Industrial environments demand robust and reliable power protection solutions. Even minor power fluctuations or outages can disrupt critical processes, leading to costly downtime and potential safety hazards. EnerTech’s 3-1 Online UPS system is meticulously designed and manufactured to address these demanding industrial applications.

EnerTech ETXi Series 3-1P Online UPS provides a perfect solution for critical power applications such as networks and servers, small and medium data centers, telecommunication. ETXi Series UPS available in the 10-80 kVA range with on-line double conversion technology and parallel redundant configuration.

Experience the EnerTech Best 3-1 Online UPS system – the ultimate solution for reliable, cost-effective, and eco-friendly power protection for your critical equipment.

EnerTech is the manufacturer of three distinct 3-1Phase Online UPS system models, each using a different technology to bridge the gap between uninterruptible power outages:

  1. SCR (Silicon Controlled Rectifier) Based Online UPS: This cost-effective ETXi SCR Series option uses SCRs for power conversion. While reliable, SCRs introduce some distortion into the output waveform. However, EnerTech’s advanced design minimizes this distortion, making it suitable for applications that are not sensitive to waveform purity.
  2. PFC (Power Factor Correction) based UPS: The ETXi PFC Series uses PFC-based Online UPS system active power factor correction to provide significant performance improvements. This technology ensures that the UPS draws a clean current from the grid, reducing energy consumption and heat production. This reduces operating costs and reduces environmental impact.
  3. IGBT (Insulated-Gate Bipolar Transistor) based UPS: Representing the pinnacle of EnerTech’s 3-1Phase Online UPS ETXi IGBT series, the IGBT-based model boasts superior performance resulting in faster switching speeds and conduction lower losses compared to SCRs. This translates into a cleaner output waveform with less distortion, making it ideal for critical applications that require the highest levels of efficiency, such as data centers and medical facilities.

EnerTech is the leading name among the online UPS system manufacturer and supplier brings solutions with built-in galvanic isolation via transformers. The transformer eliminates the problems associated with common mode noise, neutral, phase reversal and earth potential drifts which can cause irrecoverable loss. We are among those Indian online UPS suppliers with the capability to offer customized power solutions as per customer requirements and site conditions.
