WS-26-500-DC - FACTORY REFURBISHED
Managed passive POE Switch
500 Watt non-isolated DC power supply
(24) Gbps POE Ports
(2) SFP Uplink Ports
Designed to hook directly to battery bank not a power supply / charging unit.
NOTE: Always use an inline fuse or breaker.
If you have a 48V-54V power supply you should use the WS-26-DC unit.
500 Watt SMART DC power supply accepts 9V to 72V DC variable input while providing uninterrupted 24V and 48V POE
- 500 Watt POE budget when input voltage above 19V
- 450 Watt POE budget when input voltage above 16V
- 380 Watt POE budget when input voltage above 14V
- 300 Watt POE budget when input voltage above 11V
- 250 Watt POE budget when input voltage below 11V
WARNING: This switch is not designed to operate on negative 48V site, using -48V DC will damage the switch as it does not have isolated input output power.
NOTE: Optional 19" rack mount kits sold seperatly
Designed with a rugged chassis and extended operating temperature range with a simple yet powerful user interface.
Monitor DC voltage and current into the switch from your batteries.
Monitors the DC power supply temperature with auto and programmable thermal shutdown.
Program the switch to shut down lower priority POE ports when batteries get low and to restore them when sufficient reserves return or when it detects charging has resumed from solar or wind.
If power gets too low it can be configured to shut down all POE ports and hibernate your remote site until it detects solar or wind charging has resumed and sufficient reserves are generated.
you can chose to run your batteries all the way down to 9V to keep the tower up or have it shut down in stages to preserve your energy.
Since we designed the power supply to have its own micro processor and to communicate to the switch itself we have full control over the power supply and all relative telemetry generated by sensors built into the power supply.
WARNING: If you drain 12V batteries below 10V you may need a 10A charger to recover.
