Hipulse-ETM is a solutionof that Europen initiative of Liebert,which offers you the best-in-classvalue.
Liebert Hipulse-ETM500kVA - 800kVAAC Power for Business-Critical ContinuityValue-Added FeaturesHaving thoroughly understood &captured the present, latest &anticipated customer needs across theworld, the Product Management Teamof Liebert Hiross has come out with thefollowing value-added features for yourhyper critical applications.Utility-Friendly & Generator-FriendlyLiebert Hipulse-ETM with its 12-pulserectifier version, considering in-builtoptional harmonic filter, is extremelyutility-friendly. In this configuration,Hipulse E achieves 4-5% input currentTHD (Total Harmonic Distortion) and 0.90 input power factor (PF). Theformer one (the THD) ensures almostclean power in the upstream avoidingpollution and thus damage to the othersemi-critical loads connected to theupstream power distribution bus.Moreover, it also ensures lowerinvestments in cable costs (due toreduced cable size).The later one (the PF) helps youmaximising active power leading tosaving in cost of ownership (in terms oflesser electricity bill) and also ensuresreduced investment towards motorgenerator set (by way of minimising itssizing), making it generator-friendly.Overall, Hipulse-ETM is an UtilityFriendly & Generator-Friendly systememploying this appropriate solution.Horizontal Xpandability &RedundancyLiebert Hipulse-ETM is designed toparallel up to as high as six (6) UPSmodules to achieve either capacity orredundancy. The system can grow(through horizontal xpandability) asyour business grows or the system canprovide you higher availability, as yourbusiness demands it. Achievingparallelibility up to six modules can beachieved with or without thecentralized static switch & centralizedcontroller. Thanks to Liebert’sunmatched paralleling techniqueto provide you with both thealternatives aptly needed for largepower UPS configurations.Multi Bus CompatibilityLiebert Hipulse-ETM has the feature ofachieving multi bus configurations bythe use of optional HiSync (to ensuresynchronisation among the multi bussystems) and optional HiSwitch orLiebert HiSwitch2 (the static transferswitches).This configuration will allow you toautomatically transfer power (from onebus to the other, whenever the needarises). This gives you significantvalues to ensure high availability(Hi 9’s) of quality power.We have successfully executedmultiple projects of 2-bus, 3-bus &4-bus systems with HiSynch &HiSwitch. This is what made Hipulsethe best-in -class High Availability UPSsystem. Liebert Hipulse-ETM is anenhanced version of that Hipulse.5
Liebert Hipulse-ETM500kVA - 800kVAAC Power for Business-Critical ContinuityFlexi Power Walk-InLiebert Hipulse-ETM is designed tohave flexible power walk-in (anotherunique feature) by way of adjusting thepower walk-in from 5 seconds to 120seconds. This gives you the opportunity to have optimized motor generatorsizing (leading to reduced investmentfor you) and the user flexibility to havedifferent walk-in time period fordifferent paralleled UPS modules(offering user fle xibility).Temperature Compensated BatteryChargingLiebert Hipulse-ETM allows the user touse optional temperature monitoringkit (to be connected to the batterybank) to monitor the temperature ofthe battery and thereby controlling thebattery charging voltage. This helpsyou to protect the battery investmentby way of protecting the battery health.6Compact Active & PassiveFootprintsLiebert Hipulse-ETM is designed tominimize both the active & passivefootprints.As you know, the active footprint is thephysical, visible & actual floor spaceoccupied by the cabinet.
