L10-80K3/1 Series UPS (3 Ph in 1 Ph out)
L10-80K3/1 series online UPS is the collection digitization, informationization, network as one of the high intelligent products, with powerful information acquisition system.
Key Features


 Pure sine wave output, true on-line dual conversion design

 Adopt 4 layer PCB, and SMD technology

 High efficiency IGBT (insulated gate bipolar transistor) inverter technology

The 6th generation low-exhaust and big-power IGBT with excellent high speed switch feature, high voltage feature and large current feature.

 Touch screen display, with the simple operation and intuitive data, optional display language and logo

 Set the work mode on the display directly, UPS mode, ECO mode, EPS mode

 Intelligent detecting function

This system microprocessor can continually detect power status online, the breaker status and all the working status of the circuit.

 It is completely capable to load from 0-100% while no need to change to bypass, which make sure the output reliable.

 Perfect protection

Input/output over/low voltage protection, input surge protection, phase sequence protection, battery over charge/discharge protection, short circuit protection, over-temperature protection and so on, as well as alarm function.

 Selectable battery inspection module

 Can test the single parameter and display on the LCD, battery failure will immediately alarm and inform the administrator.

 High-powered dynamic feature

Adopt kinds of feedback control such as instantaneous control mode and virtual value, not only reach the high dynamic adjustment, but also reduce the output voltage distortion.

 Optional input harmonic filter or 12 pulse rectifier

Effectively restrain the input THD, raise UPS input power factor and reduce the input THD current.

 Cold start

 Generator compatible

 Intelligent communication

With RS232 and RS485 standard collocation, optional SNMP and dry contact
