1【Product Description】: This product is a single-phase DC solid-state relay module, SSR-40DD Input 3-32V DC to Output 5-220VDC 40A, length, width and height are 62.6 mm * 45.3 mm * 23 mm, weighing0.16 lb respectively
2.【Outstanding advantages】: The solid-state relay can accurately control the disconnection of the heating elements, and achieve accurate temperature regulation and constant temperature control, so as to improve the efficiency and comfort of the heating system.
3.【Widely used】: The dc solid state relay 40a has the characteristics of no mechanical contact, no arc, and can meet the special needs of the chemical industry, coal mining and other industries.
4.【Note】: The Single Phase SSR-40DD Switch is very useful. When the 40 amp solid state relay is open and there is a voltage at the load end, there will be a certain leakage current at the output end. Care should be taken to prevent when using or designing.
5.【 Photoelectric coupling technology】 Solid-state relay photoelectric coupler realizes the electrical isolation between the input circuit and the output circuit. It can effectively block the electrical connection between circuits or systems, but does not cut off the signal transmission, thus improving the safety and stability of the system
