Remarks

UPS RATING :60KVA (3 x 20KVA)
Type: Rack mounted UPS
UPS shall utilize rack mounted redundant scalable array architecture
UPS system shall power train shall be comprised of hot swappable/ user replaceable 20KVA power modules, which shall operate in parallel.
Each 20kVA power module contains a full rated input rectifier / boost converter, full rated output inverter, and battery charging circuit.
The system shall also comprise of a user-replaceable continuous duty hot swappable bypass static switch module, hot swappable / user replaceable battery modules, redundant control modules, redundant logic power supplies, and LCD interface display.
All of the above system components shall be housed in a standard 600mm wide, 1070mm deep, and 1991mm high equipment rack (tentative measurements).
The UPS shall be designed to permit ready access to modules and assemblies. The placement of parts, test points and terminals shall be such that they are accessible for circuit checking, adjustment and maintenance without removal of any adjustment module or assembly.
All power semiconductors in the module shall be protected by fast acting fuses so that failure of any one power semiconductor will not cause cascading failures.
Each fuse shall preferably be provided with a blown fuse indicator on the control panel. The UPS module shall not incur permanent damage to itself and the connected load under all predictable types of failure conditions within itself and the connected load.
UPS shall be designed to interface and operate with DG set to maintain UPS supply in case of utility supply failure without any distortion on DG supply or hunting or de-rating DG set.
Qty : 2 sets
(each set consist of UPS unit and battery bank )
Tenderers shall supply the department approved make items only. The approved makes for Modular UPS are: Emerson, Socomec, Riello AROS, APC (Schneider), Numeric.
