Functional Features: Convert AC input to stable 24VDC power to supply DeltaV rack and I/O modules. Hardware overvoltage, overcurrent, short circuit and overtemperature protection. Support redundant parallel installation for uninterrupted power supply. Front panel LED indicators for power running and fault status. Built-in power monitoring circuit to send power fault alarm to DeltaV system. Overload automatic shutdown protection to avoid module damage.
Application Scenarios: DeltaV DCS control cabinet power supply for petrochemical plant, power plant DCS rack power supply, refinery process control cabinet power unit, oil & gas plant redundant control cabinet power, water treatment DCS rack power supply.
Performance Parameters: High power conversion efficiency under continuous load operation. Stable 24VDC output voltage under load fluctuation. Fast hardware protection response under fault condition. Long service life for 24/7 continuous cabinet operation.
Material Composition: Metal coated housing with EMC shielding. High power rectifier and switching semiconductor components. Aluminum alloy heat sink for heat dissipation. Electrolytic and film capacitors. FR4 power printed circuit board. Flame retardant plastic front panel with LED indicators.
Structural Features: Plug-in power module for DeltaV rack dedicated power slot. Front panel with power OK and fault LED indicators. Built-in cooling air channel for heat dissipation. Internal circuit partitions separate high voltage AC input and low voltage DC output. High current terminal blocks for AC input and DC output connection. Extraction handle for module replacement.
Working Principle: AC mains power enters VE3006 module. Switching power circuit converts AC power to regulated 24VDC DC power. The DC power supplies DeltaV rack backplane and all plug-in I/O modules. Built-in monitoring circuit continuously detects output voltage, output current and internal temperature. When overvoltage, overcurrent, overtemperature or short circuit occurs, hardware protection circuit triggers and cuts off output power, meanwhile sends fault alarm signal. Redundant dual power configuration realizes automatic switchover when one power supply fails.
Installation Requirements: Install VE3006 into dedicated power slot of DeltaV I/O rack. Connect AC input cable to module power terminal. Separate high voltage AC input wiring and low voltage signal wiring. Ensure cabinet ventilation meets heat dissipation requirement. Complete protective earth connection of module and rack chassis. Configure dual redundant power supply for critical process control rack.
Usage Notes: Verify AC input voltage matches module rated specification before power on. Check LED power status indicator after power energization. Cut off AC input power before removing power module. Do not open module housing. Inspect cooling air passage for dust accumulation periodically.
