- UPS (uninterruptible power supply) how to calculate the power supply, such as 100W electrical power can be how long?
- Power supply time and your battery capacity is proportional relationship, and battery life is inversely related. But also depends on the load you bring, with a lot of time shorter, with the opposite of the contrary.
- Because the power failure, the company's financial department to buy two Hills 500i UPS Do you need to turn off the UPS after work? The Thank you Also after the power outage, the computer and other equipment is turned off, need to shut down the UPS?
