CONSNANT has officially launched the CNH330 series three-phase online uninterruptible power supply (UPS). This product utilizes pure online double-conversion technology and is designed for data centers, server rooms, critical industrial processes, and other applications with stringent requirements for power quality and continuity. It is designed to provide absolutely clean, zero-interruption power to critical loads.

Core Technology: Pure Online Double-Conversion Architecture

The core of the CNH330 series is true online double-conversion technology, recognized in the industry as the highest level of power protection. Its operation is as follows:

1. Rectification (AC/DC): The incoming three-phase AC power (mains) is first converted to DC power. This DC power charges the internal or external battery pack and powers the next-stage inverter.

2. Inversion (DC/AC): The inverter converts the DC power back into pure, stable, sinusoidal AC power with extremely high voltage and frequency accuracy to supply the load. This architecture completely isolates critical equipment from the grid, virtually eliminating all power quality issues such as voltage sags, surges, spikes, harmonic interference, and frequency fluctuations. The zero-millisecond transition time between mains and battery mode ensures absolutely seamless and continuous load operation.

Key Features and Technical Advantages

• Three-Phase Input/Three-Phase Output (3/3 Phase): Perfectly matches standard three-phase distribution systems in medium- to large-sized equipment rooms and industrial environments. This design provides robust power support and achieves phase-to-phase load balancing, significantly improving distribution efficiency and reducing stress on building power systems compared to single-phase solutions.

• High input power factor (>0.99) and low input current harmonic distortion (THDi <3%): These characteristics mean the CNH330 presents a near-ideal linear load characteristic to the grid. This significantly reduces the burden on upstream generators, avoids pollution to the distribution system, and reduces line and transformer losses, while meeting stringent industry compliance requirements without the need for expensive additional harmonic filtering.

• Ultra-wide input voltage (304V-477V) and frequency (40-70Hz) ranges significantly enhance adaptability to harsh power grid environments. This wide mains input range reduces battery activation times, effectively extending the battery life. It also ensures compatibility with various backup generators, reducing the complexity and cost of generator selection and configuration.

• Fully digital DSP control: Utilizing an advanced digital signal processor (DSP), the rectifier and inverter are fully digitally controlled, achieving faster dynamic response, more precise voltage regulation, and higher overall reliability and stability.

• Flexible expansion capabilities: Supporting the connection of external battery packs, users can flexibly configure the system based on actual backup time requirements (from minutes to hours) to meet different scenarios requiring delays or waiting for generator startup.

Typical Application Scenarios

The CNH330 series is an ideal power protection solution for the following high-availability environments:

• Enterprise data centers and server rooms
• Network Operations Centers (NOCs)
• Industrial automation control systems and precision manufacturing equipment
• Medical imaging diagnostic equipment (such as CT and MRI)
• Core hubs in the financial and telecommunications industries

Intelligent Management and Maintainability

• Comprehensive Monitoring Interfaces: Standard RS232 and USB communication interfaces, with an optional SNMP/web network management card, enable easy integration into existing network management platforms, enabling remote monitoring, parameter configuration, and safe and orderly shutdown.
• Preventative Diagnostics: Continuous self-diagnosis and alerting functions proactively identify potential risks, enabling predictive maintenance and preventing problems before they occur.
• Highly Maintainable Design: Key components utilize a modular, hot-swappable design, significantly reducing mean time to repair (MTTR) and ensuring extremely high system availability.

The CONSNANT CNH330 series three-phase online UPS, with its pure double-conversion technology, superior electrical performance, and high reliability, provides a solid power defense for modern critical infrastructure. It not only protects the power supply of hardware equipment but also serves as a core asset for ensuring business continuity, data integrity, and operational security.
