Phoenix Contact 2866750 QUINT-PS/1AC/24DC/5 – 24 V DC, 5 A Power Supply
The Phoenix Contact 2866750 (QUINT-PS/1AC/24DC/5) is a compact, single-phase, primary-switched DIN rail power supply from the Phoenix Contact QUINT POWER range. It delivers 24 V DC at 5 A (120 W) in a housing only 40 mm wide, and the output can be adjusted from 18 to 29.5 V DC. Its POWER BOOST reserve supplies 7.5 A permanently for starting loads with high inrush current. Its SFB technology (Selective Fuse Breaking) supplies 30 A for 12 ms, so standard miniature circuit breakers trip selectively and only the faulty circuit is switched off.
What the Part Number Means
- 2866750 – Phoenix Contact order number
- QUINT-PS – QUINT POWER power supply
- 1AC – Single-phase AC input
- 24DC – 24 V DC output
- 5 – 5 A nominal output current
Key Features
- SFB technology: 30 A for 12 ms to trip circuit breakers selectively
- POWER BOOST: 7.5 A permanently (up to +40 °C), for loads with high start-up current
- Preventive function monitoring: active DC OK and POWER BOOST signal outputs, a floating DC OK relay contact and status LEDs
- Long mains buffering: over 55 ms, so short supply dips do not interrupt the 24 V output
- Compact: 40 mm wide, ideal for small control panels
