Product Information

Full details

This Phoenix Contact QUINT DC power supply unit is designed for industrial applications requiring a reliable and efficient 24V DC output from a 3-phase AC input. It's ideal for engineers and technicians in automation and control systems who need robust power delivery. A key benefit is its SFB Technology, offering rapid circuit breaker tripping for enhanced safety. The primary caveat is its requirement for a 3-phase AC input, limiting its use in single-phase systems.

Extended Product Information

FAQs

What type of AC input does this power supply require?

This power supply requires a 3-phase AC input voltage between 320V and 575V.

What is the continuous output current capability?

The unit provides a continuous output current of up to 20 Amps, with a total power output of 480 Watts.

What is SFB Technology?

SFB (Selective Fuse Breaking) Technology allows the power supply to actively detect short circuits and trigger miniature circuit breakers extremely quickly, ensuring reliable system operation and safety.

Can this unit be used with a single-phase AC input?

No, this unit is specifically designed for 3-phase AC input and cannot be used with a single-phase supply.

What is the operating temperature range?

The unit can operate reliably in ambient temperatures ranging from -25°C to +70°C.

How is the unit mounted?

It is designed for easy mounting on a standard 35mm DIN rail.

What is the expected lifespan of this power supply?

The unit boasts a high Mean Time Between Failures (MTBF) of 900,000 hours, indicating a very long and reliable operational life.

Troubleshooting

Unit does not power on (no output voltage)

Verify that the 3-phase AC input voltage is within the specified range (320-575V AC) and correctly wired to L1, L2, L3. Check all connections for security. Ensure the input breaker is closed.

Output voltage is unstable or fluctuates

Confirm the AC input voltage is stable and within range. Check for loose connections on the output terminals. Ensure the total load does not exceed the 20A (480W) capacity.

Overload or short circuit protection trips frequently

Check the connected load for faults or short circuits. Ensure the load's power consumption does not exceed the unit's capacity. SFB Technology is designed to trip quickly; investigate the cause of the repeated tripping.

Unit overheats

Ensure adequate ventilation around the unit. Check that the load is not exceeding the maximum output current. Clean any dust or obstructions from the ventilation slots.

Pros and Cons

Pros

  • Highly reliable and stable power output.
  • SFB Technology provides enhanced safety by quickly clearing faults.
  • High efficiency leads to energy savings and less heat.
  • Robust construction suitable for harsh industrial environments.
  • Compact design saves space in control cabinets.

Cons

  • Requires a 3-phase AC input, not suitable for single-phase systems.
  • Higher initial cost compared to basic power supplies.
  • Input voltage range (400-500V AC) may not be universally available.
  • Output voltage is fixed at 24V DC and not adjustable.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the unit onto a standard DIN rail (35mm x 7.5mm or 35mm x 15mm) in a control cabinet. Ensure adequate ventilation space around the unit as per the manufacturer's guidelines.
  2. Wiring: Connect the 3-phase AC input terminals (L1, L2, L3) to the appropriate power source (400-500V AC, 45-65 Hz).
  3. Output Connection: Connect the 24V DC output terminals (+V, -V) to your load. Ensure correct polarity to avoid damage.
  4. Grounding: Connect the ground terminal to a reliable earth ground.

Compatibility:

  • Input: Designed for 3-phase AC input voltage between 320V and 575V AC and frequency between 45Hz and 65Hz. Not compatible with single-phase AC or DC input.
  • Output: Provides a fixed 24V DC output. Ensure your connected devices operate within this voltage range.
  • Environment: Suitable for industrial environments with operating temperatures from -25°C to +70°C.

Care:

  • Cleaning: Periodically clean the unit using a dry, soft cloth. Avoid using solvents or abrasive cleaners. Ensure the unit is de-energized before cleaning.
  • Ventilation: Ensure ventilation slots are kept clear of dust and debris to maintain optimal operating temperature and performance.
  • Inspection: Regularly inspect wiring connections for tightness and signs of wear. Check for any physical damage.
