Phoenix Contact 2904603 Industrial DIN Rail Switching Power Supply

Full Model: QUINT4-PS/1AC/24DC/40

✅ Basic Specifications

Order No.: 2904603

Series: QUINT4 (4th-generation QUINT POWER high-end power supply)

Input: Single-phase 100…240 V AC

Output: 24 V DC, 40 A, rated power 960 W

Mounting: DIN 35 mm rail mounting

Key Features: SFB Selective Fuse Breaking, NFC parameter configuration, free characteristic curve, wide temperature operation, pre-warning signal output

✅ Core Advantages

1. SFB Selective Fuse Breaking: Only the downstream protection trips in case of branch short-circuit; the main power supply remains online without lockout, widely used in automated production lines.
2. NFC Interface: Read parameters, adjust voltage, set alarm thresholds and export reports directly via mobile APP.
3. Parallel redundancy supported, suitable for high-power control cabinets, PLC clusters and servo power supply.
4. Zero-clearance side-by-side installation; no extra heat dissipation gap required.

✅ Cross-References & Replacements

Previous generation: QUINT-PS/1AC/24DC/40 (Order No. 2866789, discontinued); 2904603 is the direct upgraded replacement.

Lower-power models in the same series: 2904597, 2904598, 2904599, 2904600, 2904601, 2904602.

1. Core Datasheet (English Version)

Order No.: 2904603 | Series: QUINT4 high-end power supply with SFB | Single-phase input, 24 V 40 A, 960 W

Input Ratings

AC voltage: 100~240 V AC (-15% ~ +10% tolerance), stable operation from 85~264 V AC

DC input compatible: 90~300 V DC (≤250 V DC per UL standard)

Frequency range: 45~65 Hz

Built-in slow-blow input fuse: 20 A

Terminals: L / N / PE, screw terminals; stripping length 7 mm, max conductor cross-section 6 mm²

Output Ratings (SFB & BOOST are core functions)

Nominal: 24 V DC, 40 A; adjustable voltage range 18~29.5 V

Static Boost: 45 A continuous (-25℃ ~ 40℃)

Dynamic Boost: 60 A for 5 seconds, to handle servo inrush current

SFB Selective Fuse Breaking peak: 215 A / 12~15 ms

Core function: Downstream branch short-circuit only trips the downstream circuit breaker, main power supply keeps running without shutdown

Residual ripple: < 50 mVpp

OVP overvoltage protection: approx. 32 V DC

Supports parallel redundancy and series voltage boosting; multi-unit current sharing. Recommended with QUINT-ORING redundancy module.

Output terminals: DC+, DC(screw type); max conductor cross-section 16 mm², stripping length 10 mm

Signal Terminals (Push-in spring terminals)

1. DC OK: Passive relay contact 13/14, closed normally; opens when Uout < 0.9×24 V for PLC fault alarm.
2. I＜IN (load pre-warning): Triggers when load current drops below the set threshold; threshold editable via NFC.
3. REM remote enable: Short REM to SGnd = power ON; open circuit = sleep mode (output OFF).
4. NFC: Phoenix QUINT POWER APP; read voltage, current and fault logs, adjust BOOST/SFB curves and export reports.
5. Other Single-Phase 1AC Models (SC Screw Terminals)

12 V DC Output

5 V DC Output

48 V DC Output

Dual Output 2×15 V

III. Single-Phase 1AC | PT Push-In Spring Terminals (Screw-Free, same power, Order No. starting with 2909575)

1. 3-Phase 3AC Input | 24 V Models (High-power 3-phase version with identical QUINT4 SFB technology)

1. Common Series Features (All models)
2. All units equipped with SFB Selective Fuse Breaking + Dynamic Boost + NFC mobile configuration.
3. SC = screw terminal; PT = Push-in spring terminal.
4. Zero-clearance side-by-side mounting, parallel redundancy, DC OK dry contact alarm, REM remote ON/OFF supported.
5. Direct replacement for legacy QUINT-PS series (Order No. 2866xxx); pin assignment fully compatible, plug-and-play.
6. Short Purchasing List (Only 24 V single-phase screw terminal models)
