Instructions for use:
Step 1 – Pick your PoE Standard. Don’t know what they mean? Check out our Dictionary. If you have an unusual PoE, you can use the 24 volt passive for 2 pair PoE.
Step 2 – Either select your cable type, our values match industry standard, or look it up yourself under the DCR of your cable and put it in the Alternate Ohms/1000 ft field.
Step 3 – Pick your voltage. You’ll want to check your datasheets for IEEE compliant products because they can range from 44 to 56 volts.
Step 4 – Find power consumption for your PD. You’ll normally find it in the datasheet like this one:
