1. Comparison Table of Same-Series 3-Phase Power Supplies

1. Définition du terminal
2. Input terminals: L1, L2, L3, PE (3 étapes + protective earth)
3. Output terminals: Dual sets of +24V, 0V (parallel for current sharing)
4. Voltage trimming potentiometer: Located at bottom; adjust with flat screwdriver
5. Voyant lumineux: Solid green = normal output; désactivé / flashing = fault (perte de phase, court-circuit, surchauffe)
6. Scénarios d'application typiques
7. Large PLC control cabinets (S7-1500/400, full-station power supply for ET200SP distributed I/O)
8. Multi-axis servo systems, inverter control stations, postes de travail robotisés
9. Conditionnement, logistics sorting, automotive welding & assembly production lines
10. Traitement de l'eau, énergie éolienne, métallurgie, cement and other high-power industrial control equipment
11. Centralized 24V power supply scenarios requiring 3-phase industrial incoming power and high current loads

VII. Remplacement & Capacity Expansion Solutions

1. Upgraded same-spec model: 6EP1437-3BA00 (with fault relay contacts for PLC diagnostic connection)
2. Capacity expansion: Parallel two 6EP1437-2BA10 units for max. 80UN / 1920W output
3. Downsized alternative: 6EP1436-2BA10 (20UN / 480W) for half-load applications

VIII. Installation Prohibitions & Guide de dépannage

Forbidden Operations (Critical Restrictions)

1. Horizontal or upside-down mounting is strictly prohibited; blocked cooling air duct triggers rapid over-temperature protection
2. Long-term power-on with direct output short circuit will cause continuous hiccup power derating
3. Long-term operation with missing input phase accelerates aging of internal power components
4. Do not install alongside high-power inverters without partition plates to avoid EMC interference

2. Dimension Differentiation of Confusable Same-Series Models (Avoid Errors in Procurement & Cabinet Layout)

3. Cabinet Installation Clearance Requirements
4. Mounting rail: Standard 35mm TH35 DIN rail, installation verticale (terminals downward)
5. Haut & bottom ventilation clearance: Reserve at least 40mm for heat dissipation; derating mandatory if ambient temp exceeds 55℃
6. Side-by-side mounting: Units of same model can be tightly arranged without extra spacing

Note complémentaire

Dimensions such as 250×180×92 and 145×145×150 shown on some foreign websites belong to the new PSU300S model 6EP1437-2BA20, which is incompatible with the legacy 6EP1437-2BA10. Cabinet cutout and DIN rail layout cannot be shared between them.
