48V 100Ah Batt, 48V 600W (UPS-STL48-100-600)


Item# UPS-STL48-100-600

The UPSPro® STL48-600W series outdoor enclosures are designed for applications that require a flexible backup power source in order to maintain uninterrupted service to customers. The enclosure is powered from 120/240VAC. It is also solar ready so a solar panel can be added as an alternate power source or to extend backup time. Features include 12V/24V/48VDC configurable output, an advanced 60A MPPT battery charge controller to protect against overcharging or over-discharging of the valve regulated sealed lead acid AGM batteries. Enclosures have multiple ports for CAT5 cable, antenna cables/connectors or other cabling. They are vented to prevent a residual buildup of hydrogen gas.

There is some space inside the enclosures for customer electronics such as controllers, wireless AP or CPE cards, sensors, inverters, etc. There is a 1U rack mount feature in the enclosure for rack mounting. Equipment runs on battery power which isolates it from power line surges which is a main cause of outdoor equipment failure.

A typical high power wireless access point with average power consumption of 8W will run 40 hours on a 52Ah battery at room temperature or 28 hours at -20 deg C.
