Line Interactive UPS

Prostarm is a leading manufacturer of line interactive UPS systems in India. We specialize in building line interactive UPS systems that are best suited for use in Indian climatic conditions and are delivered at price-points that meet the expectations of Indian businesses across diverse sectors and sizes. Apart from working to deliver a pure sine wave output, our UPS system comes with features such as stable eco-mode and no-load shutdown, humanized alarm systems, cold start, and the capability to auto-restart when mains power is restored. Prostarm supplies line interactive UPS systems between the capacity range of 500 VA ~ 3000 VA. Line interactive UPS systems are a mix of the online and offline UPS systems, and bring some unique advantages. They are best suited for applications that typically face voltage fluctuations. These systems incorporate an automatic voltage regulator or a tap-changing transformer. This allows line interactive UPS systems to provide power conditioning. They can step up or step down the incoming line voltage without shifting to battery power. Some line interactive UPS systems might draw power from the batteries to correct power fluctuations. In such cases, they might utilize the batteries more often than online UPS systems. Apart from providing power conditioning, line interactive UPS systems also act as reliable power backup units during power outages.

Line interactive UPS systems are deployed mostly in rackmount applications below 5000 VA. They also have power filtering capabilities. Thus, line interactive UPS systems are able to correct the most serious long-term voltage sags or spikes without draining the batteries. As the line interactive UPS system reduces the number of transfers to the battery, the service life of batteries too is extended. Prostarm line interactive UPS systems are highly efficient, at around 97% when there are no other problems with the power line.

In normal circumstances, power is supplied to the load from the main power supply of the system. In the line interactive UPS system, the inverter is constantly engaged in the output and thus always remains on. When the AC input is normal, the inverter operates in reverse, working to charge the batteries. When the power fails, it switches to drawing power from the batteries. In such as situation, the load is disconnected from the line by a static switch within the line interactive system, and the bidirectional converter supplies energy from the batteries.

• Cost-Effective: More affordable compared to Double Conversion UPS.
• Energy Efficient: Consumes less power as it does not convert AC to DC continuously.
• Longer Battery Life: Since it does not switch to battery mode frequently, it reduces battery wear.
• Good for Moderate Power Issues: Effective for locations with moderate voltage fluctuations.
• Lower Operational Costs: Requires minimal maintenance and cooling requirements.
