🛠️ Wiring Notes

1. مدخل: 3-phase L1/L2/L3 + PE protective earth. The unit can still operate with phase loss, but DC OK signal will trigger an alarm.
2. الإخراج: DC+ / DC-. Direct parallel connection with automatic current sharing, no extra current sharing wire required. For redundant systems, a decoupling diode module is recommended.
3. DC OK: Passive relay contact. Closed when power supply healthy; opens upon power loss, fault or overtemperature, connected to PLC for fault diagnosis.

🔄 Upgrade & استبدال

1. 2الجيل الثاني: TRIO-PS-2G/3AC/24DC/20 (2903155, النموذج الحالي)
2. 3rd generation upgrade: TRIO3-PS/3AC/24DC/20 (2186227). Pin-out and mounting dimensions fully compatible, improved EMC and reliability, direct drop-in replacement.

⚠️ Common Troubleshooting

1. DC OK indicator off, لا يوجد مخرج

Check for missing phase, loose wiring or tripped upstream circuit breaker

Overtemperature protection activated: Check cabinet ventilation and ambient temperature

2. Normal voltage at no-load, voltage drop under load

Verify reliable Push-in connection of output terminals; insufficient output cable cross-section

Confirm load does not continuously exceed 20A (Boost only lasts 5 ثواني, cannot sustain 30A continuously)

3. Protection trips immediately after power-up

Short circuit or ground fault on DC output side; isolate load and test power supply at no-load

📌 Application

Machine tool automation, packaging lines, metallurgy auxiliary control, large control cabinets, centralized power supply for PLC, valve islands, sensors and 24V solenoid valve banks. Boost function ideal for heavy inrush loads.

Comparison List of Domestic Replacements for TRIO-PS-2G/3AC/24DC/20 (2903155)

Key characteristics of original unit: 3-phase 3×400~500VAC input, 24V 20A/480W, 150% short-time Boost (30A/5s), DC OK relay alarm, جبل السكك الحديدية DIN, parallel redundancy support, adjustable 24~28V output, IP20, -25~70 درجة مئوية.

ملحوظة: Meanwell is Taiwanese owned domestic brand; Inovance and Great Wall are mainland manufacturers. Meanwell TDR-480-24 is the preferred closest alternative.

📌 Key Selection Notes

1. Boost is critical: Original Phoenix delivers 30A for 5 seconds for solenoid banks and motor startup. Chuanglian CL-3AC480-24 has insufficient peak current, not allowed for inrush loads.
2. Terminal difference: Original Push-in tool-free; Meanwell TDR uses screw terminals requiring wiring modification; Inovance/Great Wall support optional Push-in terminals for minimal cabinet changes.
3. Parallel redundancy:

فينيكس: Direct parallel of identical units with automatic current sharing

Inovance/Great Wall: Dedicated current sharing cable for better parallel performance

Meanwell TDR: Parallel possible, DR-RDN20 decoupling diode module recommended for fault isolation

4. Temperature derating: Original starts derating >60درجه مئوية; ابتكار & Great Wall have similar curve; Meanwell TDR requires derating at full load near 70℃
5. إي إم سي: Phoenix EN61000-6-2 industrial immunity; Meanwell TDR and Inovance meet same EMC class, no extra filter required inside cabinet.

⚠️ Not Recommended Models

Single-phase power supplies (NDR/DR series): 220V single-phase input, cannot replace 3AC 3-phase models

Generic domestic 3-phase power supplies without DC OK relay: Only LED indicator, no PLC fault alarm, not suitable for automation equipment.

📋 Modification Effort Assessment

1. Minimal change: Inovance MD800-PS-3AC400-2420 (Push-in optional, similar dimension, matched parameters)
2. Standard replacement: Meanwell TDR-480-24 (good stock, widely verified; only change from Push-in to screw terminals)
3. Low-cost batch cabinet: Great Wall DR960S 3-phase variant for domestic system integration projects
