Power Requirements
This section contains power supply information for the Thermal FFV™ system.
WARNING
Make certain that before and during system setup the power plug is
detached from the power source, otherwise the system may be damaged,
the persons setting up the system injured, or both.
• Correct polarity to the system must be observed, or damage may result.
•
The Thermal FFV™ system requires 12 to 30 VDC current under load, 24VDC
nominal is preferred to reduce incidence of installation voltage sag issues.
•
Cable length and the wire voltage drop calculation should be performed prior to
power supply and cabling implementation. The largest practical power conductor
should be installed within the shortest distance between source and the Thermal
FFV™ to minimize voltage drop.
•
Circuit protection including fuses or breakers should be considered.
•
A power supply with minimal peak-to-peak ripple is suggested to minimize
power supply noise in the system.
NOTE: The current requirement will vary depending on payload. For this configuration, a 24V 5A
supply should be sufficient (24V 10A supply is available, RV P/N 200137). Note that not all
supplies perform similarly under transient load, test the power supply with the complete camera
system in the lab before performing field installation.
