The invention of the uninterrupted power supply (UPS) opened doors to numerous possibilities across industries. In the past, these systems were large and primarily designed for large-scale operations. Today, however, most people associate them with personal or office computers due to their compact size and reliable ability to maintain a steady power supply. With modern advancements in electronics, UPS systems have become more efficient and dependable. In the laser cutting industry, where precision and consistency are critical, uninterrupted power has immense value. At Eventa Power Technologies, we provide a wide range of online UPS for laser cutting machines. In this article, we highlight their importance, functions, and what makes us a trusted provider for different industries

Managing Voltage Variations

Many industrial facilities that operate on a 3-phase supply system have a higher capacity compared to the single-phase supply used in homes. The frequent switching of heavy equipment, combined with varied load conditions, increases the risk of voltage fluctuations, surges, and dips. Harmonic distortions can further affect power quality. Online UPS systems for laser cutting machines address these issues through AC and DC filters that remove distortions. At the same time, the rectifier corrects variations to deliver a stable supply to the machine.

Enabling Continuous Operations

The primary role of any UPS is to make sure the power supply is uninterrupted. Offline and line-interactive UPS systems achieve this by switching from the mains supply to battery power when required. Although the switch is fast, there is still some interruption for a brief period, which affects the precision operations of the laser cutting machines, where every microsecond counts. In such cases, online UPS systems are more useful as they avoid the interruption entirely by removing the switchover process. The load is continuously connected to the inverter so that the laser cutting machine can perform continuously.

DSP for Precision and Efficiency

A key breakthrough in UPS technology is the use of Digital Signal Processing (DSP). Unlike traditional microcontroller-based UPS systems, which require manual adjustments by engineers, DSP-based UPS systems are software-driven and allow precise, adaptive control in real time.

Advantages of DSP-Based UPS Systems:

Faster response to voltage changes and faults – In DSP-based UPS systems, all parameters are controlled through software, enabling instant adjustments. In contrast, traditional microcontroller-based UPS units require manual tuning through physical presets

• Higher efficiency – Intelligent control of the inverter and rectifier optimizes power conversion, reducing energy losses.
• Consistent output quality – Ensures stable voltage and frequency, critical for laser cutting machines that demand precision.
• Short-Circuit Protection for sensitive equipment – Prevents sudden current spikes from damaging high-value laser cutting components.
• Phase Sequence Correction for stable operations – Automatically corrects incorrect phase sequence, protecting motors and sensitive electronics from malfunction.
• Fewer components, higher reliability – A simplified design minimizes points of failure, increases UPS lifespan, and reduces maintenance requirements.

By integrating DSP, Enventa’s UPS systems deliver unmatched accuracy, protection, and long-term robustness, making them the ideal choice for modern laser cutting facilities.

Reducing Risk of Power Failures

Industrial environments often experience load variations and frequent switching of heavy machinery, which increases the risk of faults, failures, and downtime. Factors such as overloading, low voltage, harmonic distortions, or undersized UPS capacity contribute to these problems. Our online UPS systems are available in multiple input-output phase configurations, helping reduce the risk of failures and ensuring stable performance.

Minimizing Material Losses

An interruption in the power supply to a laser cutting machine can cause significant setbacks. Whenever it occurs, the design consistency suffers, materials are wasted, and rework becomes necessary. All these factors lead to losses of cost and time. With an online UPS, these risks are overcome, and the quality of cutting is protected.
