Power requirements
Universal (self-switching) AC/DC input, automatically recognizes supply voltage:
•
18VDC to 100VDC
•
85VAC (RMS) to 250VAC (RMS)
•
One pair of wiring terminals accepts either AC or DC power
•
One internal ground lug for power-supply ground wiring
•
Maximum load conditions:
—
—
Note
For DC power:
•
Power requirements assume a single transmitter per cable.
•
At start-up for in-rush current, the power source must provide a minimum of 2.0 amps
of short-term current (1 ms) 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 0.2 amps.
Cable sizing formula
M = 18V + (R x L x 0.2A)
•
M: minimum supply voltage
•
R: cable resistance
•
L: cable length (in Ω/ft)
Typical power cable resistance at 68 °F (20.0 °C)
