IEPAS02 Advantages
ABB IEPAS02 provides high-stability redundant rack AC power supply solution for ABB Bailey INFI 90 series distributed control systems. Stable operating performance. High-efficiency isolated power conversion circuit outputs low-ripple stable DC voltage for all rack plug-in functional modules, independent multi-channel power distribution avoids cross-card voltage fluctuation interference; dual redundant parallel seamless switching ensures uninterrupted power supply of the whole rack under single power supply failure condition. Built-in full-time power parameter self-check function timely uploads undervoltage, overload and overtemperature early warning alarms, fully meets the long-term uninterrupted stable power supply demand of large power plants and chemical DCS control stations. Strong environmental adaptability. Reinforced anti-vibration industrial PCB substrate and high-temperature resistant power conversion components support 24-hour continuous full-load operation under humid, dusty, high-temperature and strong electromagnetic interference power plant cabinet environments. Excellent anti-interference capability. Complete input-output galvanic isolation separates external industrial AC power grid loop and internal DCS low-voltage signal power supply loop, effectively absorbs power grid lightning surge and voltage fluctuation interference, fundamentally avoids module abnormal restart, sampling signal distortion and intermittent communication disconnection caused by unstable on-site power supply and frequency converter EMI noise. Perfect system compatibility. Standard INFI 90 rack power matching interface is fully compatible with all mainstream ABB Bailey INFI 90 series functional modules including main processor boards, various analog/digital I/O modules, all termination units and system communication interface cards, providing unified reliable operating power for all hardware of the whole control rack. Convenient maintenance design. Rack-mounted power unit equipped with front panel power operation, load and fault status indicator lights, supports online hot-swap redundant maintenance without cutting off power of the whole cabinet, simplifies on-site AC input power cable inspection, full-load power parameter test and rapid replacement of spare power supply. Industrial durable reliability. Produced in strict accordance with ABB Bailey INFI 90 power industry DCS power supply standards, passed long-term full-load temperature cycle aging test, built-in multi-level cascaded safety protection mechanism, full-time self-diagnosis covering all DC output channels and bus links, fully meets the long-term stable centralized power supply operation demand of on-site ABB Bailey INFI 90 control systems.
