We have supplied voltage sag compensators to plants in India, where grid quality is a known issue. When the goal is riding through short sags, a compensator is often more economical than a battery UPS because there are no batteries to maintain and replace.
Ride-through time and capacity differ by product. Send the load (kVA), voltage and phases, and any records of dips at the site, and we will propose a suitable unit.
Before you order
If you also need to cover outages of several minutes or more, a UPS or generator is required. We can help compare both options.
