It's good to know how much power is required at every stage in the design. This includes the data relay and management portion of the system.
Data Logger (CCA) Power Consumption
A Tigo CCA functions on wide input range of 10 - 25VDC (3 - 15W). On the average, the CCA (itself), consumes up to 3 Watts but running the TAPs require more power (per TAP). For this reason, Tigo supplies a 24V / 1A PS so the CCA will have sufficient voltage to share with all the TAPs in the design (up to 7 maximum).
For more information, see: Datasheet - Cloud Connect Advanced (CCA)
TAP Power Consumption
The power for the TAP is supplied by the CCA. A single TAP (or Gateway) can run on 5VDC - 25VDC, but the average consumption is only 0.5 Watts, per TAP.
- Input voltage range 5VDC - 25VDC
- Consumption 0.5W average, 1W peak

Maximum Power Consumption
According to Tigo's Datasheets:
This means that the total consumption equation for a 7x TAP system will be:
- Minimum: 3 Watts + (7 x 0.5W per TAP) = 3 W + 3.5W = 6.5 Watts.
- Maximum: 10 Watts + (7 x 1W per TAP) = 10 W + 7W = 17 Watts
Due to this dynamic range, Tigo's CCA uses a selectable power supply that yields an output of 12-24 Volt, at 1A. For a full review of Power Supply specs, see: AC Adapter / Power Supply Overview
