General description
NCore belongs to the Active Power Stations family, a new generation of power stations dedicated to telecommunications
operators.
It can accommodate: up to 3 AC or DC input modules of 800W each for a total of 2400W; a battery management module
and 5 output modules with 4 ports each individually manageable. The management system, simple and immediate, allows
remote control of commands and monitoring.
Main features:
 Easy plug-in and installation
 Fully modular, allow infrastructure expansion (up to 20 devices)
 Remote management: saving time and reducing installation costs
 Output voltage: 12V, 24V, 29V, 48V and 54V
 Battery management module for lead and lithium technologies.
This module allows complete remote management of the NCore and also provides the Web, SSH and SNMP interfaces.
Each module can operate at a different output voltage, all the ports of the same module have the same voltage and can
be controlled to turn on or off.
This module allows you to charge lead or lithium batteries. It acts as a backup power source in the event of a power outage,
as current flow goes both ways from the NCore (it will charge the batteries or draw current from them if necessary).
You can choose between alternating current and direct current sources. It is also possible to opt for a mixed solution.

Base unit
The base unit has the capacity to install up to 5 output modules and 3 input modules in the provided housings. In addition
to the battery management module.
On the front you can see the OPT function button and the 3 LED monitors: OPTION, STATUS and ALARM.
To install the modules, we simply have to remove the metal cover and insert the desired modules. Screws are provided for
fixing on the upper face and avoiding accidental removal of the modules.
It consists of digital inputs/outputs and integrated relays, to which the “Event Management” function can be associated.
Grounding connector to protect people and equipment.
The slots indicate the presence of a fan inside the NCore to facilitate heat dissipation. In total it has 4 fan coolers.

Modules
DC Outputs
They have a current and voltage sensor that allows individual monitoring and control of each of the ports.
Standard
The output voltage is unregulated, so it provides exactly the voltage of the output rail, which is usually the output of the
54V power supply.
However, as it is not internally stabilized, the output voltage could drop, as in the case of battery power or due to too high
current draw.
The output ports are not isolated from the input rail, battery, or other standard ports (including other modules).
Adjustable
It is a module designed to adapt to various voltages of use, and keep them stable regardless of the load or type of power
supply.
You can choose, via software, the output voltage from three default values: 29, 48 or 54V.
The outputs are isolated from the input rail and other modules, but not from each other.
Special case -48V
There are installations that require a -48V power supply, this option is perfectly feasible with NCore. We simply have to
choose an isolated ADJ module with the following product code: NCORE-OUT-ADJ
In this module it will be possible to select, via software, an output voltage of 48V for all the ports. So, simply by reversing
the connection wires to the ports, we will have -48V.
ATTENTION: Special attention should be paid to the fact that the module ports are isolated from the input rail and other
modules, but not from each other. This means that if we connect a -48V device to port 1, we cannot connect another device
with a + 48V voltage to the other ports of the same module. This would cause a short circuit.

12V
It is a module designed to supply a single fixed 12V voltage and keep them stable regardless of the load or type of power
supply.
The ports are isolated from the entry rail and other modules, but not from each other.
24V
It is a module designed to supply a single fixed voltage at 24V, and keep them stable regardless of the load or type of
power supply.
The ports are isolated from the entry rail and other modules, but not from each other.
General Purpose Input/Outpu GPIO
GPIO is a hardware interface that allows microprocessors to interact with another external device.
This pin group is controlled by the NCore device software.
All pins share the same power supply, so pay attention to possible polarity / ground reference conflicts.
The status of the pins is not persistent, therefore in case of hardware restart or firmware update they could lose the status,
to reacquire it after restart / update is completed.
Below is the detail on how to use them:
Output pins: A2 ~ A5
GND pins: A1 and A6
Use pins A2 to A5 and GND: pins A1 and A6, as a reference when connecting to other devices. This voltage is isolated from
the power supply and internal logic.
The maximum output voltage is 5V. The current is internally limited to a value of 10 mA.
Input pins: B1 ~ B5
GND pins: B1 and B6
Connects pins B1 to B5 to pins GND: B1 and B6, through a controlled switch (transistor, mosfet, relay). It is not necessary to
limit the current, it is already internally limited.
It is not necessary to power the circuit, it is already connected and internally isolated to the +5V supplied.
To ensure correct operation, limit the voltage drop on the chosen interruptor to 1V max; select a switch that resists up to
at least 6V.
Integrated relays:
Relay 1: Pins from C1 to C3
Contact Function
C1 NC relay 1
C2 Common relay 1
C3 NO relay 1
Relay 2: Pins from C4 to C6
Contact Function
C4 NO relay 1
C5 Common relay 1
C6 NO relay 1
These relays are independent and isolated from each other.
The current rating of the relays is: 3A @ 250V.

Battery management module
The battery management module regulates the battery charging voltage and current and connects and disconnects the
battery according to the operating conditions to guarantee the energy required by the load.
It is not necessary to enter battery data or predetermined charge curves, since it is the NCore itself that calculates
automatically. It is enough to set the maximum charge current and the type of battery connected from the interface.
Charging phases
The module performs three charging phases that will be adapted to the type of battery chosen:
1. First charging phase, at constant current
2. Second charging phase, at constant voltage
3. Third phase of charging, maintenance (deactivated in the case of lithium batteries)
Thermistor
The module has the possibility to connect an external temperature sensor (called thermistor) to monitor the temperature
of the batteries. This sensor is supplied with the battery management module.
A longer thermistor can be connected. We just have to make sure that the thermistor is compatible with the NCore curve
(10 KOhm, Beta coefficient 3380, NTC thermistor).
The thermistor is used to correct the battery charge curve, automatically compensating for temperature variation.
If the batteries reach a temperature outside the recommended limits, the use of the external thermistor protects the
batteries by suspending the charge.
It is possible not to use the external thermistor by selecting the use of the internal one from the interface. In this case, the
system considers that the batteries are set at 25 ° C, does not adapt the charging curve and does not interrupt charging in
case of overheating.
ATTENTION: The use of the internal thermistor, in the presence of high external temperature, could cause irreparable
damage to the batteries and to that which is in the vicinity.
