Core advantages and technical highlights

High – efficiency power conversion

The FC-PSU-UNI2450U boasts an impressive efficiency of up to 94%, minimizing energy losses during power conversion. This not only helps in reducing operational costs but also contributes to environmental sustainability. In energy – intensive industries like steel manufacturing or data centers, where large amounts of power are consumed, the high – efficiency power conversion of this unit can lead to significant savings over time.

Wide input voltage range

With an input voltage range of 90 – 264 V AC, the power supply unit can adapt to different power grid conditions. This versatility is especially beneficial in regions with fluctuating power supplies or in industrial setups where multiple power sources may be used. It ensures that the connected industrial control systems remain operational without disruption, regardless of minor voltage variations in the input power.

Selectable output voltages

The ability to select between 25 V DC @ 48 A or 28 V DC @ 43 A, along with a standard 24 V DC output (adjustable ±1%), provides flexibility in powering different types of industrial devices. Some industrial sensors and actuators may require specific voltage levels for optimal performance, and the FC-PSU-UNI2450U can meet these diverse requirements without the need for additional voltage converters or complex wiring modifications.

Robust protection mechanisms

Equipped with dual overvoltage protection, short – circuit protection, and over – temperature protection, the power supply unit safeguards connected devices from potential electrical hazards. In industrial environments, electrical faults such as short circuits or overvoltage situations can occur due to various factors like lightning strikes, equipment malfunctions, or incorrect wiring. The protection mechanisms in the FC-PSU-UNI2450U quickly detect and respond to such faults, preventing damage to sensitive industrial control components and ensuring the safety and reliability of the overall system.

Real – time monitoring and control

The unit features independent regulation circuits for output voltage limitation and a relay that de – energizes when the output voltage drops below 22 V DC. This real – time monitoring and control functionality allows operators to continuously monitor the power supply status. In critical industrial processes, such as pharmaceutical manufacturing or oil refinery operations, where uninterrupted power is crucial, these monitoring features enable early detection of power issues, allowing for prompt corrective actions to be taken.

Typical application scenarios

Manufacturing plants

In manufacturing plants, the FC-PSU-UNI2450U powers a variety of equipment, including programmable logic controllers (PLCs), motor drives, and robotic arms. For example, in an automotive assembly line, PLCs control the movement of conveyor belts, robotic arms perform tasks like welding and painting, and motor drives power the motors that move the assembly jigs. The stable power supply from the FC-PSU-UNI2450U ensures the precise and synchronized operation of all these devices, minimizing production errors and downtime.

Chemical processing facilities

Chemical processing plants have complex control systems that monitor and regulate chemical reactions, temperature, pressure, and flow rates. The FC-PSU-UNI2450U provides power to the sensors, transmitters, and control valves in these systems. For instance, in a petrochemical refinery, pressure transmitters send data to the control system about the pressure inside reactors, and control valves adjust the flow of chemicals. The reliable power supply from this unit is essential for accurate monitoring and control, preventing potential safety hazards and ensuring smooth chemical processes.

Power generation stations

In power generation stations, whether they are coal – fired, gas – fired, or hydro – electric, the FC-PSU-UNI2450U powers the control systems that manage the generation, transmission, and distribution of electricity. It supplies power to the supervisory control and data acquisition (SCADA) systems, which monitor and control various aspects of the power generation process, such as turbine speed, generator voltage, and grid frequency. A stable power supply is critical in these applications to maintain the integrity of the power grid and prevent blackouts.

Connect the output cables to the appropriate devices, ensuring that the voltage settings on the power supply unit match the requirements of the connected devices.

Ground the power supply unit according to local electrical codes to prevent electrical hazards.

Commissioning

Before powering on the unit, double – check all the connections to ensure they are secure and correct.

Power on the input power source and verify that the power supply unit is functioning properly. Check the status LEDs (if available) to confirm normal operation.

Use a multimeter to measure the output voltage and ensure that it is within the specified tolerance (±1% for the 24 V DC output). Adjust the output voltage if necessary using the built – in adjustment mechanism.

Connect a small load to the output and verify that the power supply unit can deliver the rated current without significant voltage drops.

Maintenance suggestions

Perform regular visual inspections to check for any signs of overheating, such as discoloration of the unit or melting of cable insulation. Also, look for loose connections or signs of corrosion on the terminals.

Use a power quality analyzer to periodically check the input and output power quality. Monitor parameters such as voltage, current, frequency, and harmonic distortion to detect any potential issues early.

Clean the unit regularly to remove dust and debris, especially in dusty industrial environments. Dust accumulation can affect the heat dissipation of the unit and potentially lead to overheating.
