DSSR 170 48990001-PC Advantages
ABB DSSR 170 48990001-PC Power Supply Unit provides high-reliability main power supply solution for ABB Advant OCS distributed control system. The high-power integrated power supply design can bear the full load power demand of a complete set of rack control modules, and supports multiple units parallel redundant operation. When one power supply fails, other standby power supplies automatically undertake all load power without power interruption, greatly improving the safety and continuous operation performance of industrial production control. Multi-stage EMI filtering and isolation circuit thoroughly eliminate power grid harmonic, voltage fluctuation and instantaneous surge interference common in factory workshops, fundamentally solving system crash, signal acquisition distortion and CPU logic misjudgment caused by unstable power supply. The complete independent protection mechanism can quickly cut off power output within microseconds once short circuit, overload, overheating and other faults occur inside or outside the module, effectively avoiding chain damage of dozens of core control boards in the rack and greatly reducing equipment maintenance and replacement costs. The hot-swap compatible design brings great convenience for daily equipment maintenance and cabinet reconstruction upgrading; technicians can directly pull out and replace faulty power supply units without stopping the whole production control system, avoiding huge economic losses caused by full production line shutdown and greatly shortening fault maintenance and production recovery cycle. The built-in intelligent full-range self-diagnosis system runs 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 will immediately send exclusive fault code alarm information to the upper monitoring platform, maintenance personnel can quickly judge 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 170 48990001-PC power supply units are produced strictly in accordance with ABB unified Swiss precision manufacturing standards, each unit passes high-low temperature cycle aging test, long-time continuous full-load power supply stability test, mechanical vibration resistance test and electromagnetic interference anti-disturbance verification before factory delivery, with consistent power conversion performance and strong interchangeability, which can be freely replaced and added during system expansion and production line reconstruction 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, and there is no voltage drift, false protection or shutdown failure under 24-hour uninterrupted full-load operation.
DSSR 170 48990001-PC Applications
ABB DSSR 170 48990001-PC Power Supply Unit is the core main power matching component of ABB Advant OCS distributed control platform, widely applied to new DCS system construction and old control system transformation upgrading projects of thermal power plants, petrochemical production bases, pulp and paper continuous production lines, metallurgical smelting workshops, municipal sewage treatment stations and chemical fertilizer manufacturing factories equipped with Advant OCS systems. As the energy supply core of the whole distributed control cabinet, it converts industrial AC power into standard DC bus voltage required by all modules in the rack, provides stable continuous power guarantee for CPU operation, signal collection, data communication and storage recording of the DCS system, and supports redundant parallel backup configuration to realize non-stop power supply for important continuous production working conditions. The product is applicable to complete set assembly of new project DCS control cabinets, power system replacement and redundant expansion of aging Advant OCS control systems, intelligent factory digital transformation and safety backup control system construction projects, acting as the indispensable energy supply carrier supporting the long-term safe and stable operation of all functional modules inside the Advant OCS distributed control system.
