UPS-PL1248-40L_DESCRIPTION.html
The UPS-PL1248-40L outdoor enclosures are designed for applications that require a backup power source in order to maintain uninterrupted service to customers. The enclosure is powered over a CAT5 network cable via Power over Ethernet (PoE) using a PoE Supply/Inserter (included).
Features include an advanced battery charge controller to protect against over-charging or over-discharging of the valve regulated sealed lead acid AGM batteries or LiFePO4 Lithium batteries. Enclosures have multiple ports for CAT5 cable, antenna cables/connectors or other cabling. They are vented to prevent 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. Equipment runs on battery power which isolates it from power line surges which is a main cause of outdoor equipment failure.
Models are equipped with a Solar Ready controller so they can also be powered using solar panels in addition to or instead of the PoE power supply.
Multiple configurations are available for 12V or 24V systems with various battery storage capacities.
A typical 250mW wireless access point with average power consumption of 3.5W will run 15 hours on a 9Ah AGM battery. You can expect the same load will run 23hrs on a Lithium battery.
