Mode of use
Priority
NCore allows to feed up to 20 different loads, more or less fundamental for the system in which it will be placed. Each port
is assigned a unique priority from 1 to 21: 1 corresponds to the highest priority, 21 to the lowest. There are 21 because even
the battery management module has assignable priority, as does an exit output. Ports assigned a lower priority will shut
down first in the event of reduced input power or partial faults, which do not preclude full system functionality.
By default, the priority is preset according to the numbering of the ports, the battery management module being last.
The user can modify the prioritization of each port through the interface.
Always On
Some essential loads can also be assigned a flag "Always On" to use the Proactive
4
mode. When configuring one or more
Always On loads, the NCore will prefer to keep them at the expense of the others.
Use this feature sparingly and only if it is really essential.
ATTENTION: If no load is set to “Always On” and “Proactive” mode is selected, in case of failure, all loads will turn off and
only the NCore will stay on.
Power management
The NCore is a product created and designed to enable intelligent management of the power supply of telecommunications
equipment.
It is important that these devices never stop working when in service, because they are difficult to reach and are not
constantly monitored.
For this, two modes of behavior of the NCore are expected in case of power outages:
Reactive
Proactive
Reactive
It is the default mode that allows the NCore to react to sudden external situations.
The NCore prefers the maximum number of charges that can be kept active with available power, rather than usage time.
It comes into play due to a power supply failure, in the event of a total power failure or low battery.
When operating, the NCore begins to shut down the loads one by one, starting with the one with the lowest order of
priority.
As soon as the power system is restored (even partially), it automatically restarts all possible loads, always in order of priority.
Proactive
ATTENTION: The Proactive mode exists and can only be activated in the presence of a connected battery.
Actively act to maximize survival time after extended power outages.
It is useful in the case that some devices are essential and you prefer to sacrifice others to prolong battery life, in the
absence of the network. So, the battery is used only for basic charges, while the other charges are temporarily disabled.
When the battery charge is insufficient to keep even critical loads active, the NCore automatically returns to Reactive mode,
shuts off critical loads with a lower priority, and then returns to Proactive as soon as the fault ceases and power is restored.
The system does not allow priority changes during a failure in Proactive mode.
Changes will be considered only at the next power outage. Therefore, the loads cannot be reactivated before the power
supplies have been restored.
To facilitate priority management when automatically switching between the two modes, Always On ports are
automatically assigned a higher priority level than the others.
