What to do if the Vertiv Tech Power Supply DC voltage is low?
- LlisaperezAug 19, 2025
If the DC voltage is low, first check if it's due to a mains failure; if so, disconnect some loads to extend system operation. Next, verify the DC under-voltage value set in the controller and correct it if needed. Also, check for inoperative rectifiers or ones with no output current, and replace them if found. Finally, ensure the total rectifier current exceeds the total load current during float charge; if not, reduce loads or add rectifiers so the rectifier current is at least 120% of the load current with one redundant rectifier.
