20kVA High-Frequency Online UPS for Critical Backup Power
The DAXIN ENERGY 3H20kVA high-frequency online UPS is built for applications
that require stable, reliable and continuous power protection. It is suitable
for industrial facilities, commercial buildings, telecom power rooms, data
centers, automation systems, security systems and other critical electrical loads.
True Online Double-Conversion Design
This 20kVA online UPS adopts true online double-conversion technology to isolate
connected equipment from grid fluctuations, voltage instability, frequency
variation and power interruptions. It helps protect sensitive equipment and
maintain stable operation during abnormal power conditions.
High Reliability Design
- True online double-conversion UPS architecture
- MCU + DSP digital control for stable and accurate operation
- Generator input compatible, recommended generator capacity is 2 times UPS capacity
- Optional output isolation transformer can be installed before shipment
- Standardmäßige EPO-Notabschaltfunktion
- Supports parallel operation up to 3 units for compatible models
- Configurable battery quantity from 16 to 20 batteries according to site requirements
- Charging current can be adjusted from 1A to 4A according to project needs
- Available with PF0.8 and PF0.9 power factor versions
- Supports automatic startup when mains power is restored
Comprehensive System Protection
The 3H20kVA online UPS integrates multiple protection functions, including
output overload protection, output short-circuit protection, inverter
over-temperature protection, low battery warning and battery overcharge
protection. These functions help improve system reliability and reduce the
risk of downtime.
Easy Maintenance and Bypass Operation
An optional manual maintenance bypass switch can be configured. When UPS
maintenance is required, the system can transfer to bypass mode without
interrupting the connected load, making maintenance safer and more convenient.
LCD-Anzeige und intelligente Überwachung
The LCD display provides real-time UPS operating status, input and output
parameters, battery information and alarm status. RS232 / USB communication
and optional SNMP network monitoring allow users to manage UPS operation
through intelligent monitoring software.
Designed for Demanding Environments
The circuit boards are installed in an enclosed structure and treated with
protective conformal coating, improving environmental adaptability for
industrial sites, tunnels, plazas, telecom rooms and other demanding
installation environments.
