Description
1. Product Introduction
2D34347G08 is the latest upgraded plug-in switching power supply of Emerson Westinghouse 2D34347 series (G05/G06/G07/G08 full pin-to-pin interchangeable), belonging to Ovation DCS Q-Line rack power module, providing stabilized 24VDC power for DPU controllers, AI/DI/AO/DO I/O cards and cabinet relay loops in thermal power, nuclear power and petrochemical SIS/ETS safety systems.
It supports N+1 redundant parallel operation and hot-swap replacement without rack power interruption during maintenance. Full metal enclosed housing with optimized forced air cooling; front panel 3 LED indicators: AC input status, DC normal output, fault alarm. Built-in high-grade EMI filter and multi-stage surge suppression circuit, compliant with UL, CE, IEC industrial safety & EMC standards for 7×24h uninterrupted continuous running.
2. Electrical Specifications
AC Input: 85～264VAC universal wide voltage, 47～63Hz global industrial grid compatible
DC Output: Regulated 24VDC; G08 optimizes internal power components vs G05/G06/G07, featuring ultra-low output ripple, superior stability under frequent no-load/full-load dynamic switching, improved high-low temperature adaptability
Full Protection: OVP overvoltage, OCP overcurrent, short-circuit auto shutdown, over-temperature thermal cut-off; instant output cutoff to protect backend DCS hardware from damage
Ambient Range
Operating temp: 0℃ ~ +60℃ (inside control cabinet)
Storage temp: -40℃ ~ +85℃
Humidity: 5%～95%RH non-condensing
3. Compatibility Information
✅ Same-series full compatibility: 2D34347-G05/G06/G07/G08 share identical outline, mounting slot and terminal definition, direct plug-and-play swap with no wiring modification needed.❌ Cross-series unavailable: Cannot replace 2B10715H01, 2D34069G01 due to different mechanical dimension and pin assignment.
4. Application Fields
Installed in Ovation DCS cabinet: boiler main control cabinet, turbine ETS trip protection cabinet, BOP auxiliary interlock cabinet of thermal power plants; conventional island control cabinet of nuclear power unit; SIS emergency shutdown cabinet for petrochemical & chemical production facilities.
