Why Engineers Specify This Model
- SFB (Selective Fuse Breaking) Technology – Delivers up to 200 % rated current for 5 seconds, ensuring downstream MCBs trip selectively without nuisance shutdowns of the entire 24 V bus.
- Preventive Maintenance Signaling – The integrated changeover (CO) relay output signals impending output voltage drop to a PLC or SCADA before a fault occurs, enabling planned maintenance instead of emergency shutdowns.
- Wide-Range AC Input – Accepts 85–264 VAC globally; no tap switching required for international machine exports.
- Parallel Redundancy Ready – Two units can be paralleled with QUINT-DIODE/40AC/2X20/1X40 for N+1 redundancy without external OR-ing diodes.
- Compact 45 mm Width – Saves panel real estate versus comparable 10 A supplies; fits standard 24-module DIN rail enclosures.
- Extended Temperature Range – Rated to −25 °C, suitable for outdoor enclosures and cold-storage automation.

Application-Specific FAQ
Q: Can this supply power a Siemens S7-1500 PLC with 8 × SM modules?
A: Yes. A fully loaded S7-1515 with 8 signal modules typically draws 4–6 A at 24 VDC. The QUINT 10 A provides ample headroom and SFB protection for branch MCBs.
Q: What is the difference between QUINT-PS/1AC/24DC/10 and QUINT-PS/1AC/24DC/10/CO?
A: The /CO suffix adds a floating changeover relay output for remote fault signaling to a PLC digital input or SCADA alarm card. The base electrical performance is identical.
Q: Can two units be paralleled for 20 A output?
A: Yes, using the QUINT-DIODE/40AC/2X20/1X40 OR-ing module. This also provides N+1 redundancy; if one PSU fails, the second carries the full 10 A load without interruption.
Q: Is this unit suitable for 110 VAC North American panels?
A: Yes. The wide-range input (85–264 VAC) accepts 110/120 VAC without any configuration change.
Q: What is the warranty?
A: Konmask.com provides a 12-month functional warranty. PHOENIX CONTACT factory warranty terms apply to new-in-box units.
