Splet13. jul. 2024 · A PoE injector, also called midspan or PoE adapter, can be implemented to make a non-PoE compatible switch work with PoE devices by powering compliant devices over a single Ethernet cable. Ease of installation: simply connect the PoE injector to the PoE endpoint and to an Ethernet switch to provide data and power. SpletTo build a single switching buck supply, as show in the circuit below, you will need the following parts (about $15): 1 x 22uF Cap - Link 2 x 1000uF Cap - Link 1 x 680uH Inductor - Link 1 x 10k Res - Link 2 x 100k Res - Link 1 x IRF9Z34N PMOS - Link 2 x 1N5818 Diode - Link 1 x LT1632 Opamp - Link You have the option of building two supplies.

SpletThe series resistance of zener can be calculated by the following equation-. R1 = (Vs-Vz)/Iz. Where, Vs = maximum supply voltage. Vz = zener voltage. Iz = zener current. For calculating R1 the Zener current needs to be calculated as follows –. Maximum Power dissipation of zener diode, Pz = 250mV. Zener voltage, Vz = 5.6+4.7= 10.3V. SpletStep 1: Open the Plastic Case of the Power Supply. First you need to pry open the plastic case of the power supply. For laptops, these are built as bricks, fully enclosed, sometimes the plastic is welded.
