The EnerTech HTXi Series 5kVA to 600kVA 3-3 Phase Online UPS system provides reliable protection for critical industrial applications from power disruptions. It uses an online double-conversion technology, transforming incoming AC power to DC and then back to regulated, clean AC, eliminating voltage fluctuations.

The UPS utilizes a 32-bit DSP system for precise power regulation and quick response to changes. IGBT-based Online UPS technology improves efficiency, reliability, and reduces input current distortion. With over 75% peak efficiency, the system conserves energy. Additionally, the EnerTech Best HTxi Series Online UPS can handle short-term overloads of up to 125% for 60 seconds and 150% for 5 seconds.

With the ability of EnerTech 3-3 Phase Online UPS to accept a wide range of input voltages, it can tolerate voltage fluctuations in incoming power supply without switching to battery. An inbuild galvanic isolation transformer protects equipment against ground faults and surge currents as well. The EnerTech Online UPS also has multi model capabilities which include Standalone Online UPS, Hot Standby Online UPS and Parallel Redundant Online UPS(N+1 | 1+1 Parallel Redundant UPS) for user specific operations depending on its requirements.

Standalone Online UPS: This is a double conversion online topology that offers high power ratings making it suitable for standalone application where continuously providing clean power to critical equipment.

Hot Standby Online UPS: This requirement aligns with hot standby operation since the wide input voltage range, together with efficient IGBT technology, allows for seamless switchover to battery mode during outages without significant impact on connected loads.

Parallel Redundant Online UPS (N+1 | 1+1): In addition, these units enable multiple 3-3 Phase Online UPS systems to be joined together in order to increase total capacity and redundancy like N+1 and 1+1 parallel redundant setups are necessary.

This EnerTech 3-3 phase UPS manufacturer that can be scaled according to the needs and monitored remotely. N+1 Online Parallel Redundant Online UPS units can be added in parallel to increase the power capacity as well as redundancy. There is a GSM/RS-485 communication for remote monitoring of UPS status so that proactive maintenance of the system can be done.

Moreover, this Online UPS has compatible with different battery types supporting various technologies, including Lithium-ion with MODBUS communication for advanced integration making it possible to have customised solutions for various backup power requirements. For details about voltage range, power factor correction, and specific battery charger features refer to the EnerTech HTXi Series Online UPS datasheet.


EnerTech make HTXi Series 3-3P online UPS (three-phase input and output) is designed to meet the power requirements of critical applications that require high power levels and high levels of reliability. 

There are several reasons why someone might need an EnerTech make 3-3P online UPS:

High Power Requirements: Some applications require high power, which is beyond the capacity of a single-phase input and output UPS. In such cases, EnerTech make 3-3P online UPS can be used to provide the required power.

Unbalanced Loads: Some loads are unbalanced, which means that they require a 3-phase power supply to operate correctly. In such cases, EnerTech HTXi 3-3P online UPS can be used to provide a balanced 3-phase power supply to the load.

Enhanced Reliability: EnerTech HTXi 3-3P online UPS systems are designed to provide high levels of reliability and redundancy. They typically come with multiple power modules, which ensure that the load is always supplied with a stable and uninterrupted power supply, even if one of the modules fails.

Reduced Energy Costs: HTXi Series 3-3P online UPS systems are typically more energy-efficient than single-phase UPS systems, as they can handle larger loads more efficiently. 

Compatibility with 3-phase Generators: In some locations, HTXi Series 3-phase generator may be the only available power source. In such cases, a 3-3P online UPS can be used to convert the 3-phase power supply to a stable and reliable power supply to power the connected devices.

Suitable for Large Data Centers and Industrial Applications: HTXi Series 3-3P online UPS is suitable for large data centers and industrial applications, where the power requirements are high and the need for reliable power supply is critical.

Overall, an EnerTech make HTXi 3-3P online UPS provides a reliable, efficient, and cost-effective power solution for applications that require high power or a balanced 3-phase power supply. It is ideal for critical applications that require high levels of reliability and uptime, such as data centers, industrial applications, and healthcare facilities.
