E. Time switch (for setting uninterrupted period)
The Time switch is used to set the waiting period (30s/360s) before sending the
PS_ON signal to shut down PC after AC power is off.
Warning! During this time the PPC-IPS will supply the PC with its battery to
ensure the loading PC works properly.
If the AC power resumes during this uninterrupted period (within 30s/
360s), the process for sending the PS_ON signal will be interrupted.
If the battery capacity is down to 15%, the PPC-IPS will immediately
send the PS_ON signal to turn off the loading PC. For this reason,
please ensure the battery has enough power.
The PPC-IPS has a software utility to adjust this period setting, and the
maximum uninterrupted period is strongly related with the loading PC
power consumption.
