The APS-T Tower System is a high-tech True On-Line Double Conversion system. This traditional configuration provides a well-known solution that has been provided for many years. A simple LCD display allows the customer to check the UPS, load, and battery status. This system is available in 1kVA to 10kVA capacities with standard 5–10-minute backup or long-term backup.
The APS-T Tower System is a physically small On-Line double conversion UPS that retains all of the features normally associated with On-Line technology. But what exactly is On-Line double conversion technology, and why is it important? Simply put, “double conversion” is the process of rectifying the mains supply to a clean DC voltage and rebuilding it into a very clean and regulated AC voltage, with your critical load running from this clean no, break supply at all times.
I bought this ups and it’s very good in terms of build and power supply.
