48VDC 5A Redundant DIN Rail Power Supply | 240W | Internal ORing Diode | 120/230VAC Input | XCSF240DP

48VDC 5A Redundant DIN Rail Power Supply

The XCSF240DP is a 240W industrial DIN rail power supply designed for redundant 48VDC power systems where equipment availability and continuous operation are critical. It provides regulated 48VDC power at 5A continuous output and includes a factory-installed internal ORing diode, simplifying the design of redundant power systems without requiring a separate external ORing diode.

With adjustable 45–55VDC output, high temporary overload capability, DC OK monitoring, and comprehensive electrical protection, the XCSF240DP provides a reliable power solution for critical industrial automation, communication, control, and monitoring applications.

What Does This Power Supply Do?
The XCSF240DP converts 120VAC or 230VAC input power into regulated 48VDC power capable of continuously supplying up to 5A at 45°C.

The output voltage can be adjusted from 45–55VDC, providing flexibility for equipment requiring a specific operating voltage or compensation for voltage drop in DC distribution wiring.

The XCSF240DP also accepts 300–345VDC input.

Most importantly, the XCSF240DP incorporates an internal ORing diode for redundant parallel operation. When properly configured with another compatible redundant supply, failure of one power supply does not necessarily interrupt 48VDC power to the critical load.

Why Use a Redundant 48VDC Power Supply?
A single power supply can become a single point of failure in an industrial control or communication system.

If that supply fails, equipment powered by the 48VDC circuit may immediately shut down, potentially causing loss of communications, monitoring, control functions, or machine operation.

A properly designed redundant power system uses multiple power supplies so another supply can continue supporting the critical load if one power supply fails.

The XCSF240DP simplifies redundant system design by incorporating the ORing diode required for redundant operation directly into the power supply.

What Problem Does This Solve?
Unexpected loss of 48VDC power can cause:
• Loss of Industrial Communications
• Industrial Ethernet Network Shutdown
• Control System Shutdown
• Loss of Remote Monitoring
• Machine or Process Interruption
• Loss of Critical Electronic Equipment
• Production Downtime

The XCSF240DP provides a practical way to build redundancy directly into a 48VDC power system, reducing the risk that failure of a single power supply will interrupt power to critical equipment.

Why Choose the XCSF240DP?
The XCSF240DP combines 240W of regulated 48VDC power with built-in redundancy capability in a compact industrial DIN rail package.

Its factory-installed internal ORing diode eliminates the need for a separate external ORing diode when configuring redundant power, helping reduce component count, wiring complexity, and panel space.

The XCSF240DP also provides substantial temporary overload capability. Its 5A continuous output can increase to 7.5A for more than 30 seconds, providing additional capacity for temporary overload and startup conditions.

The integrated DC OK dry-contact alarm allows a PLC or monitoring system to detect a power supply problem even if the redundant supply continues supporting the load.

Need More Power or Redundancy?
The XCSF240DP supports parallel operation and includes the internal ORing diode required for redundant parallel configurations.
