Phoenix Contact QUINT-PS/3AC/24DC/40 Three-Phase 24VDC/40A Industrial Power Supply – QUINT Power Series
When a critical 24 VDC bus collapses on the factory floor, every second of unplanned downtime translates directly into scrapped batches, missed SLAs, and emergency maintenance costs that dwarf the price of the power supply itself. Conveyor lines freeze, safety PLCs lose their keep-alive signal, and SCADA screens go dark — all because a single power supply failed to deliver. The Phoenix Contact QUINT-PS/3AC/24DC/40 was engineered precisely to prevent that scenario, delivering a rock-solid 40 A of regulated 24 VDC from a three-phase AC input with the redundancy intelligence and diagnostic depth that mission-critical installations demand.
Within the QUINT Power Series — Phoenix Contact’s flagship line for demanding industrial environments — the QUINT-PS/3AC/24DC/40 occupies the high-current, three-phase tier. It is the go-to choice for large control cabinets, heavy-duty process skids, and multi-axis servo systems where single-phase supplies simply cannot provide the current density or the phase-balanced loading that grid operators and plant engineers require. Globally, the QUINT Power Series is recognized as a benchmark for DIN-rail power supplies, trusted by system integrators across automotive, oil & gas, water treatment, and semiconductor manufacturing.

Frequently Asked Questions
- Q: Is the QUINT-PS/3AC/24DC/40 suitable for single-phase input?
- A: No. This model is designed exclusively for three-phase AC input (3 × 400/500 VAC). For single-phase applications, please refer to the QUINT-PS/1AC/24DC series.
- Q: Can I connect two units in parallel for 80 A output?
- A: Yes, with the appropriate QUINT-ORING decoupling module to prevent reverse current flow. Contact us for the recommended redundancy configuration.
- Q: What does SFB technology mean in practice?
- A: SFB (Selective Fuse Breaking) allows the power supply to deliver up to 200 % of rated current for a short burst, enabling downstream branch fuses to blow selectively — isolating only the faulted circuit while keeping all other loads powered.
- Q: Is this unit ATEX certified for hazardous areas?
- A: The QUINT-PS/3AC/24DC/40 carries ATEX Zone 2 approval, making it suitable for installation in areas where explosive atmospheres may occasionally be present. Always verify the full ATEX certificate for your specific installation requirements.
