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.


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

Why Piller UNIBLOCK UBTD




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 !

?

Ishort circuit from the mains

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
