DSSB145 Advantages
ABB DSSB145 DC/DC Converter delivers reliable internal power conversion solutions for the ABB Advant OCS distributed control system. The integrated multi-channel power output layout can supply stable working voltage for all types of control boards inside the rack simultaneously, simplifying the internal power wiring layout of the control cabinet and reducing hidden dangers of wiring faults. The multi-stage isolation and filtering circuit thoroughly filters high-frequency ripple and voltage fluctuation generated by factory unstable power grid, completely avoiding abnormal operation, calculation errors and signal acquisition distortion of precision CPU and I/O modules caused by poor power quality. Every power output channel is equipped with an independent automatic protection circuit; once short circuit, overload or overvoltage occurs on any branch, the module only disconnects the faulty single channel while keeping other normal power channels running continuously, which effectively prevents large-area damage to multiple core control boards and greatly reduces equipment maintenance costs. The hot-swap compatible design brings prominent convenience for daily power equipment maintenance and cabinet reconstruction; technicians can directly extract and replace defective DC-DC converter modules without halting the entire production control system, eliminating massive economic losses from full production line shutdown and significantly shortening fault troubleshooting and production recovery cycles. The built-in intelligent all-round self-diagnosis system uninterruptedly scans input power parameters, each channel output load and internal operating temperature. Once abnormal conditions such as input undervoltage, output overload and internal overheating are detected, the module instantly transmits exclusive fault alarm data to the upper monitoring platform, allowing maintenance staff to quickly judge power faults without additional professional power testing instruments. The integral metal shielding shell isolates external electromagnetic radiation interference emitted by on-site high-power motors and frequency converters, ensuring long-term stable and clean power supply for all core control hardware. All DSSB145 DC/DC converters are manufactured strictly in accordance with ABB’s 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 during system expansion and production line renovation without adjusting the original rack power distribution framework. The ultra-wide operating temperature range adapts to high-temperature, humid and dusty harsh cabinet environments within chemical, energy and papermaking industries, with zero output voltage drift or protection misoperation under 24-hour uninterrupted full-load operation.
DSSB145 Applications
ABB DSSB145 DC/DC Converter serves as the core internal power matching component for the ABB Advant OCS distributed control platform, widely deployed in new DCS system construction and legacy control system transformation projects for thermal power plants, petrochemical production bases, pulp & paper continuous production lines, metallurgical smelting workshops, municipal sewage treatment stations and chemical fertilizer manufacturing facilities equipped with Advant OCS systems. It is specially used to convert the main DC power input of the system rack into multiple groups of precise low-voltage power required by CPU modules, communication processors, memory boards and digital & analog signal input/output modules, providing stable and isolated power guarantee for all core automatic control hardware inside the cabinet. The product applies to complete cabinet assembly for new industrial projects, power system renovation and upgrading of aging Advant OCS control systems, intelligent factory process control reconstruction and redundant backup control system construction projects, acting as the essential power conversion carrier supporting the continuous and safe operation of all functional modules inside the Advant OCS distributed control system.
