⚠️ Key Notes for Replacement

1. If loads include many solenoid valves or capacitive loads requiring high startup inrush current: Prioritize models with Boost + relay alarm: Weidmüller PRO MAX3, PULS ML60.241. Direct replacement with Mean Well DR-60-24 is not recommended.
2. Project specification requires DC‑OK dry contact signal to PLC for power fault diagnosis: Models with relay alarm must be selected; indicator-only versions cannot support remote fault reporting.
3. Low-temperature environments (below -10℃): Exclude OMRON and Mean Well. Select Phoenix / Weidmüller / PULS.
4. Mounting width: Original Phoenix unit width 32mm; some competitors are 40mm wide. Verify DIN rail space for cabinet retrofit.

Powered loads: Medium/small PLC, remote IO modules, proximity sensors, capteurs photoélectriques, voyants lumineux, a small number of solenoid valves.

Selection rationale: Solenoid valves draw high inrush current at power-on. Dynamic Boost 2× short-time current prevents voltage drop and false protection triggering during startup. DC‑OK relay connected to PLC to implement remote power fault alarm.

2. Robot auxiliary control cabinets: Power supply for robot peripheral safety IO, sensor banks and safety relays.
3. Test fixtures / automated test benches: Laboratory and production line jigs. Wide temperature range accommodates large temperature fluctuations on the shop floor; predictive fault monitoring simplifies maintenance.
4. Traitement de l'eau & Ingénierie municipale
5. Small pump station and valve control boxes: Local on-site control cabinets powering RTUs, flow/pressure transmitters, electric valve actuators and signal acquisition modules.

Selection rationale: Severe grid fluctuation on site, wide input voltage + large plage de température. DC‑OK signal uploaded to SCADA for early warning of power supply aging and anomalies.

2. Automatisation des bâtiments (BA), HVAC control cabinets: DDC controllers, temperature/humidity sensors, damper actuators.

Note: If many high-power damper actuators are present, current calculation is required. This 60W power supply is only suitable for small BA control cabinets.

III. Pouvoir & New Energy Auxiliary Control Cabinets

1. Secondary control of switchgear, local acquisition units in combiner boxes: Power monitoring modules, acquisition de température, communication gateways and compact RTUs.

Avantages: SFB selective breaking, short-circuit on one branch will not shut down the entire 24V system. DC‑OK dry contact uploaded to back-end monitoring system, meeting power industry requirements for power status reporting.

Typical load example: Medium-small PLC (15W) + 8-point remote IO + 6~10 sensors + 2~3 24V solenoid valves. Static current approx.1.8A, startup peak current up to 4~5A, which perfectly matches the Dynamic Boost capability of this power supply.

✅ Convient / Unsuitable Scenarios Quick Reference

✅ Recommended Application

Loads contain solenoid valves or capacitive loads with high power-on inrush current

Power fault signal (DC‑OK dry contact) needs to be sent to upper PLC/SCADA for remote monitoring

Large cabinet temperature variation, ambient temperature can drop below -10℃ in winter

Process requirement: short-circuit on one branch must not cause total 24V power loss (SFB selective fuse breaking)

Project requires high-reliability industrial power supply with CE/UL/EAC certifications

❌ Non recommandé

Continuous static load current permanently higher than 2.2A (insufficient margin)

Large quantity of high-power solenoid valves and high-current actuators with sustained peak load

Non-enclosed cabinets with heavy moisture and corrosive atmosphere (coated version required)

Total 24V load power significantly exceeding 60W; higher-rated QUINT4 power supply shall be selected.

✅ Matching Expansion Options (Same Cabinet Layout)

1. Alimentation redondante: Pair with Phoenix redundant module, two 2904598 units for redundancy to improve availability;
2. Backup power: Match with QUINT4 DC-UPS module to maintain power briefly during mains dropout, protecting PLC and communication data.
