The SITOP modular power supply is a primary-clocked, stabilized DC power supply for 1-phase/2-phase AC line supplies. It features wide-range input, adjustable output voltage (24-28.8 V), and a power boost function. The device offers selectable short-circuit response (constant current or latching shutdown) and can be expanded with supplementary modules for increased system availability. It displays operating status via 3 LEDs. Installation typically involves mounting on standard mounting rails in a control cabinet.
Troubleshooting and error codes
| Problem | Possible Cause | Remedy |
|---|---|---|
| No output voltage | No line voltage. | Check line voltage supply. |
| Output voltage too low | Output voltage not set correctly. | Adjust output voltage using potentiometer. |
| Output voltage too high | Output voltage not set correctly. | Adjust output voltage using potentiometer. |
| Output voltage fluctuates | Output voltage set incorrectly or load too high. | Check output voltage setting and load. |
| Device overheats | Overload or insufficient ventilation. | Reduce load or improve ventilation. |
| LEDs do not light up | No power supply. | Check line voltage supply. |
