D Series High-Frequency Online UPS 1~3kVA

Product profile

Digital Series UPS adopts dual-conversion online design, intelligent MCU / DSP precision control; when mains is interrupted or restored, UPS transfer time is zero between main mode and battery mode, effectively ensuring the reliability of load operation.


Basic Features

Online-type design, zero transfer

Digital Series UPS adopts dual-conversion online design, intelligent MCU / DSP precision control; when mains is interrupted or restored, UPS transfer time is zero between main mode and battery mode, effectively ensuring the reliability of load operation.

High quality sine waves (THD<3%, linear) can be output either in mains mode or battery mode to provide the best power supply for the load.

energy-efficient

PFC power factor correction design and IGBT transformation technology are adopted, the input power factor is 0.99, and the overall efficiency is 90%.


Detection and self-protection function

Digital Series UPS can simulate the power failure and enter the battery mode. This function can be executed at any time through "self-test button" on the panel, or with random monitoring software; perfect self-protection function, peak current and short circuit protection design, super load impact resistance.


TVSS function

Namely, TRANSIENT VOLTAGE SURGE SUPPRESS burst wave voltage protection function. Utend FAX. TELEPHONE, MODEM network and other conversion protection.


DC start function

In the state of mains power failure, if UPS is needed to start the computer or other load equipment, Digital series UPS can be directly started in battery mode, making the use of UPS more convenient and reliable.


Automatic bypass / manual bypass / maintenance bypass (optional)

In addition to the automatic bypass function, the Digital series UPS also has the function of manually setting the bypass on the panel keys; when necessary, the manual maintenance bypass can also be optional for online maintenance.


Optional lightning protection function

Optional D class lightning protection device, with surge protection, lightning protection design, effectively protect the equipment from lightning interference.


EPO emergency shutdown function (optional)

Optional EPO switch to realize emergency shutdown of UPS.


Rich and humanized LCD / LED content display

UPS operating status (mains mode / battery mode / bypass mode), input and output, battery power, load size, and failure code, etc., at a glance.


Extended time type power supply design

Digital Series UPS fully provides extended time machines for users to choose from. The appropriate battery pack can bring the discharge time of the UPS to about 8 hours to meet the requirements of different power grid environments. Digital Series UPS extended time machine in addition to the discharge time to extend the battery recharge capacity is also very strong, can provide about 3 ~ 4A initial charging current (can also be selected according to user needs, a larger charging current).


Can be used with a generator

The ultra-wide input voltage and frequency range enable Digital series UPS to be used with mainstream brand generators to extend the use time and effectively remove the impure power generated by the generator, providing safe and stable power supply for the load.


Adaptable perceptual load

Digital Series UPS allows for sensitive load.


Random monitoring software

Rs 232 communication interface (optional USB interface), random monitoring software, to realize the intelligent management of UPS by users.


Equipped with Intelligent Slot intelligent slot for remote monitoring (optional)

Digital Series UPS is equipped with-Intelligent Slot smart slot, users can choose SNMP network card to realize centralized monitoring and remote monitoring and other functions.
