Delixi solid state relay and Delixi communication contactor are more used products, so what are the advantages of solid state relay relative to communication contactor, how should we choose when we can choose?
1. First of all, the solid state relay has a long life and strong reliability. SSR solid state relay corresponding to Delixi is CDG1 series, this solid state relay has no mechanical parts, there is a solid device end contact function, because there is no movement of parts, so it can work in a high impact, oscillating environment, due to the inherent characteristics of the components that make up the solid state relay, determines the long life of the solid state relay, high reliability. The communication contactor is to control the magnet through the coil to make the contact contact or disconnection, which will cause poor contact contact and other problems to burn the contactor after a long time.
2. The solid-state relay has good sensitivity, small control power and good electromagnetic compatibility. Solid state relays have a wide input voltage range, low drive power, and are compatible with most logic integrated circuits without the need for buffers or drivers.
3. Rapid conversion of solid-state relays. Due to the use of solids, the switching speed of solid-state relays can be from a few milliseconds to a few subtleties, and the conversion speed is very fast; The engagement of the communication contactor is controlled by a coil, so the conversion speed is in a few tenths of a second, which is slower than that of a solid state relay.
4. The electromagnetic interference of the solid-state relay is small. Since the solid state relay has no input coil, no touch arcing and no bounce, electromagnetic interference is reduced. Most AC output solid state relays are a zero-voltage switch that turns on at zero voltage and turns off at zero current, reducing abrupt aborts of the current waveform and thus reducing switching transient effects. The electromagnetic interference of the corresponding contactor is larger.
5. Solid state relays are smaller in size, while contactors are large in size. In some places where the space is relatively narrow, it may not be very convenient to install the contactor, so the solid state relay is required; However, the current of the solid state relay is generally not very large, while the contactor current can be very large.
6. There are various varieties of voltage conversion of solid-state relays, such as communication to communication, communication to DC, DC to DC, etc.; Contactors are not so sensitive and changeable.

The operating structure of the high-voltage circuit breaker - Delixi
1. Classification of switch operation organization
At present, the switches we encounter are generally divided into many types, such as oil-rich type (old model, now you can't see it at all), oil-poor type (some user stations also have it), SF6, vacuum, GIS (combined electrical appliances) and so on. These are all about the arc extinguishing medium of the switch. ...

Delixi voltage regulator working principle
In Delixi voltage regulator, the voltage correction from and under voltage conditions is performed through two basic operations, namely Oersted and step-down operation. These operations can be switched on and off manually or automatically by electronic circuits. Under voltage conditions, the voltage of the boost operation is increased to the rated voltage.
