What to do if Evoqua Controller indicates input under-voltage?
- Bblake74Jul 31, 2025
If the AC input voltage to your Evoqua Controller G2 drops below 726 V, the DC power stage will restart. However, if this happens three times within 30 minutes, the DC power stage will shut down. To restart it, you'll need to manually cycle the AC input power to the controller off and then on again.
