1. First of all, solid-state relays have a long service life and strong reliability. The solid state relay corresponds to the CDG1 series delicacy. This solid-state relay has no mechanical parts and solid-state devices to complete the contact function. Since the parts do not move, they can work in high shock and vibration environments. The performance of a solid state relay is determined due to the inherent characteristics that make up the solid state relay elements. Long service life and high reliability. The AC contactor controls the suction of the magnet through the wire rod, so that the contact contacts or disconnects, so that the contacts are burned out for a long time.
2. Solid-state relay has the advantages of high sensitivity, low control power and good electromagnetic compatibility. Solid state relays have a wide input voltage range and low drive power. It is compatible with most logic integrated circuits and requires no buffers or drivers.
3. Fast conversion of solid state relays. Solid state relays can be switched from milliseconds to subtle because of solid-state. The speed of switching is very fast. The switching speed of an AC contactor is controlled by a coil, so the switching speed is a few seconds at zero, which is slower than that of a solid state relay.
4. The electromagnetic interference of the solid-state relay is small. Because the solid state relay has no input coil, there is no contact arcing and no springback, which reduces electromagnetic interference. Most AC output solid state relays are zero-voltage switches that turn on at zero voltage and open at zero current, reducing abrupt interruptions in the current waveform and thus reducing the transient effect of the switch. The electromagnetic interference of the corresponding contactor is large.
5. The solid state relay is small in size and the contactor is large. In some places where the space is relatively narrow, it may be inconvenient to install a contactor, so a solid state relay is required; However, the current of the solid state relay is generally not very large, and the current of the contactor can be very amperes.
6. There are many kinds of voltage converters in solid-state relays, such as alternating current, alternating current, direct current, etc., but the contactor cannot be flexible.
