DC/DC Converter

(Part number: PWS-0148)

This DC/DC converter takes an input voltage from 36 to 72 Volts DC and provides an output of 24 Volts DC suitable for powering any of the Afar products.  With isolated input you can use it for installations where only –48 Volts DC is available.  With a power rating of 15 Watts you can use a single DC/DC converter to power up to three co-located gateways.  When using an Afar radio in conjunction with a gateway, the same DC/DC converter can provide power to the gateway and the radio.

When ordered with a NetCrossing Gateway the unit comes with a 3 ft wire on the output terminals ready to connect to the gateway power jack.
