Description
3H30kVA High-Frequency Online UPS for Industrial Backup Power
The DAXIN ENERGY 3H30kVA high-frequency online UPS is engineered for
high-demand backup power applications that require stable, reliable and
continuous power protection. It is suitable for data centers, telecom power
rooms, industrial automation systems, commercial buildings, security systems
and other mission-critical electrical equipment.
True Online Double-Conversion UPS
The 3H30kVA online UPS adopts true online double-conversion technology to
isolate connected loads from unstable grid power, voltage fluctuation,
frequency variation, transient interference and power interruptions. It
provides clean and stable output power for sensitive equipment.
High Reliability Design
- 30kVA / 24kW rated capacity for medium and large backup power systems
- True online double-conversion UPS architecture
- MCU + DSP digital control for accurate and stable operation
- Generator input compatible, recommended generator capacity is 2 times UPS capacity
- Optional output isolation transformer can be installed before shipment
- Standard EPO emergency power-off function
- Supports parallel operation up to 3 units for compatible models
- Battery quantity can be configured from 18 to 20 pcs according to site requirements
- 12A ±10% charging current for 30kVA configuration
- Available with PF0.8 and PF0.9 power factor versions
- Supports automatic startup after mains power recovery
Comprehensive Protection Functions
The 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, reduce downtime and protect
connected critical equipment.
Maintenance Bypass for Easier Service
An optional manual maintenance bypass switch can be configured. When UPS
maintenance or fault inspection is required, the load can be transferred to
bypass power without interruption, making maintenance safer, faster and more
convenient.
LCD Display and Remote Monitoring
The LCD display provides real-time UPS operating status, input voltage,
output voltage, frequency, battery information and alarm status. RS232 / USB
communication and optional SNMP network monitoring allow users to manage UPS
operation through intelligent monitoring software.
Adaptable 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.
Typical Applications
- Data centers and server rooms
- Telecom power rooms and communication stations
- Industrial automation and control systems
- Commercial buildings and office facilities
- Security, monitoring and access control systems
- Medical, transportation and public infrastructure backup power
