Power Consumption of Power Injector

Hi,

Hope you can assist me. My customer requested me to calculate the power consumption required for the installation of one unit of AP 1510 using the following power injector, part no: Power Injector (AIR-PWRINJ1500). He would like to know the cost required so that the building management can include the necessary cost of the implementation of the device.

From my initial research, I notice the following input power requirement

Power Injector

Input: 100-240V ~ 1.5A (300Watt)

Output: 48V ~ 1.2A (58Watt)

Power consumption: 240*1.5 = 360 W = 0.36KW

Assuming cost per unit is 0.39 cent

Amount required per hour = 0.36*0.39 = 0.14 cent

Amount required per day = 0.14*24 = 3.36 dollar

Is my calculation correct?

Thanks.

Delon
