UNILINE all - in - one D-SERIES UPS

Advantage

• Ideal for a wide range of applications with its high technology, high reliability and efficiency and     functional structure.
• IGBT rectifier and inverter based, low THDi, high input power factor (PF >0.99); manufactured from 40 to 300 kVA single modules.
• D series UPS’ are parallelable.

Lower overall cost of ownership with high efficiency
The more efficient the UPS the less electrical bill you pay.. Since a true online UPS runs through energy conversion to supply its load, a percentage of the Input power is dissipated in the form of heat. An efficient
system keeps this loss to minimum so that the gain becomes high to supply maximum possible energy to the load. D Series UPS provides up to 93% efficiency due to high input power factor and inverter design. As a result overall costs decrease and lifespan of the system gets longer.

IGBT Rectifier with PFC
(Power Factor Correction)
With the aid of advanced IGBT rectifier, input power factor close to 1 (>0.99) and input current harmonic distortion less than 5% are achieved resulting in reduced costs. Ensures clean and sinusoidal input current, avoids pollution of the upstream power supply.

Intelligent Battery Management-Guarantees
Enhanced Battery Life
DSP controlled battery management provides the possible maximum battery lifespan. Battery monitoring gets real time information of battery capacity and remaining time that facilitates you to proactively plan maintenance operations to avoid any unexpected failures. Besides, UPS tests the batteries at certain adjustable intervals without switching off the rectifier
thus even if the batteries malfunction; it guarantees consistent operation of inverter for the critical loads supplied. Temperature compensated battery charging continuously monitors temperature changes in battery cabinets and adjusts the charging rate accordingly that greatly extends the battery life. Moreover, “Hot Swap” feature is available allowing battery change without disconnecting the UPS.

Total Digital Control System: In D Series UPS structure, in order to control and operate all power stages at their ultimate performance, two DSPs are dedicated. Various complex feedback algorithms, data acquisition, communication protocols are sensed by simultaneously working DSPs. The DSP controlling technology supplies useful features such as high efficiency and reliability.

Interactive display: A gorgeous user interface consists of interactive multi-lingual displays. The display above shows energy flow over its mimic diagram and the position of the circuit breakers. all the parameters of input/output and battery. Menus are observed on this LCD.
Features of D Series

• Parallel Operation
• Parallel feature is optional depending on customer requirements
• Each unit fitted with a bypass static switch
• An extra isolated parallel board
• Accurate current sharing by using DSP based advanced algorithm
• Ring connection Sensing the remove of the parallel cable
• Hot swap/ Easy power upgrade
• Observing the whole system on each unit’s LCD panel
• Starting/stopping the whole system on each unit’s front panel
• Automatic bypass transfer when external by pass switch used
• Synchronization of two separate parallel groups/units
• Communication solutions: A wide range of common communication options are available with D Series UPS that ensure your command and control over the installed UPS systems wherever they are located worldwide.
• SNMP: Network Solution
• Dry Contacts (Programmable Relay Unit)
• Custom Contacts
• Connection with EPC with RS232 and RS485 ports
• Remote Monitoring Panel ‘Modbus

Single or dual input operation: The dual input power allows the user to take advantage of a secondary power source. In this configuration, while feeding the rectifier input from the main source, the static and maintenance bypass can be fed from a secondary source. Each unit is facilitated with this feature that can be achieved with a little modification.
