Many customers rightly ask us how much energy the repeater uses. The repeater is on 24 hours a day and depending on the repeater model, the device can also get a little warm. We regularly receive questions about the power consumption of our repeaters. Fortunately, consumption is reasonable.
- 1. How do I calculate the amount of energy consumption of the repeater?
- 2. What are the electricity costs for the consumption of a mobile repeater?
1. How do I calculate the amount of energy consumption of the repeater?
The energy consumption mainly depends on the strength of the repeater. But it also depends on what components are used. The newest repeaters have the most modern parts and are therefore often a bit more economical. For example our starter-kit, the Rosenfelt RF E10S. Suitable for a coverage up to 300m2. On the adapter, it says 5Volt, 2Ampère. With this we can make the following physical calculation:
Voltage (in Volts) x Amperage (in Amps) = Power (in Watts). So 5 Volt x 2 = 10W.
2. What are the electricity costs for the consumption of a mobile repeater?
An energycompany calculates in kWh (Kilo Watt Hour). A kilowatt is 1000 watts. Multiply the power consumption in kilowatts by the time in hours. Then the consumption is 0.01 kilowatts x 24 hours = 0.024 kWh. Suppose your energy company charges € 0,22 per kWh. Then this repeater will cost you 0.024 x € 0,22 = € 0,53 per day.
We also have more powerful repeaters that can support multiple indoor antennas. These repeaters are able to service even more mobile phones. All our repeater models can amplify an unlimited number of mobile phones via the repeater at the same time. At least as many cell phones as the cell tower can handle. Another calculation example is the triband repeater Rosenfelt RF LED15-L with a coverage of 1.200 m2 or a dual band repeater Rosenfelt RF EL17-H with a coverage of 1.500 m2. Both repeaters have an adapter of 12Volt, 5 Amps. So 12x5 = 60W. Then the consumption is 0,06 kilowatts x 24 hours = 0.317 kWh. Cost price per kWh is € 0,22. Then this repeater will cost you 0.317 x € 0,22 = € 1,67 per day.
Our absolute top model, the Rosenfelt RF20-5B, is suitable for a maximum of 8 indoor antennas and an area of up to 2.000 m2 has almost the same consumption.
