2B10715H01
2B10715H01 is Emerson Westinghouse Ovation DCS rack plug-in switching power supply, dedicated power unit for Ovation controller rack and I/O cabinet, used to supply stabilized 24VDC working power for main controller cards, all kinds of I/O modules and cabinet internal signal relay loops in thermal power, nuclear power and petrochemical DCS control system.
Description
1. Product Overview
2B10715H01 is Emerson Westinghouse Ovation DCS rack plug-in switching power supply, dedicated power unit for Ovation controller rack and I/O cabinet, used to supply stabilized 24VDC working power for main controller cards, all kinds of I/O modules and cabinet internal signal relay loops in thermal power, nuclear power and petrochemical DCS control system.It supports N+1 redundant parallel hot plug operation to realize fault backup; single power module breakdown will not cause full rack power drop. Adopts integrated metal sealed casing with built-in high-efficiency heat sink; front panel is equipped with multi-group LED status indicators for input power, output normal and fault alarm respectively. Internal high-performance EMI filter and multi-stage surge suppression circuit are configured to resist strong electromagnetic interference from cabinet contactors, inverters and high-power field equipment, complying with UL, CE, IEC industrial safety & EMC standards for 7×24h uninterrupted continuous operation.
2. Electrical Technical Parameters
AC Input: Universal wide-range input 85VAC～264VAC, frequency 47Hz～63Hz, compatible with global industrial power grid specification
DC Rated Output: Regulated 24VDC fixed output; optimized circuit design for low ripple output, stable load characteristic under full-load/light-load switching
Full Protection Functions: OVP overvoltage protection, OCP overcurrent protection, short-circuit automatic cutoff protection, over-temperature thermal shutdown protection; output cuts off immediately when abnormal load occurs to protect rear-end Ovation I/O and controller hardware
Ambient Conditions
Operating temperature (cabinet internal): 0℃ ~ +60℃
Storage temperature: -40℃ ~ +85℃
Working humidity: 5%～95%RH, non-condensing environment
3. Version Compatibility & Replacement
2B10715H01 belongs to independent 2B10715 series power supply, different from 2B10335(G05/G06/G09) series; consistent installation size and pin definition with same-series derivative models, direct plug-and-play interchange for on-site maintenance replacement without modifying cabinet wiring and slot structure.
4. Application Fields
Mainly installed on Ovation DCS control cabinets of coal-fired power unit boiler control, turbine ETS protection cabinet, auxiliary BOP interlock control, nuclear power auxiliary control system and petrochemical SIS emergency shutdown system, serving as core stable power supply for rack control hardware and field signal acquisition modules.
