power module
start delay (s)
UPS to control the interval that
each rack (or module) transfers
from battery mode to normal
mode, which reduces the impact
on the generator or power grid. In
the case of battery undervoltage,
the system automatically shortens
the delay for transferring to
normal mode to 1/8 of the normal
delay to accelerate the transfer
and prevent battery
overdischarge.
Intra-rack power
module start delay (s)
can be set
to a value ranging from 0.5 to
120.
Inter-rack power module
