Power requirements

Self-switching AC/DC input, automatically recognizes supply voltage:
• 85 to 240 VAC, 50/60 Hz, 6 watts typical, 11 watts maximum
• 18 to 100 VDC, 6 watts typical, 11 watts maximum
Note
For DC power:
• Power requirements assume a single transmitter per cable.
• At startup, 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
• R: cable resistance
• L: cable length (in Ω/ft)
