Digital TV integrated machine has the following advantages:
1. The quality of signal processing and transmission depends on the source.
2. It is easy to realize the storage of signals, and the storage time has nothing to do with the characteristics of the signal.
3, digital television using data compression technology.
4. Digital technology can realize multiple time divisions and make full use of channel capacity.
5. The digital television signal after compression is digitally modulated and can be broadcast in various forms.
6, is open and compatible.
7. Various types of spectrum resources can be reasonably used.
8. In a synchronous transfer mode (STM) communication network, a "dynamic combination" of multiple services can be realized.
9. It is easy to implement cryptographic measures, namely encryption/decryption and addition/interference, which facilitate the application of professional applications (including military applications) and data broadcasting services.
10. With scalability, separability, and interoperability, it is easy to communicate in various types of communication channels, especially asynchronous transfer mode (ATM) networks, and it is also easy to communicate with computer networks.
11. Change the way people accept television.
12. The emergence of digital television will also greatly change the market structure of information appliances.
Thermal Overload Relays are protective devices used for overload protection of electric motors or other electrical equipment and electrical circuits,It consists of heating elements, bimetals,contacts and a set of transmission and adjustment mechanisms.
Our Thermal Overload Relays had been divided into five series(as follow),with good quality and most competitive price,had exported into global market for many years:
LR1-D New Thermal Relay
LR2-D Thermal Relay
LR-D New Thermal Relay
LR9-F Thermal Relay
Intermediate Relay
The working principle of the thermal relay is that the current flowing into the heating element generates heat, and the bimetal having different expansion coefficients is deformed. When the deformation reaches a certain distance, the link is pushed to break the control circuit, thereby making the contactor Loss of power, the main circuit is disconnected, to achieve overload protection of the motor.
As an overload protection component of the motor, the thermal relay has been widely used in production due to its small size, simple structure and low cost.
