Bypass Function,
Utility Mode to /
from battery Mode
|
The UPS uses the Input AC line as its stand-by
source. in case of an O/L
condition, the UPS will automatically transfer
to the bypass line, if healthy
input conditions exist, within 4 msec (2.5ms typ.)
to ensure that the critical
load(s) continue to operate
