FMUSER N+1 Transmitter Automatic Change-Over Controller System

N+1 is a type of transmitter automatic change-over controller system that automatically switches between two or more transmitters in the event of a power outage or transmitter failure. This system works by monitoring the primary transmitter’s power output and automatically switching to the standby transmitter when the primary transmitter fails or loses power. The system will then switch back to the primary transmitter once it is back online. This system ensures that radio stations are able to remain on air even during an emergency or power failure.

It offers two modes of operation - automatic and manual. In automatic mode, the switch will detect the working status of the main transmitter and if the output power is lower than the preset main transmitter power switching threshold, the switch will control the coaxial switch and the power supply of the main and backup transmitters, automatically switching to the backup transmitter to ensure uninterrupted broadcast.

In manual mode, the panel switch can be used to select the host or backup machine to work and the switch will automatically complete the switching control of the coaxial switch and the power supply of the main and backup transmitters.

Main Features of FMUSER Auto Change-over Switching Controller

• The user can calibrate the switching threshold.
• No need for transmitter communication protocol support.
• The LCD will display real-time information about the working status of the host and backup. The coaxial switch contacts will be read in real-time to ensure the safety of the transmitter switching.
• Various states can be maintained before power failure.
• Remote monitoring of the switch can be achieved through the remote interface.
• A high-speed MCU processor is used for control, providing stable and reliable performance Two power levels are available: 1KW and below (1U), 10KW and below (3U).

What are the applications of N+1 transmitter automatic change-over controller system?

The N+1 transmitter automatic change-over controller system is a system which provides automatic protection and control of transmitters in the event of failure or maintenance. It is most commonly used in radio and television broadcasting, public address systems and other audio or communication systems. It is also used in industrial process control, for example in water and wastewater treatment plants. The main applications of the system include: 

1. Backup transmitter protection and control 
2. Load balancing of multiple transmitters 
3. Automatic selection of the best signal quality transmitter 
4. Automatic synchronization and alignment of transmitters 
5. Pre-emptive transmitter switching and protection 
6. Fault detection and alarm systems 
7. Remote monitoring and control of multiple transmitters

Why N+1 transmitter automatic change-over controller system is important for a radio station?

A N+1 transmitter automatic change-over controller system is important for a radio station because it ensures that the station has a reliable, uninterrupted broadcast. The system allows the station to switch between transmitters to ensure that the broadcast continues even if one transmitter fails or needs maintenance. This ensures that listeners can always receive the station’s signal and that the station can maintain its broadcast schedule.

How to step-by-step build up a complete N+1 transmitter automatic change-over controller system?

1. Determine the size of the system needed and the desired features
2. Select the appropriate N+1 transmitter automatic change-over controller
3. Plan the system layout and install the necessary hardware
4. Connect the controller to the primary and secondary transmitters
5. Program the controller with the desired settings
6. Connect the controller to the local network, if necessary
7. Test the system for proper operation
8. Troubleshoot and make any necessary adjustments
9. Monitor the system regularly

What consist of a complete N+1 transmitter automatic change-over controller system?

A complete N+1 transmitter automatic change-over controller system typically consists of two transmitters, a controller, and a switch. The two transmitters receive a signal from the same source, and the controller monitors their performance. If one of the transmitters fails, the controller will activate the switch, causing the signal to be routed to the other transmitter. The switch then reconnects the failed transmitter, allowing it to be serviced while the other transmitter is still in use.

How many types of N+1 transmitter automatic change-over controller system are there?

There are three types of N+1 transmitter automatic change-over controller systems:

• Manual N+1
• Automatic N+1
• Hybrid N+1

The main difference between the three systems is how they are triggered. Manual systems require someone to manually switch between transmitters, while automatic systems use a signal processor to detect a fault and then switch to the alternate transmitter. Hybrid systems combine the manual and automatic systems, allowing for manual switching but with automatic detection of a fault.

How to choose the best N+1 transmitter automatic change-over controller system for a a broadcast radio station?

Before placing a final order, you should research the different types of N+1 transmitter automatic change-over controller systems available and compare their features. Additionally, you should take into account the size of your broadcast radio station and your budget to determine which type of system is most suitable for your needs. It is also important to read reviews and feedback from customers who have previously purchased the product. Finally, you should consult with a professional in the broadcasting industry to ensure that the system you choose is compatible with your existing setup.
