UNIBLOCK-T Diesel

UNIBLOCK-T Diesel is an innovative approach to cost effective and efficient power protection, ideal for an expanded range of commercial, critical process, industrial, and power quality applications. At the heart of the UNIBLOCK-T Diesel is a unique flywheel energy storage module that eliminates the need for batteries. The UNIBLOCK-T Diesel design maximises the benefits of flywheel energy storage and incorporates an integrated diesel engine to create an extremely reliable, fault tolerant, and compact online UPS system that deli-vers outstanding performance without the cost, space, maintenance, and operational problems of batteries.

A New Era of UPS Protection
Kinetic Energy Store - (POWERBRIGDGE)

Infrequent starts due to long ride through times
From 12 seconds of power outage ride--through at 1670 kVA to 2 minutes at 150 kVA, without the engine
Non-stressful engine operation, sufficient time to start, no prelubrication etc.
No nuisance engines starts, POWERBRIDCE rides through more than 97% of all power disturbances
Recharges in 2 minutes or less, protects critical load from repetitive power inter-ruptions

Isolates and Eliminates Harmonics
Blocks load harmonics from reaching the mains
Isolates the load from harmful input har-monics

Corrects Power Factor
Isolates poor power factor loads from the utility
Input power factor exceeds 95% at full load
Eliminates the need for power factor correction capacitors
Reduces power factor related energy costs

Reliable Ride-Through
Ensures continuous power for any outage duration
Eliminates downtime caused by lightning hits, utility re-closer operations, capacitor switching, storms and other common cau-ses of power disruption

Greater Power Quality Improvement
Corrects low voltage, including sags to 50% of nominal
Protects against brownouts (-30%) with-out using stored energy
Handles 100% non-linear loads
Exceptional step load response
Absorbs reverse power flow
Stable output frequency during engine operation including 100% load changes

High Efficiency
Up to 96%

Better System Co-ordination
Fault clearing capacity of more than 14 x full load current for 10ms, and 3 x full load for 5 seconds
Allows upstream fault clearing without disconnecting the input
Excellent frequency stability on Diesel operation

System Reliability
Capacitor free design eliminates the highest failure components
Low stress naturally commutated converter
Durable rotary technology is less sensitive to overloads and electrical disturbances
Design life greater than 25 years
Separate paralleling controls in each module eliminate single point failures
Simple mechanical system, no brushes
Seamless, low stress power transfer to and from the engine
Eliminates integration problems between the UPS and engine generator
Risk free engine testing, peak shaving and utility load reduction
Eliminates the need for transfer switches
