| Número de pedido. | Aporte | 24V Output | Fuerza | Posicionamiento |
| 6EP1436-2BA10 | 3AC 400–500V | 20A | 480W. | Medium-capacity 3-phase power supply |
| 6EP1437-2BA10 | 3AC 400–500V | 40A | 960W. | High-power standard 3-phase power supply |
| 6EP1437-3BA00 | 3AC 400–500V | 40A | 960W. | Equipped with relay signal output (fault contacts 13/14) |
- Definición de terminal
- Terminales de entrada: L1, L2, L3, educación física (3 fases + protective earth)
- Output terminals: Dual sets of +24V, 0V (parallel for current sharing)
- Voltage trimming potentiometer: Located at bottom; adjust with flat screwdriver
- Luz indicadora: Solid green = normal output; apagado / flashing = fault (pérdida de fase, cortocircuito, calentamiento excesivo)
- Escenarios de aplicación típicos
- Large PLC control cabinets (S7-1500/400, full-station power supply for ET200SP distributed I/O)
- Multi-axis servo systems, inverter control stations, robot workstations
- Embalaje, logistics sorting, automotive welding & assembly production lines
- Tratamiento de agua, energía eólica, metalurgia, cement and other high-power industrial control equipment
- Centralized 24V power supply scenarios requiring 3-phase industrial incoming power and high current loads
VII. Reemplazo & Capacity Expansion Solutions
- Upgraded same-spec model: 6EP1437-3BA00 (with fault relay contacts for PLC diagnostic connection)
- Capacity expansion: Parallel two 6EP1437-2BA10 units for max. 80A / 1920W output
- Downsized alternative: 6EP1436-2BA10 (20A / 480W.) for half-load applications
VIII. Prohibiciones de instalación & Guía de solución de problemas
Forbidden Operations (Critical Restrictions)
- Horizontal or upside-down mounting is strictly prohibited; blocked cooling air duct triggers rapid over-temperature protection
- Long-term power-on with direct output short circuit will cause continuous hiccup power derating
- Long-term operation with missing input phase accelerates aging of internal power components
- Do not install alongside high-power inverters without partition plates to avoid EMC interference
Common Fault Matrix
| Fenómeno | Causa principal | Contramedidas |
| Green light off, no 24V output | 3-phase power loss, disyuntor disparado, internal overheating | Check 3-phase incoming voltage; power off and cool down then restart; clean dust in air duct |
| Green light flashing, output voltage drop | Output overload / cortocircuito | Disconnect loads and locate short circuit by segmentation; limit total load within 40A |
| Output voltage below 23V under load | Undersized cables causing excessive voltage drop | Thicken 24V main cables; add auxiliary power supplies nearby |
| Frequent over-temperature shutdown | Ambient temp ＞55℃, clogged air duct, fully enclosed cabinet | Install cabinet cooling fan, lower ambient temperature, reserve ≥50mm top & bottom ventilation clearance |

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