How many watts of power supply does the transmitter use? What is the relationship between power and power consumption?

How many watts of power supplies can the transmitter use? Do you know the relationship between power and power consumption and power consumption?


How much is the power consumption of the FM transmitter calculated?
FM transmitter efficiency is 70%
Power /70% = power consumption


The TV transmitter is calculated like this, for example a 2KW TV transmitter
The analog 2KW transmitter is generally multiplied by 1.7 coefficient, 2*1.7=3.4KW. This is the actual power used. Considering that there must be a margin, because in addition to the amplifier and other devices such as modulators, it is generally used 4kw- 5KW power supply, and there is no 3.5KW power supply on the market.


The power consumed by the digital TV transmitter is generally multiplied by 6 coefficients, 2KW * 6 = 1.2KW ,, 50W *6 = 300W power supply
(The power consumed by digital TV transmitters is generally 3 to 4 times that of analog, 50W digital TV is equivalent to 200W of analog TV, and the efficiency of output power is about 65~70%)
The power supply on the market is generally 1KW, 3KW, 4.5KW, 5KW.


If you need to buy a high-powered power supply, you need to distinguish between 220v, 110v or 380v. The 380v uses three-phase power.
