🛠️ Common Troubleshooting

1. No green LED: Check AC input voltage, 内部ヒューズが切れた; Output short-circuit protection latch, power cycle to reset
2. Voltage drop under load: Low input voltage, overtemperature derating, continuous load exceeding 120% rating
3. Alarm relay not closed: Power supply under protection state or output voltage too low

✅ Typical Load Combination Reference (5A Capacity)

S7-1200 CPU + 8~16 DI/DO points + HMI + several proximity/photoelectric sensors + 2~4 pcs 24V solenoid valves + 安全リレー.

注意: Solenoid valve has high inrush current, reserve margin during selection; High-power valves require separate power loop.

⚠️ Not Recommended Applications

1. High-power 24V motors, heavy heating loads (This is control power supply, not power supply for high power loads)
2. 3-phase input system (unless single-phase power is tapped from front end)
3. Heavy corrosion environment, direct outdoor exposure (must be installed inside control cabinet)
4. Direct installation in hazardous explosive area
5. Main power supply for large systems (10A+ model or redundant scheme recommended)

✅ Selection Key Points

利点: Power-good relay output, 150% short-time overload capacity, compact DIN rail mounting, SELV safety isolation, ideal for small control cabinets requiring power status monitoring.

Capacity expansion: Multiple units in parallel to increase total output current; Reduce maximum ambient temperature when paralleling.
