Any Suggestions on Using the Dummy Load with the Transmitters?
"Whether you are a professional RF technician or a radio enthusiast, it is commonly recognized that: If you want to carry out RF tests of the FM radio transmitter without using the FM broadcast antenna, then use the RF dummy load."
-----Ray Chan, a technical employee from FMUSER
Wait, what kind of transmitter can you use a dummy load along with? Ok, this secret should never say it easily but it may be useful to you: When the power of the dummy load and the FM transmitter is similar, the bigger power the dummy load has, the more transmitter of different powers can be used, in a way, it means if you have a 2kw dummy load, you can use the transmitters with power below the 3kw (50 watt, 500 watt, 600 watt, 1kw, 2kw, etc); when you have a dummy load which power is up to 200KW, you can use dozens of FM transmitters of all kinds of ranged power
Of course, you can use the dummy load along with almost all FM broadcast transmitters of all power range, we happen to manufacture the following types of available FM radio transmitters: 500W, 600W, 700W, 1000W, 1200W, 1500W, 2000W, 2500W, 3000W, 3500W, 5000W, 6000W, 7000W, 10000W, 15000W, 20000W, 30000W, 40000W, 50000W, 60000W, 70000W, 80000W, 1000 watt, 1200 watt, 1500 watt, 2000 watt, 2500 watt, 3000 watt, 3500 watt, 5000 watt, 6000 watt, 7000 watt, 10000 watt, 15000 watt, 20000 watt, 30000 watt, 40000 watt, 50000 watt, 60000 watt, 70000 watt, 80000 watt, 1kw, 2kw, 3.5kw, 5KW, 4KW, 5.3KW, 5.4kW, 8KW, 10KW, 15KW, 18KW, 20KW, 22.5kW, 25KW, 30KW, 35KW, 40KW, 45KW, 46.4KW, 50KW, 50.7KW, 55KW, 65KW, 75KW, 80KW, 100kw, 130kw, 150kw, 230kw, 250kw, 274kw, 300kw, 500kw, 700kw, 748kw, 1000kw, 2000kw, and plenty of even higher power types of FM transmitters.
Why Choose 3KW RF Dummy Load for FM Radio Station?
You Need a Good 3kW RF Dummy Load
In addition to allowing you to accurately adjust the parameters of the transmitter and receiver, the dummy load can also prevent damage to the device caused by misoperation. Professional RF engineers all know that dummy load is a tool for loading equipment load to test on an amplifier or RF system.
If you use the antenna directly instead of any load during the test, not only can you not tune perfectly, the heat generated by RF power will directly damage your transmitter or receiver. The dummy load can be simulated the perfectly tuned antenna connected to the amplifier can avoid improper parameter setting or damage of RF equipment.
Therefore, we strongly recommend that you choose a reliable dummy load and use it timely and correctly when testing RF equipment to avoid unnecessary loss.
You can fully believe in this 3KW RF Dummy Load, just like you believe in FMUSER.
How FMUSER 3KW RF Termination Works?
In the process of RF system testing, the 1kw dummy load (also known as dummy antenna) acts as the actual "antenna". It is used to simulate the load of the electrical device, which is connected to the output of the radio transmitter. It can be used to test and configure the transmitter or receiver without radiating radio waves. A 3kw dummy load usually consists of a resistor connected to a radiator that dissipates power from the transmitter
The 3000 watt dummy load is used to dissipate RF power. It is characterized by 50 Ω impedance, and the VSWR is not more than 1.20:1. Therefore, due to the low reflection coefficient, it is very useful for :
- the maintenance of FM radio transmitter and tv transmitter
- the load discharge of the RF filter
- the end processing of the power synthesizer.
Note: The export connectors for this series of products can be replaced from the n-type fast connector to other models easily.
What You Need to Know
When the load is powered on, screw out the vent hole on the breathing valve. To eliminate, due to the increase of dummy load temperature, load chamber, heated expansion of air. If the heated air is not removed in time, the pressure in the chamber will increase, so that the pressure at the gasket is too high, and the oil leakage at the loading outlet will be caused. Enough space (at least 12 inches around and top) around the load to allow air circulation and to much more easily dissipate the heat for the dummy load

- The Fan Assembly of 3KW RF Dummy Load
When leaving the factory, the wiring of fan components has been installed, and special wiring is not required. The fan must be operated manually unless the component is connected with automatic operation in the factory. If the fan is not started, the power added to the false load shall not be higher than 1250W (suitable for 5kW and 10kW load with air cooling).
- The Transmitter Interlock of 3KW RF Dummy Load
There is an interlock between the 1 and 2 pins of three core sockets, a normally closed heat-sensitive switch (cksd301 250V 10A 60 ℃) is connected with the transmitter. If the cooling temperature of the false load is too high, the false load will be damaged, this switch will turn on and off the transmitter.
- The Maintenance of 3KW RF Dummy Load
Almost no maintenance is necessary, but it is needed to keep the machine clean and dust-proof. Field replacement of resistors is not recommended. However, if necessary, tighten the breathing valve and place the machine vertically with the RF connector facing up.
Remove the socket head screws of the 8 fixed RF components. Carefully and quickly lift the assembly so that excess oil is drained back to the radiator. Release clip at the end of the cover and remove the 6 tapered head screws. Carefully pull the cover off the resistor. To install a new resistor, follow the opposite steps, but make sure that the resistor fits perfectly with the fixture safely.
Check the O-ring between the radiator and RF assembly. If there is any crack or damage, it must be replaced immediately. After determining that the assembly is in the radiator, return to the horizontal position and check for coolant leakage.
- The Suggestions to the Cooling of 3KW RF Dummy Load
In the factory, the false load is injected at normal temperature, with a special non-toxic and non-conductive coolant, and reaches the normal plane. Observe the coolant for leaks. A small amount of leakage will not affect the work, but the leakage is large, which will have adverse effects. If there is no condition, do not replace the coolant, please use the coolant provided by the original factory. The special electrical and constant temperature characteristics of the coolant are very important for the continuous and normal working resistor.
