Power is the single point of failure everyone forgets

Redundant dual input

PSU1 and PSU2 are independent inputs backing each other up. However thorough the control logic, a single power feed remains a single point of failure.

Solar and battery

A built-in solar controller accepts 10 – 45 V DC and charges at up to 3 A into 12 V or 24 V lead-acid batteries, so a remote station with no mains supply can run independently.

Wide temperature

A −40 to +75 °C operating range. Outdoor enclosures bake in summer and freeze in winter, and the power module's temperature rating often matters more than the controller's.
