Description

The Netonix® WISP Switch™ model WS-12-250-DC is designed specifically for the WISP industry with a rugged chassis and extended operating temperature range. WS-12-250-DC is 12 Port Managed POE Switch + 2 SFP Uplink Ports and Designed to hook directly to the battery bank, not a power supply. It features a simple yet powerful user interface providing the software features WISPs need in a switch.

WS-12-250-DC Monitor DC voltage and current into the switch from your batteries and 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. And you can choose 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 microprocessor 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.

48VH PoE Ports,Pins 1,2,4,5 (+) Pins 3,6,7,8 (-), 1.5A – Ports 01-04
** Note: Prior to Rev F 24VH was available on ports 1-4

NOTE: Always use an inline fuse or breaker.
NOTE: Optional rack mount kit sold separately

If you have a 48V-54V power supply you should use the WS-12-DC unit.
250 Watt SMART DC power supply accepts 9V to 72V DC variable input while providing uninterrupted 24V and 48V POE
– 250 Watt POE budget when input voltage above 12V
– 200 Watt POE budget when input voltage above 11V
– 150 Watt POE budget when input voltage below 10V

WARNING: These switches are not designed to operate on negative 48V site, using -48V DC will damage the switch as it does not have isolated input output power.
