The main difference between industrial online UPS and  low-frequency UPS is its design and functionality.

1. Design: Industrial online UPS is designed for industrial applications requiring high reliability and performance. Made from rugged components, it has a rugged construction that can withstand harsh industrial environments and has an IP42 protection rating. On the other hand, a regular low-frequency UPS is designed for general-purpose applications and may not have the same level of durability and ruggedness as an industrial UPS, which is rated IP20.

2. Power output: Industrial online UPS can provide continuous and stable power output even during power fluctuations or power outages. It uses double conversion technology, in which the input AC power is first converted to DC power and then converted back to AC power. This ensures clean and uninterrupted power supply to critical industrial equipment. The DC UPS is completely isolated from the mains and between the input and output, and the bypass is also equipped with an isolation voltage stabilizing function, which can prevent various power shocks and make it safer. On the other hand, an  low-frequency UPS may experience a slight delay in power switching during a power outage, and it only has output isolation, which may cause a momentary interruption in power supply.

3. Efficiency: Industrial online UPS is highly efficient and provides high power factor correction, which helps reduce energy waste and improve overall system efficiency. The power device has a certain margin, so it also has a higher overload capability and can cope with sudden load surges. In comparison,  low-frequency UPS may have lower efficiency and overload capabilities.

4. Monitoring: Industrial online UPS usually have advanced monitoring functions, such as remote monitoring, data logging and alarm notification. These features enable efficient management and troubleshooting of UPS systems.  Low-frequency UPS may have basic monitoring and control capabilities, or may require manual intervention for monitoring and maintenance.

5. Scalability: Industrial online UPS systems are typically designed to be scalable so that they can be expanded easily as the industrial facility’s power needs grow. This makes it suitable for large-scale industrial applications. On the other hand, a low-frequency UPS may have limited scalability options and may not be able to support high power demands.

To sum up, industrial online UPS is specially designed for industrial applications, providing continuous and stable power supply with high efficiency and advanced monitoring capabilities. It is designed to withstand harsh industrial environments and offers scalability options. Low-frequency UPSs, on the other hand, are suitable for general-purpose applications but may not have the same level of reliability, performance, and advanced features as industrial UPSs.
