 122 48990001-NK Applications
ABB DSSR 122 48990001-NK Power Supply Module is the core main power matching component of the ABB Advant OCS distributed control platform, widely applied in new DCS system construction and legacy control system transformation upgrading projects for thermal power plants, petrochemical production bases, pulp and paper continuous production lines, metallurgical smelting workshops, municipal sewage treatment stations and chemical fertilizer manufacturing facilities equipped with Advant OCS systems.
