CX22B / CX22B-W A3169-8.0 HBM: public 17
4.1 Voltage supply
Apply a supply voltage of DC 10 - 30 V to connector
X104 (see Fig. 5.1). Use a voltage supply with sufficient
power, in case the QuantumX modules connected to the
CX22B‒W or devices such as GPS sensors, cameras or
data memory directly connected to the unit also need to
be supplied with power.
The DC voltage supply must be a SELV voltage supply,
meeting the requirements of IEC / EN / DIN EN 609501.
The supply voltage must be protected by an adequate
DC fuse (e.g. LITTELFUSE KLKD 6, LFPHV001) with a
maximum current of 5 A.
Notice
When modules are installed in a vehicle, we recommend
connection to a separate battery or integration of an unin
terruptible power supply (UPS), as battery voltage is par
ticularly likely to fall below 10 V when a combustion en
gine starts up, which would automatically cause the
modules to restart.
HBM offers the NTX001 power supply for laboratory or
general steady-state operation. On the primary side, this
provides a selection of international connector types and
24 V and 30 watts on the secondary side. A CX22B‒W
and one additional module can be supplied in this way.
See the respective module data sheets for precise details
of performance.
The Data Recorder can also be supplied with voltage by
a (FireWire) module group.
