57Alvium USB Cameras User Guide V4.6.1
Compliance, safety, and intended use
Camera power
Operating the camera beyond the specified range damages the camera.
Standard Alvium USB cameras are powered over USB. Alternatively, cameras can
be powered using the I/O connector at a maximum input of 5.5 VDC, using a
limited power source (LPS), according to IEC 62368-1 with minimum 1.5 A. The
camera is not intended to be connected to a DC distribution network.
• Make sure that USB 3.0 or 3.1 Gen 1 host controller cards, on-board host
controllers, or hubs provide sufficient current supply for the connected
cameras.
• Only use power supplies that meet the insulation requirement according to
PELV or SELV. For details, please refer to IEC 61140.
• We recommend using powered hubs, especially for multi-camera operation.
GPIOs
To avoid damage to the camera, keep maximum input voltage below 5.5 VDC and
maximum current below 12 mA per output. See Specifications on page 63 for
details. The maximum length for I/O cables must not exceed 30 meters.
Reverse polarity
If Alvium USB cameras are externally powered with reverse polarity, the cameras
can be damaged. See I/O connector pin assignment on page 277 for proper
external power connections.
JST-cables
JST I/O cables without shielding are designed to be used with bare board or open
housing Alvium cameras. The customer is responsible for an EMC compliant
design. For applications without an additional EMC housing, please use shielded
JST I/O cables with screw lock.
Ground loops
Unsuitable connections can lead to different potentials between the camera
system GND and the environmental shield/chassis GND caused by ground loops.
This can damage the camera and the connected devices or cause malfunctions.
