    v121c-4


    V121C-30 is an active 30W high-power PD module, following the IEEE802.3af/at POE standard protocol, with a maximum output power of 30W. V121C-30 module can process the 48V voltage of POE and convert it to output a DC 12V current to supply IP devices.
     
    V121C is a module series, which includes two models:
    V121C: The maximum output current is DC 2.0A.
    V121C-30: The maximum output current is DC 2.5A.
