The SIMATIC ET200SP PS is a regulated system power supply for automated systems. It features a 1-phase 120/230 V AC input with automatic switchover, adjustable output voltage (22.8 - 28 V), and overload capability. It includes an integrated signaling contact for "24 V O.K." and operates within an ambient temperature range of -30 to 70 °C. Key functions include electronic current limiting, overload protection, and the ability to be connected in parallel for increased power or in series for increased voltage. It also supports buffering of brief power failures and longer power outages through various SITOP DC-UPS solutions.
Troubleshooting and error codes
| Problem | Possible Cause | Remedy |
|---|---|---|
| No output voltage | No input voltage | Check input voltage. |
| Output voltage too low | Output voltage not set | Set output voltage using potentiometer. |
| Output voltage too low | Overload | Reduce load. Check for short circuits. |
| Output voltage too low | Input voltage too low | Check input voltage. |
| Device overheating | Ambient temperature too high | Ensure sufficient ventilation. Reduce load. |
| Device overheating | Load too high | Reduce load. |
| Signaling contact not active | Device not OK (e.g. overload, missing input voltage) | Check device status via LED. Troubleshoot the cause. |
