1. Petrochemical Refinery DCS Cabinet Power Supply

Application

Serves as core DC-DC power module for DeltaV S-series DCS cabinets in crude oil refineries. Converts 24VDC input to 5VDC controller power and 12VDC I/O power, adopting dual redundant parallel configuration for main controllers and analog/digital I/O modules.

Effect

Suppresses grid voltage fluctuations from frequent pump startup; ultra-low ripple output ensures stable system operation. Supports hot-swap maintenance, greatly reducing cabinet downtime and realizing long-term trouble-free operation.

2. Thermal Power Plant BMS Safety System

Application

Applied to 300MW unit boiler BMS and DeltaV SIS system, providing stable power for flame detection, furnace pressure monitoring and emergency shutdown logic modules.

Effect

Wide temperature tolerance adapts to high-temperature cabinet environments. Built-in current limiting and short-circuit automatic recovery functions prevent equipment damage and false protection trips, improving unit operational stability.

3. Chemical Plant ESD Emergency Shutdown System

Application

Deployed in fine chemical workshop ESD cabinets, powering safety interlock, pressure and temperature alarm modules for DeltaV S-series redundant control systems.

Effect

Redundant power design eliminates single-point failure risks. Precise voltage output guarantees accurate 4–20mA sensor signal acquisition, meeting SIL2 safety power supply standards and avoiding system abnormal shutdowns.

4. Urban Sewage Treatment Automation System

Application

Used in sewage plant central control cabinets to supply power for flow, liquid level, pH monitoring I/O modules and auxiliary control units of production facilities.

Effect

Low static power consumption reduces cabinet heat accumulation. Excellent anti-interference capability resists on-site inverter noise, supporting standardized power distribution and convenient unified maintenance.

5. Coastal Natural Gas Tank Monitoring System

Application

Installed in outdoor explosion-proof cabinets of coastal gas terminals, matching DeltaV tank monitoring system to power level, pressure and fire & gas detection modules.

Effect

Adapts to humid and salt-fog coastal environments. Hot-swap inrush current limiting prevents bus voltage drop, ensuring long-term stable and continuous safety monitoring.

General Application Advantages

Professional adaptation: Dedicated power supply for DeltaV S-series controllers and I/O modules with full compatibility.

Flexible redundancy: Supports parallel connection for load expansion and hot standby redundant power supply.

Convenient maintenance: Allows online hot swap without system shutdown.

Comprehensive protection: Equipped with overvoltage, undervoltage, overcurrent and short-circuit protection, suitable for high-reliability continuous industrial operation scenarios.
