Low Power RTU

Over 4 years battery life is possible due to its world beating low power consumption. This is based on writing to the SD card 1/sec and reporting to the CDL SmartHub 1/hour so it’s a genuine real world battery life. What makes this possible is the quiescent state power consumption of less than 150 microamps!
