Preliminary Solution Proposal For Data Center-MumbaiModular Redundant Scalable UPS By Gamatronic

Feb 2013

• Data Center Environment: Critical IT loads.• Configuration: Tier IV, 2N+1 distributed

redundancy. • Initial Capacity: 200KVA.• Ultimate Capacity, at later-stage: 400KVA.• Preferred by the user to upgrade/add capacity

without load-shutdown.

Requirement

Proposal A: Mega Power+

• Mega Power+ Modular Redundant Scalable UPS• Initial Capacity: 200KVA/KW N+1 = 225KVA/KW, total 9 power

modules each 25KVA/25KW. • Ultimate Capacity: 475KVA/KW N+1= 500KVA/KW, total 20 power

modules each 25KVA/25KW. • Hot-swap power modules, hot-swap interface controller.• Distributed redundant control architecture.• No load shutdown required to upgrade capacity. • The upstream infrastructure need to be prepared for the ultimate

final power capacity. • It is possible to replace/add battery banks without to shutdown the

system. The connection circuitry of the battery banks to the UPS need to be prepared accordingly.

Proposal B: Parallel Power+

• Power+ Modular Redundant Scalable UPS, 3 units 80KVA in parallel • Initial Capacity: 3X80KVA= 240KVA= 210KVA N+3. (210KVA/168KW).

Total 24 power modules each 10KVA/8KW.• Ultimate Capacity: 5X100KVA= 500KVA= 450KVA N+5. (450KVA/360KW) .

Total 50 power modules each 10KVA/8KW.• Hot-swap power modules, hot-swap interface controller.• Distributed redundant control architecture.• The upstream infrastructure need to be prepared for the ultimate final

power capacity (of each single UPS) • It is recommended to shutdown the system when adding additional UPS

unit. • No need to take a shutdown when adding 10KVA/8KW power modules. • Each Power+ unit has its own separate battery bank.

Proposal C: Conventional Solution

• Conventional 2X200KVA=400KVA=200KVA N+1 in parallel. • Initial Capacity: 2X200KVA= 400KVA= 200KVA N+1. • Ultimate Capacity: 3X200KVA= 600KVA= 400KVA N+1. • It is recommended to shutdown the system when adding

additional UPS unit.
