The power module for the TSF-A2 series. It supports dual redundant power input (PSU1 / PSU2), has a built-in solar controller and charges 12 V or 24 V lead-acid batteries, over a −40 to +75 °C operating range.

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.
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.
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.
Tell us the load, the solar conditions and how long it must ride through an outage, and we will help estimate panel and battery capacity.
