Power requirements
Self-switching AC/DC input, automatically recognizes supply voltage:
•
85 to 240 VAC, 6.5 watts typical, 9 watts maximum
•
18 to 100 VDC, 6.5 watts typical, 9 watts maximum
Note
For DC power:
•
Power requirements assume a single transmitter per cable.
•
At start-up, the power source must provide a minimum of 1.5 amps of short-term
current per transmitter and not pull voltage below 18 VDC.
•
Length and conductor diameter of the power cable must be sized to provide 18 VDC
minimum at the power terminals, at a load current of 0.7 amps.
Cable sizing formula
M = 18V + (R x L x 0.7A)
•
M: minimum supply voltage
