7 UPS

Expandability to 250 KVA

Due to limited space in UPS room, We foresee a challenge in adding batteries to 100KW UPS in the UPS Room in future when modules are added and hence, we suggest considering no expansion for future. In case u select 125 KW as base chassis today, this can be future expandable to 250KW by adding 1 x 125 KW chassis in parallel load sharing.

Follow solicitation specifications

8 Redundancy Module within same chassis

We understand that you have asked for a 100KW UPS but there is no mention of an additional redundant Module above 100KW. Wherever a customer buys single chassis solution, they always buy 1 Additional Module within the same chassis to meet the redundancy requirement also. We request you to clarify if we have to consider 1 extra module above 100KW or not. EX: 4 x 25KW +1 x 25 KW - Total 125

KW.

No-we need 100kW UPS Only having capability to add modules which can go up to 250kW for future expansions.
