The E11B Hybrid UPS is a versatile option for businesses with multiple locations, thanks to its wide input voltage range of 110V to 300V (*) and input frequency range of 40Hz to 120Hz. It can operate efficiently in various regions with different power supply standards, making it a reliable choice for customers with unstable power sources.

Reduce The Number Of Battery Runs

One of the advantages of the E11B’s wide input voltage range is its ability to reduce the frequency of battery operation. Other products on the market may have to rely on battery power more frequently due to unstable power sources, which can shorten the lifespan of the battery. However, with the E11B, customers can expect to maintain a battery lifespan of up to five years at a surrounding temperature of 25℃, even in areas with unstable power sources.


Stable Power Supply with Built-in Inverter

E11B wide input voltage range related to stable output voltage

The E11B has a built-in inverter, which ensures a stable power supply by converting input voltage fluctuations to a constant output voltage. For instance, if the input voltage is rated at 220V, the device can still provide a stable 220V output voltage, even if the input voltage fluctuates between 110V and 300V. In the event of a power outage, the device switches to battery power seamlessly, ensuring an uninterrupted power supply.


In summary, the E11B is an ideal choice for customers who require a stable power supply in environments with significant power fluctuations. With its wide input voltage range and built-in inverter, the device provides a reliable and uninterrupted power supply, while also maintaining the lifespan of its battery.
