INSTRUCTIONS
1) Description:
NCP12 is a Super Capacitors Module providing up to 7.6kJ (2.1Wh) energy storage capability. It can be used to replace batteries for short term backup
function.
2) Installation:
use DIN-rails according to EN 60715. Installation should be made vertically (see Fig.4). For better device stability fix the rail to the wall close to the point
where the device is to be mounted. In order to guarantee sufficient convection, we recommend observing a minimum distance to other modules (see Fig.3).
3) Connections:
the device is equipped with pluggable screw terminals. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off
input power and waited for capacitors discharge.
In order to comply with local certification, use appropriate copper cables of indicated cross section, designed for an operating temperatures of
60°C for ambient up to 45°C
75°C for ambient up to 60°C
90°C for ambient up to 70°C.
Strip the connecting ends of the wires according to the indication on Fig.5 and ensure that all strands of a stranded wire enter the terminal connection.
4) Protections
: To prevent damage in case of reverse polarity or short circuit the device is protected by a user replaceable 30A/32V ATO blade fuse
.
For continued protection replace with same type and ratings of fuse only.
The maximum allowed charge voltage is 16VDC with a temporary overvoltage of max. 17VDC.
Exceeding these values will decrease product life dramatically and possibly triggering the overvoltage protection leading to fuse failure.
5) Series and parallel connection:
To increase the backup time and / or the available current several NCP12 can be connected in series / parallel arrangements. From the
user point of view the NCP12 is exactly equivalent to a 12V battery so that every series / parallel combination performed with 12V batteries can be done also with
NCP12. When used in conjunction with DCW20 UPS module the maximum number of NCP12 connectable in series is 3, because of the maximum charge voltage
limitation of the DCW20.
6) Safety precautions:
NCP12 can provide extremely high current when short circuited,
do not short circuit.
A short circuit when the NCP12 is charged will lead to fuse
failure. When NCP12 is fully charged at 16VDC it will remain charged for days, avoid storing or shipping when not fully discharged before
; do not short circuit
to
discharge NCP12. Charging NCP12 at voltage above 17VDC can lead to severe damage to the unit.
When connecting several NCP12 in series / parallel please discharge every NCP12
; never connect in parallel a charged unit with a discharged unit;
fuses of both units
will fail.
7) Operating temperature:
is recommended using in the following conditions
-40°C…+85°C when the environmental conditions is above 65°C derating voltage -120mV/°C.
8) Warranty:
NCP12 is guaranteed free from factory defects for the time specified in the “Sales Conditions”.
Failures caused by misuse, external and/or abnormal events (i.e. overvoltage, over temperatures) or non-respect of above parameters and standards, are not covered by
warranty. Opening the housing of the product makes warranty to be no longer valid.
