Bob4129 0 Posted December 29, 2011 I recently purchased an inexpensive poe switch, TPE-S44. Is there a standard output voltage for these devices to power cameras or is there an adjustment to change the voltage? I looked at the manual online but see no reference to adjust to the correct voltage. The manual mentioned the wattage limitations for each port, but no mention of voltage. Thanks, Bob Share this post Link to post Share on other sites

Thanks, Bob The 802.3 af or newer 802.3at POE standards specify a voltage range for the PD (powered device) of 37-57 volts for AF and 42.5 -57 volts for the newer AT standard. The PD typically has a set resistance value that calls for a set voltage it needs. You don't have to set anything...as long as everything is standards-compliant, it just works, assuming your cabling is correct. Share this post Link to post Share on other sites
