Product Description
Product Overview
The Emerson VE5109 DC to DC System Power Supply is designed to power DeltaV controllers and I/O interfaces using either 12V DC or 24V DC bulk power. It supplies the required 5V and 3.3V DC power to controllers and delivers 12V DC power to I/O interfaces. This high-efficiency power supply supports flexible mounting configurations and robust environmental tolerances for industrial applications.
Key Features
• Supports both 12V DC and 24V DC bulk power inputs.
• Provides stable power output to DeltaV controllers and I/O interfaces.
• Built-in protection against overvoltage, inrush current, and internal faults.
• Compact and flexible mounting options for different DeltaV power carriers.
• LED indicators for real-time power and error status.
