1. Product Overview
2D34069G01 is Emerson Westinghouse Ovation DCS cabinet rack-mounted switching power supply, original factory dedicated power unit for Ovation old-style control rack and I/O cabinet, providing stabilized DC output power for rack CPU controller boards, multi-type I/O modules and cabinet internal relay & signal circuit in thermal power, nuclear power and petrochemical DCS control system.
It supports N+1 redundant parallel installation and hot-swap maintenance; single module failure will not cause entire rack power loss. Equipped with integrated metal housing + built-in fin heat dissipation structure; front panel fitted with main power switch, red emergency stop button and multiple LED status lamps to indicate input voltage, normal output and fault alarm separately. Built-in high-efficiency EMI filter and multi-level surge suppression circuit to resist strong electromagnetic interference from cabinet contactors, inverters and on-site high-power equipment, compliant with UL, CE, IEC industrial safety and EMC standards for 24/7 continuous heavy-load running.
2. Electrical Technical Parameters
AC Input: Wide-range AC input 85～264VAC, rated frequency 47～63Hz, compatible with global industrial power grid standard
Standard DC Output: Fixed regulated DC output (core power source for Ovation legacy rack), low output ripple, stable load performance under full-load & no-load alternating working condition
Complete Protection Circuit: OVP overvoltage protection, OCP overcurrent protection, short-circuit auto-shutdown protection, over-temperature thermal cut-off protection; output immediately cuts off under abnormal working status to protect back-end DCS controller and I/O hardware from burnout damage
Ambient Specification
Operating Temp (inside control cabinet): 0℃ ~ +60℃
Storage Temp: -40℃ ~ +85℃
Working Humidity: 5%～95%RH, non-condensing environment
3. Compatibility & Replacement Instruction
Belongs to independent 2D34 series power supply family, different from 2B10335/2B10715 series plug-in power modules; same series derivative versions share consistent mounting dimension and terminal wiring definition, direct plug-and-play interchange during field overhaul without cabinet wiring modification.
4. Application Scope
Mainly used on early-generation Ovation DCS cabinets of coal-fired unit boiler control, turbine ETS protection cabinet, BOP auxiliary interlock control system, nuclear power auxiliary control cabinet and petrochemical SIS emergency shutdown system as core stable power supply for rack control hardware and field signal acquisition modules。
