It is suitable<br \/>\nfor industrial facilities, commercial buildings, telecom power rooms, data<br \/>\ncenters, automation systems, security systems and other critical electrical loads.<\/p>\n<h3>True Online Double-Conversion Design<\/h3>\n<p>This 20kVA online UPS adopts true online double-conversion technology to isolate<br \/>\nconnected equipment from grid fluctuations, voltage instability, frequency<br \/>\nvariation and power interruptions. It helps protect sensitive equipment and<br \/>\nmaintain stable operation during abnormal power conditions.<\/p>\n<h3>High Reliability Design<\/h3>\n<ul>\n<li>True online double-conversion UPS architecture<\/li>\n<li>MCU + DSP digital control for stable and accurate operation<\/li>\n<li>Generator input compatible, recommended generator capacity is 2 times UPS capacity<\/li>\n<li>Optional output isolation transformer can be installed before shipment<\/li>\n<li>Standard EPO emergency power-off function<\/li>\n<li>Supports parallel operation up to 3 units for compatible models<\/li>\n<li>Configurable battery quantity from 16 to 20 batteries according to site requirements<\/li>\n<li>Charging current can be adjusted from 1A to 4A according to project needs<\/li>\n<li>Available with PF0.8 and PF0.9 power factor versions<\/li>\n<li>Supports automatic startup when mains power is restored<\/li>\n<\/ul>\n<h3>Comprehensive System Protection<\/h3>\n<p>The 3H20kVA online UPS integrates multiple protection functions, including<br \/>\noutput overload protection, output short-circuit protection, inverter<br \/>\nover-temperature protection, low battery warning and battery overcharge<br \/>\nprotection. These functions help improve system reliability and reduce the<br \/>\nrisk of downtime.<\/p>\n<h3>Easy Maintenance and Bypass Operation<\/h3>\n<p>An optional manual maintenance bypass switch can be configured. When UPS<br \/>\nmaintenance is required, the system can transfer to bypass mode without<br \/>\ninterrupting the connected load, making maintenance safer and more convenient.<\/p>\n<h3>LCD Display and Intelligent Monitoring<\/h3>\n<p>The LCD display provides real-time UPS operating status, input and output<br \/>\nparameters, battery information and alarm status. RS232 \/ USB communication<br \/>\nand optional SNMP network monitoring allow users to manage UPS operation<br \/>\nthrough intelligent monitoring software.<\/p>\n<h3>Designed for Demanding Environments<\/h3>\n<p>The circuit boards are installed in an enclosed structure and treated with<br \/>\nprotective conformal coating, improving environmental adaptability for<br \/>\nindustrial sites, tunnels, plazas, telecom rooms and other demanding<br \/>\ninstallation environments.<\/p>\n<h3>Typical Applications<\/h3>\n<ul>\n<li>Data centers and server rooms<\/li>\n<li>Telecom power rooms and communication stations<\/li>\n<li>Industrial automation equipment<\/li>\n<li>Commercial buildings and office facilities<\/li>\n<li>Security, monitoring and control systems<\/li>\n<li>Medical, transportation and public infrastructure power protection<\/li>\n<\/ul>\n<\/section>\n<section class=\"daxin-ups-specs\">\n<h2>Technical Specifications &#8211; 3H20kVA Online UPS<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Model<\/th>\n<td>3H20kVA<\/td>\n<\/tr>\n<tr>\n<th>Capacity<\/th>\n<td>20kVA \/ 18kW<\/td>\n<\/tr>\n<tr>\n<th>Input Phase<\/th>\n<td>Three-phase four-wire with ground<\/td>\n<\/tr>\n<tr>\n<th>Input Voltage Range<\/th>\n<td>110VAC \u00b13% at 50% load; 176VAC \u00b13% at 100% load; maximum 300VAC \u00b13%<\/td>\n<\/tr>\n<tr>\n<th>Input Frequency Range<\/th>\n<td>46-54Hz at 50Hz system; 56-64Hz at 60Hz system<\/td>\n<\/tr>\n<tr>\n<th>Output Voltage<\/th>\n<td>208 \/ 220 \/ 230 \/ 240VAC<\/td>\n<\/tr>\n<tr>\n<th>AC Voltage Regulation<\/th>\n<td>\u00b11%<\/td>\n<\/tr>\n<tr>\n<th>Battery Mode Frequency<\/th>\n<td>50Hz \u00b10.1Hz or 60Hz \u00b10.1Hz<\/td>\n<\/tr>\n<tr>\n<th>Current Crest Ratio<\/th>\n<td>3:1 max<\/td>\n<\/tr>\n<tr>\n<th>Harmonic Distortion<\/th>\n<td>\u22643% THD linear load; \u22645% THD non-linear load<\/td>\n<\/tr>\n<tr>\n<th>Transfer Time<\/th>\n<td>0ms from mains to battery; 0ms from inverter to bypass<\/td>\n<\/tr>\n<tr>\n<th>Overload Capacity<\/th>\n<td>100%-110%: 5 min; 110%-130%: 1 min; &gt;130%: bypass immediately<\/td>\n<\/tr>\n<tr>\n<th>Efficiency<\/th>\n<td>&gt;91% in AC mode; &gt;91% in battery mode<\/td>\n<\/tr>\n<tr>\n<th>Battery Type<\/th>\n<td>12V sealed lead-acid battery<\/td>\n<\/tr>\n<tr>\n<th>Battery Quantity<\/th>\n<td>16-20 pcs configurable<\/td>\n<\/tr>\n<tr>\n<th>Charging Current<\/th>\n<td>Default 4A \u00b110%; optional 1A \/ 2A \/ 4A<\/td>\n<\/tr>\n<tr>\n<th>Dimensions<\/th>\n<td>592 \u00d7 250 \u00d7 576 mm<\/td>\n<\/tr>\n<tr>\n<th>Net Weight<\/th>\n<td>28.5 kg<\/td>\n<\/tr>\n<tr>\n<th>Operating Temperature<\/th>\n<td>0-50\u00b0C; battery life may be shortened above 25\u00b0C<\/td>\n<\/tr>\n<tr>\n<th>Relative Humidity<\/th>\n<td>&lt;95%, non-condensing<\/td>\n<\/tr>\n<tr>\n<th>Operating Altitude<\/th>\n<td>&lt;1000 m<\/td>\n<\/tr>\n<tr>\n<th>Noise Level<\/th>\n<td>&lt;60dB at 1 meter<\/td>\n<\/tr>\n<tr>\n<th>Communication Interface<\/th>\n<td>RS232 \/ USB, supports Windows, Linux, Unix and Mac systems<\/td>\n<\/tr>\n<tr>\n<th>Optional SNMP<\/th>\n<td>SNMP network monitoring and power management support<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n<p><!--more--><\/p>\n<figure id=\"attachment_2232\" aria-describedby=\"caption-attachment-2232\" style=\"width: 982px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2232\" src=\"https:\/\/btrytech.com\/wp-content\/uploads\/2026\/07\/ups-power-solution-provider-english.png\" alt=\"DAXIN ENERGY online UPS key features including stable power, wide voltage range, energy saving and easy operation\" width=\"982\" height=\"664\" srcset=\"https:\/\/btrytech.com\/wp-content\/uploads\/2026\/07\/ups-power-solution-provider-english.png 982w, https:\/\/btrytech.com\/wp-content\/uploads\/2026\/07\/ups-power-solution-provider-english-300x203.png 300w, https:\/\/btrytech.com\/wp-content\/uploads\/2026\/07\/ups-power-solution-provider-english-768x519.png 768w, https:\/\/btrytech.com\/wp-content\/uploads\/2026\/07\/ups-power-solution-provider-english-18x12.png 18w\" sizes=\"auto, (max-width: 982px) 100vw, 982px\" \/><figcaption id=\"caption-attachment-2232\" class=\"wp-caption-text\">Key features of DAXIN ENERGY online UPS, including stable power, wide voltage range, energy saving and easy operation.<\/figcaption><\/figure>\n<p><!--more--><!--more--><\/p>\n","protected":false},"excerpt":{"rendered":"<p>DAXIN ENERGY 3H20kVA high-frequency online UPS is designed for industrial, commercial, telecom, data center and critical power backup applications.
