Tycon Systems TP-SCPOE-2448-HP PoE adapter

24V in, 48VDC POE, 24VDC Secondary out, POE/Solar Charge Controller for 24V battery systems The TP-SCPOE-24xx-HP High Power POE/Solar charge controllers with dual inputs charge batteries from a POE source and also a secondary source like solar panels in order to provide redundancy and insure 100% uptime for critical applications. They have a built in POE inserter with regulated output. They have full electronic protections for short circuit, reverse current, over-voltage, over-charge and over-discharge. They control the battery charging current to prevent battery damage from overcharging. The Controller accepts up to 2.6A on POE input to provide up to 60W total power capability. It also provides up to 8A on the solar input.

The controller gives priority to the solar panel input so grid electricity consumption is reduced when the solar panel is outputting power sufficient to charge the batteries.The built-in over-discharge protection and low self consumption ensures the battery is not over-discharged, which greatly increases the life of the batteries. The load is turned off when battery voltage is 20V and turns back on when battery voltage reaches 22V.The controller has five LED indicators to give a quick visual status if current is being supplied by a POE source or solar panel, if battery is charging, If load output is turned on and a warning if battery is connected with reverse polarity.
Solar and Battery Connections are via 4 screw terminals for wire size up to 12AWG. POE Input and Output is via 2 RJ45 shielded connectors. There is a secondary voltage output connector on the back with 5 screw terminals for connecting other electronics to the controller using up to 12AWG wire. The controllers are externally fused with a standard replaceable fuse.
