đ Product Introduction
The FCâPSUâUNI2450U V2.1 is an industrial grade universal input power supply unit built for reliable DC power delivery in automation and safety systems. It converts wideârange AC input into regulated DC outputs (25 V or 28 V depending on setup), delivering high current (up to ~50 A) with excellent efficiency. It is engineered for systems like distributed control systems (DCS), safety controllers, I/O modules, and other critical loads that require stable, faultâtolerant power.
Built with multiple safety and protection features, this PSU is designed to minimize failures due to thermal overload, voltage spikes, or short circuits. It also supports redundancy, allowing parallel or backup operation to maintain system uptime in case one unit fails. Physical design is robust for industrial environments, with sufficient cooling, durable wiring/connectors, and is often mounted in control cabinets or power racks.
đ Applications
Typical environments and uses include:
-
Process control centres (oil & gas, chemical, refining)
-
Safety instrumented systems (e.g. emergency shutdown, fire & gas detection)
-
Automation panels with heavy I/O and controller loads
-
Systems requiring redundant or backup power supplies
-
Communication racks and module clusters in industrial plants
-
Any industrial setting with wide input voltage variation or harsh environment
â Advantages
-
Able to accept a wide input voltage range, so works in areas with unstable AC mains
-
High current output supports many modules or heavy loads in control and safety systems
-
Low ripple and noise help preserve signal integrity for sensitive electronics
-
Multiple protection features reduce risk of damage and increase lifespan
-
Supports redundancy configuration, improving system availability and safety
-
Efficiency is good, reducing waste heat and power loss
-
Physical size and weight balanced between power and manageability

â Frequently Asked Questions (10 QA)
Here are 10 fresh Q&A items about FCâPSUâUNI2450U V2.1, clear and practical, each ending with a blank line.
Q1: What is the nominal output current in 25V mode?
A1: In 25V mode the PSU can provide about 48âŻA under typical operating conditions (ambient around â5°C to +50°C).
Q2: What happens when the input voltage drops low?
A2: The unit has undervoltage protection; below certain input thresholds the power may reduce or shut down to prevent damage.
Q3: Can this PSU be used in a redundant pair?
A3: Yes. Two units can be configured in parallel or as backup to increase reliability; load sharing and fault tolerance are supported.
Q4: Is there temperature derating?
A4: Yes. As ambient temperature rises above rated fullâload range, the output current capability is reduced according to derating curves to protect the unit.
Q5: What voltage ripple and noise performance does it have?
A5: Ripple and noise are typically under 40 mV peakâtoâpeak, which is acceptable for most control and I/O electronics.
Q6: What sort of protection circuits are included?
A6: It includes overvoltage protection, short circuit protection, and over temperature protection among others.
Q7: What is the holdâup time?
A7: The PSU can maintain output for about 100 milliseconds at full load after a brief AC input interruption.
Q8: How heavy and large is this unit?
A8: It has dimensions of around 420.5 Ă 140 Ă 90 mm, and its weight is about 5.7 kg.
Q9: In what operating temperature range is it rated for full power?
A9: Full load operation is generally valid from about â20°C up to +50°C. Outside that range, derating applies.
Q10: What are the certification and safety standards it meets?
A10: It is certified to multiple standards such as UL508, CE, TUV, CSA, and supports dual overvoltage protection, making it suitable for industrial and safety related systems.
