Preliminary Solution Proposal For Data Center-Mumbai Modular 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. Description

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. Description

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. Description
