[Tornado] Typical Power Consumption Values

[Tornado] Typical Power Consumption Values

Tornado radios always establish a full duplex connection as the system requires feedback to operate. Because of this we provide the following power consumption figures:
1) Rx in standby (listening for an incoming transmission), Tx Idle. (M-PoD)
2) Rx Active, Tx Active, with one active E & M interface, (normal NDL)

With the wide operating voltage range of the radios we prefer to specify power consumption and then the customer can calculate current consumption by dividing the power consumption by the operating voltage. There is very little variation in power consumption over the operating voltage range. 

1) Rx in standby (listening for an incoming transmission), Tx Idle, 1 active Ethernet connection
a. Radio, 6W (excluding interface converter)
b. Interface converter, 0.25W (feed from radio)
c. 4 wire audio interface, 1.25W
i. Note: this is with an active E & M interface, I don’t have figures without it up, actual consumption will be slightly reduced.
d. Total, 7.50W
2) Rx Active, Tx Active, 1 active Ethernet connection, with one active E & M interface. The radio consumes the same power whether it operates at QPSK or QAM256. We do not change output as we change modulation like some other manufacturers.
a. Radio, 24W (excluding interface converter)
b. Interface converter, 0.25W (feed from radio)
c. 4 wire audio interface, 1.25W
d. Total, 25.5W
