Product Information
Full details
This 3-phase primary-switched power supply unit is designed for industrial applications demanding high system availability and reliability. Its key benefit is ensuring continuous operation even under challenging conditions, such as temporary phase failures or heavy loads, with a notable caveat being its specific input voltage range. The QUINT-PS/3AC/24DC/40 provides 24 VDC output at 40A, featuring SFB Technology for rapid circuit breaker tripping, preventive function monitoring, and a Power Boost for steady starts. It also offers remote monitoring capabilities and adjustable output voltage for battery charging or voltage balancing.

FAQs
What is SFB Technology?
SFB stands for Selective Fuss Breaking. It's a technology that allows the power supply to deliver a surge of current for a short period, enabling standard circuit breakers to trip quickly and selectively without affecting other circuits on the same power rail.
Can this power supply be used with a single-phase input?
No, this specific model (QUINT-PS/3AC/24DC/40) is designed exclusively for 3-phase AC input voltage.
What is the purpose of the 'Power Boost' function?
Power Boost provides a temporary current surge (up to 6 times the nominal current for 12 ms) to reliably start high-power loads like motors or systems with large capacitor banks, preventing nuisance tripping of the power supply.
How do I adjust the output voltage?
The output voltage can be adjusted via a potentiometer located on the unit. Refer to the installation manual for the exact location and procedure.
What is the recommended wire size for connections?
The recommended wire size for the screw terminals is between 18 AWG (minimum) and 10 AWG (maximum).
What does 'preventive function monitoring' do?
This feature monitors critical operating parameters of the power supply and provides an early warning (e.g., via an LED or relay output) before a failure occurs, allowing for planned maintenance.
What is the MTBF (Mean Time Between Failures) for this unit?
The Mean Time Between Failures (MTBF) for the QUINT-PS/3AC/24DC/40 is 880,000 hours, indicating high reliability.
Troubleshooting
Unit does not power on (no output voltage)
Verify that the 3-phase AC input voltage is within the specified range (320-575 V) and correctly wired. Check for loose connections at the input terminals. Ensure the AC input frequency is between 45-65 Hz.
Output voltage is unstable or fluctuating
Check the AC input voltage stability. Ensure the load connected does not exceed the 40A rating. Verify all screw terminals are tightened securely.
SFB technology not tripping circuits as expected
Confirm the load characteristics and tripping requirements are compatible with SFB technology. Ensure the connected circuit breakers are correctly rated.
Power Boost feature does not engage
Verify that the load demands exceed the continuous output rating and that the inrush current is within the expected parameters for Power Boost activation. Ensure the unit is not already operating at its thermal limit.
Remote monitoring relay not activating
Check the wiring of the remote monitoring output. Ensure the unit is in a state that should trigger the relay (e.g., fault condition, operational status). Confirm the relay contacts are not damaged.
Pros and Cons
Pros
- Ensures high system availability with SFB Technology.
- Proactive error detection via preventive function monitoring.
- Reliable startup for high-demand loads with Power Boost.
- Maintains operation during single-phase failures.
- Versatile for battery charging and voltage balancing applications.
Cons
- Requires a 3-phase AC input within a specific voltage range (320-575 V).
- Not suitable for single-phase input applications.
- Higher initial cost compared to basic power supplies.
- Requires careful wiring for optimal performance and safety.
Setup, Compatibility & Care
Setup:
- Mounting: Mount the unit vertically on a standard 35 mm DIN rail (EN 60715).
- Wiring: Connect the 3-phase AC input (L1, L2, L3) and ground. Connect the 24 VDC output terminals (+V, -V). Ensure all connections are secure using the screw terminals.
- AWG Size: Use wire sizes between 18 AWG and 10 AWG for connections.
- Output Adjustment: If required, adjust the output voltage using the designated potentiometer.
- Remote Monitoring: Connect the remote monitoring relay contacts as needed.
Compatibility:
- Input Voltage: Requires a 3-phase AC input between 320 V and 575 V.
- Output Voltage: Provides a nominal 24 VDC, adjustable.
- Mounting: Designed for standard 35 mm DIN rail mounting.
Care:
- Cleaning: Regularly dust the unit with a dry cloth. If necessary, use a slightly damp cloth, ensuring no moisture enters the terminals. Always disconnect power before cleaning.
- Ventilation: Ensure adequate ventilation around the unit. Do not obstruct air vents. The operating ambient temperature range is -25°C to 70°C.
- Inspection: Periodically check wiring connections for tightness and signs of wear.
