UNIBLOCK UBTD Containerized Version
Advantages:Operating readiness immediately on connecting to the mains. No structural measures for noise attenuation, ventilation or cabling.No expenditure for on-site testing and commissioning.No outlay on complex installation or plant room construction.Temporary use in different locations.Reduced on site programme.
A Langley Holdings Company
Application: Parallel redundant configuration(Tier II)
Load evenly spread between UPS modules
Maintenance of UPS possible without switching to bypass
Disconnector for separation of UPS bus bar
Optional external automatic bypass and external bypass control
Distribution paths upstream and downstream still single-points-of-failure
Number of parallel connected UPS limited by short circuit current capability of UPS bus bar

What makes the difference?
3-times rated current does not allow a safe & fast clearing of downstream faults. Consequence during mains failure:UPS output voltage = 0 , all loads affected !

14-times high short circuitcurrent for a quick switch-offof defective loads during all operation modes, mains, battery and Diesel.
14-times rated Current ensures that faulty load is disconnected in 10ms
