The two terminals in the three -phase solid -state relay are the input control terminal, and the other ends are output controlles. The three -phase are six ends, three in three in three outs, and areolate in the middle.Add DC or pulse signals to the input terminal, and the output end can be transformed from the control state to the directional state (there is no signal to be blocked), so as to control a large load.
Three -phase solid -state relay price
Three -phase solid -state relay brand
It is better to do Simanton, Xizi, Xinjia, and Sanying in China.(1): The only concept of Higmanton is that he is DBC, which is good for heat dissipation, but his chip uses domestically produced, and the heat dissipation is not very good.(2): Xizi solid -state relay, the internal process of the product is not good, but the use is better, imported silicon chip, but the price is expensive, if the large current can be used, small current is unnecessary.(3): New best product technology and silicon are mostly domestically produced, and the price is also expensive. Generally, it is similar to that of Nishiko and Hermann.(4): The Sanying Solid -state relay is relatively young, the product awareness is not high, but the welding technology is more prominent, the high -pressure indicator is high, the reputation is not bad, and the development prospects are quite large.
Three -phase solid state relay principle
The three -phase solid -state relay (abbreviated SSR) is a non -touch point switch composed of microelectronics, separated electronic devices, and power electronic power devices;The four -terminal device of the end uses an isolation device to achieve electrical isolation input and output.The input terminal of the solid relay uses a small control signal to achieve a direct drive large current load.
Three -phase solid state relay wiring
Note: ● When selecting the product, you should leave different balances in the current level according to the nature of the load.(When obstructing load, you can choose more than 2 times the load current. When the sensual or capacity load, you can choose more than 3 times the load current).● According to the relationship between load current and ambient temperature, when the environmental temperature is high or the heat dissipation conditions are not good.The current should be increased.In order to prevent short circuits during use, it is required to connect the fast circuit switch or fast fuse corresponding to the product in the load circuit.● When the perceptual load, the sensitive resistance should be pressed at the output end to prevent damage to the crystal tube when over pressure.Optional of the pressure-sensitive resistance (MOV): 430-470V is selected at 240V files, 680-750V is selected at 440V files, and 1100-1200V is selected when the 660V file is selected.● When installing, it is required that the contact surface of the heat sink must be flat and smooth, and evenly apply a layer of thermal silicon grease on its surface, and finally tighten the screws of the flat pads and spring pads.
