Functional Features Supports redundant parallel load sharing operation. Hot swap design allows online replacement without power interruption of cabinet. Multi-level protection includes over voltage, under voltage lockout, over current limiting, short circuit shutdown and over temperature protection. Built-in monitoring circuit collects voltage, current and temperature data and sends diagnostic information to DeltaV system. Front panel tri-color LED shows power normal, running and fault state. Internal EMI filter suppresses grid surge and high frequency noise.
Application Scenarios Installed in DeltaV main control cabinets, remote I/O cabinets and auxiliary SIS power cabinets. Used in petrochemical, pharmaceutical, thermal power, water treatment and pulp and paper industries for DeltaV DCS power supply.
Performance Parameters
- Power conversion efficiency up to 90%
- Output voltage fluctuation controlled within ±1% from no load to full load
- Microsecond level protection response under short circuit and overload fault
- Bumpless redundant switchover without voltage drop
- Ultra low output ripple
Material Composition High conductivity aluminum alloy shell with integrated heat dissipation structure, anti-oxidation and anti-corrosion treatment. Internal PCB is industrial flame retardant substrate. Core power components include industrial electrolytic capacitors, power semiconductor switching tubes and precision voltage regulation chips. Terminals adopt thick copper plating. Structural plastic parts meet high temperature flame retardant industrial standard.
Structural Characteristics Vertical plug-in rack structure matching DeltaV cabinet backplane. Compact layout saves cabinet internal space. Integrated terminal block for AC input and DC output on upper section. Passive heat sink and air duct realize fan free heat dissipation. Front panel with LED indicators and locking buckle to prevent loose contact caused by vibration. Power circuit and monitoring circuit are partitioned to reduce electromagnetic crosstalk.
Working Principle External AC power enters rectifier circuit and converts to raw DC power. Multi-stage EMI filtering and voltage regulation produce stable 24VDC power and deliver to cabinet backplane. When two modules run in redundant parallel mode, both modules share load equally. If one module fails or overheats, the remaining working module takes 100% load instantly without power interruption. On-board monitoring chips continuously sample output voltage, working current and internal temperature. Protection circuit activates and uploads fault alarm when parameters exceed threshold.
Installation Requirements Install vertically in dedicated DeltaV cabinet. Inverted, horizontal or tilted installation is prohibited. Keep sufficient upper and lower ventilation clearance. Cables and modules cannot block cooling air passages. Power wiring follows industrial voltage specifications. Protective earth wire must connect firmly to cabinet grounding bus bar. Fasten module buckle after insertion. Do not install in environment with heavy vibration, corrosive gas, conductive dust or condensation.
Use Precautions Cut off corresponding AC input power before wiring, disassembly or maintenance work. Never operate beyond rated voltage and current range. Clean dust accumulated on shell and heat dissipation air ducts periodically. Do not open sealed module shell. Replace faulty module immediately when fault LED lights up to maintain redundant reliability. Avoid frequent power on and power off cycles.
