FAQs
What is UPS?
UPS stands for Uninterruptible Power Supply and is a device that provides a continuous supply of power to protect critical loads from power failures or fluctuations.
What is the main role of UPS?
The main role of a UPS is to provide a backup power source to ensure that critical equipment can continue to operate when utility power is interrupted or unstable, avoiding data loss or equipment damage.
What are the types of UPS?
UPS is mainly divided into three types: offline, online and online interactive.
How to choose the power capacity of UPS?
When choosing the power capacity of the UPS, you need to consider the total power demand of the load, it is usually recommended to choose a slightly larger than the total load power of the UPS to ensure sufficient standby time.
How is the standby time of a UPS determined?
The standby time of a UPS depends on the battery capacity and load power. Standby time usually ranges from 10 minutes to several hours, and the specific needs can be determined according to the actual application scenario.
