‘’ When I switch off the power for Homage UPS, the desktop PC doesn’t restart but when power fails from WAPDA or power load shedding happens,the desktop always restart. Why this happens? Electricity supply is cut off in both the situations but the Homage UPS reaction is different in both the cases.’'
this is the quote i pasted here
1-This problem always happens with Homage UPS. The reason why this happens is, Homage UPS takes long switch over time from WAPDA to Battery backup.
2-When you yourself cuts off the supply for Homage UPS, computer does not restart. This is because UPS quickly switches over from WAPDA to batteries. But when electric supply fails due to load shedding, desktop computers restart. This is because, current is still flowing through the input of UPS. Homage UPS is very sensitive to extremely low voltage so, when load shedding happens, voltage drops from full 220 volts to 0 volts in 1/8th to 1/10th of a second, and this duration is fairly long enough to make the computer restart. If your computer power supply is designed to stop working if voltage drops below than 150 volts, your system will always restart on Homage UPS. But if it can work with voltage as low as 90-100 volts, there are much chances, your computer will not restart.
3-To decrease the UPS switch over time, it is necessary that it must not be very low voltage sensitive.
4-Homage has introduced two editions, VISION and MATRIX, both editions have the same problem of restarting the desktop computers.
5-It is clearly written in the manuals of HOMAGE UPS that desktop computer will restart if power fails.
