Linea HS Series Camera User's Manual Declarations of Conformity • 73
Power Supply Issues
For safe and reliable operation, the module input supply must be within +24V DC. +/-10%.
The power supply to the module should be suitably current limited, as per the current
specifications.
Assume a worst-case power consumption at 150% current rating for the breaker or fuse.
Note: The camera will not start to draw current until the input supply is above
approximately 20V and 200 ms has elapsed. If the power supply stabilizes in less
than 200 ms, then inrush current will not exceed normal operating current.
It is important to consider how much voltage loss occurs in the power supply cabling to the
camera, particularly if the power cable is long and the supply is operating at +24V -10% where the
current draw is highest.
Reading the input supply voltage as measured by the camera will give an indication of the supply
drop being experienced.
The module tolerates “hot” unplugging and plugging, though not recommended. Connect all
supplies before turning the supply on.
The module has been designed to protect against accidental application of an incorrect input
supply, up to reasonable limits.
With the following input power issues, the status LED will be OFF:
• The module will protect against the application of voltages above approximately +28 V. If
the overvoltage protection threshold is exceeded, then power is turned off to the camera’s
internal circuitry. The power supply must be recycled to recover camera operation. The
input protection circuitry is rated up to an absolute maximum of +30 V. Beyond this
voltage, the camera may be damaged.
• The camera will also protect against the accidental application of a reverse input supply up
to a maximum of -30 V. Beyond this voltage, the camera may be damaged.
• The module will not be power up below approximately 20V.
Declarations of Conformity
FCC, CE and UKCA conformance testing has yet to be completed. The prototypes must be used for
evaluation and demonstration purposes only. The prototypes cannot be sold and must be retuned
to TeledyneDALSA on completion of the evaluation and replaced with compliant standard
production units after general Release for Sale.
