FAQs

What is SFB technology in this power supply?

SFB (Selective Fuse Breaking) technology allows the power supply to reliably trigger standard circuit breakers even with high inrush currents, ensuring that only the faulty circuit is disconnected while the rest of the system remains operational.

How do I adjust the output voltage?

The output voltage can be adjusted using a small potentiometer located on the front of the unit. Rotate it carefully to set the desired voltage between 24V and 29.5V. Refer to the manual for precise instructions.

What is the "Power Boost" feature?

"Power Boost" provides a temporary power reserve during startup of heavy loads, ensuring a smooth and reliable start for devices with high inrush currents.

Can this power supply be used worldwide?

Yes, with its wide AC input voltage range of 85-264V AC and an AC input frequency of 45-65 Hz, it is suitable for use in most countries worldwide.

What is the MTBF rating?

The Mean Time Between Failures (MTBF) for this unit is 1,433,000 hours, indicating a very high level of reliability and a long operational lifespan.

How does the preventive function monitoring work?

The unit monitors its own operational status and critical parameters. If a potential issue is detected that could lead to a failure, it activates LED indicators or a relay output to alert the user before a complete breakdown occurs.

Can I connect multiple units in parallel?

Yes, Phoenix Contact offers parallel switch bars for this series, allowing you to connect multiple units in parallel to increase output current or provide redundancy.

Troubleshooting

Unit does not power on

Verify AC input voltage is within the 85-264V range. Check all screw terminal connections for proper seating and tightness. Ensure the circuit breaker protecting the input is engaged.

Output voltage is incorrect or unstable

Check the output voltage adjustment potentiometer and ensure it is set to the desired level. Verify the input voltage is stable and within specifications. Clean any dust from ventilation slots.

SFB technology not triggering as expected

Ensure the connected loads are compatible with SFB technology and that the overload is significant enough to trigger the protection. Refer to the SFB technology section in the full product manual.

Preventive function monitoring indicates a fault

Consult the product manual to interpret the specific LED error code. Investigate the related system component indicated by the error and take corrective action.

Pros and Cons

Pros

  • High system availability due to SFB technology.
  • Reliable startup for heavy loads with "Power Boost".
  • Proactive error detection through preventive function monitoring.
  • Flexible and remote monitoring capabilities.
  • Global usability with wide-range input voltage.
  • Long operational lifespan with high MTBF.

Cons

  • Requires specific input voltage ranges for optimal function.
  • SFB technology may require understanding for initial setup.
  • Not designed for intermittent or fluctuating load conditions without proper planning.
  • Limited to 84W total power output.
  • Cooling is passive, requiring adequate ambient airflow.

Setup, Compatibility & Care

Setup:

  1. Mounting: Mount the power supply vertically on a DIN rail in a control cabinet. Ensure sufficient space around the unit for airflow.
  2. Wiring: Connect the AC input voltage (85-264V AC) to the designated screw terminals. Connect the 24V DC output to your load using the output screw terminals. Ensure all connections are secure.
  3. Configuration: Adjust the output voltage if necessary using the potentiometer for voltage balancing or battery charging applications. Consult the product manual for precise adjustment procedures.

Compatibility:

  • Compatible with standard 24V DC control systems, PLCs, sensors, actuators, and other industrial equipment.
  • Wide AC input range (85-264V AC) ensures compatibility with various power grids worldwide.
  • Use with Phoenix Contact QUINT series accessories for enhanced functionality and redundancy.

Care:

  • Cleaning: Periodically clean the unit with a dry or slightly damp cloth. Ensure the unit is disconnected from power before cleaning.
  • Ventilation: Maintain clear ventilation paths around the unit to prevent overheating. Avoid dust accumulation.
  • Monitoring: Regularly check the LED fault indicators for any warning or error states.
