DEAR SIRS,

We are Looking for COST-EFFECTIVE, 3-PHASE, 200-kVA, UPS Solution combining:

ONLINE/DOUBLE-CONVERSION and DESIGN FOR HEAVY INDUCTIVE LOADS

APPLICATION:
AVOIDING BIG WATER PUMPS 3-PHASE MOTORS ( Typically 150HP @440VAC ) TO STOP DURING MOMENTARY GRID FAILURES ( FROM FEW SECONDS TO FEW MINUTES )

As short as five (5) Minutes back-up time could solve 90% of the stopping issues.

TO REDUCE EXPENSIVE SHIPPING COST:
1. -BATTERIES: SHOULD BE EXTERNALLY INSTALLED, COMMERCIALLY AVAILABLE AGM, LiFePO4, OR Li-ion
2. -ISOLATION TRANSFORMER: WHENEVER FEASIBLE, WE PREFER TO BUY AND INSTALL LOCALLY.

THANK YOU IN ADVANCE FOR ANY SUGGESTIONS AND QUOTES.
