in the Philippines has ordered 4 250kVA Series MC Hybrid Rotary UPS
systems for their critical data center in Manila. The UPS systems are configured in two (N+1) redundant configurations. Metropolitan Bank and Trust Company
(Metrobank) is one of the two largest private commercial/universal banks in the Philippines. It has a very large data communications network that covers more than 200 branches spread throughout the various islands.
Metrobank decided to purchase a PS&C Series MC UPS system
after experiencing a major disaster last December
when business was at its peak due to the approaching Christmas holidays. At the height of its online operation on December 22nd, the utility power failed and a 150kVA
static UPS supporting the mainframe, and another 150kVA static UPS on standby, both failed. The entire database was lost. The UPS systems were repaired within a day; however, it took three days to restore the database. Before the disaster Metrobank had some concern about the Rotary (Motor Generator) Topology, but after the disaster they understood the importance of having the greatest MTBF possible.
