⚠️ Selection & Replacement Notes

1. Model distinction: 2903154 is 3-phase 3AC; single-phase 1AC version is 2903149, do not mix them up
2. Domestic alternative: Mean Well SDR-240-24, Delta DRP-240-24 (note: no dynamic boost capability for inrush current)
3. Redundancy solution: When paralleling two 2903154 units, use redundancy module such as QUINT-DIODE
4. Installation: Maintain ≥50mm vertical clearance at top and bottom for heat dissipation; units can be mounted side-by-side with zero horizontal clearance

🛠️ Troubleshooting Guide

POWER LED off: Check 3-phase L1/L2/L3 mains supply; loss of any phase may prevent startup; verify PE earth connection

Output voltage drop / insufficient load capacity: Prioritize checking loose terminals, low input voltage and high-temperature derating

OK contact open: Output overcurrent / short circuit or internal overtemperature protection. Disconnect load and retest

Tripping on power-up due to inrush: Utilize boost feature and evaluate switching surge current

📦 HS Code for Export

8504401400 (Static converters, industrial switching power supply, for customs reference only, subject to local customs determination)

TRIO-PS-2G/3AC/24DC/10 (Order No. 2903154)

Efficiency: >92%

Test condition: 400V AC input, full rated load

Additional Power Consumption Parameters

No-load power consumption: ＜1.1 W

Power loss at rated load: ＜22 W

Note: This value is the nominal figure from Phoenix Contact official datasheet. Actual efficiency under light load (20%~50% load) will be slightly lower than the 92% full-load rating.

✅ Key Selection Guidelines

1. Suffix C2LPS: Only available for the 3A single-phase variant with SIL capability; not required for standard automation projects
2. 3AC three-phase models can run on two phases (L1/L2 only)
3. Width reference: 3A=30mm; 5A=36mm; 10A=42mm; 20A=65mm; 40A=120mm, cabinet layout mainly depends on width
