The I0ATPI43 is an indoor Power over Ethernet injector. It provides Gigabit Ethernet and DC power via a single Ethernet cable (Cat5e or better). This solution allows running just one cable from inside equipment to the outdoor radio instead of using two separate cables for power and Ethernet. The PoE injector has a built-in lightning and surge protection preventing transient over-voltages from damaging radio and user’s indoor equipment. Device also has an overcurrent and short circuit protection, and it is protected against reversed polarity of the input voltage. The injector has a built-in DC/DC converter, which can be switched on / off depending on customer setup. With the DC/DC converter switched on, the output voltage will be stabilized to 57V, regardless of whether the input voltage varies from 10 to 57V. It is designed to compensate the voltage loss in long cables or insufficient input voltage from power supply. In turn, the mode with DC/DC converter switched off is suggested in setups with maximum output power needed in harsh, hot environments. The power consumed by the injector as well as the heat dissipated, will be the minimum in this mode. The power supply providing input voltage should be stabilized in this case and ensure voltage as close to 57V as possible. The four various operating modes: with DC/DC converter switched on / off, and with output voltage stabilized to 57V or equal to the input voltage, can be set up using two DIP switches on the rear panel of the device. A brief explanation of these modes is placed on the top cover label.
