Rele Estado Sólido Foteh Ssr-40 40a

Solid state relay ( SSR ), belongs to electronic contactless switch.The main characteristics are:small controle signal input, directly driving high current load. It is widely used,for example, used together with temperature control instrument, can quickly controle the electric heaters.


Advantages:long service life,finalmente,não spark,não noise,não electromagnetic interference,fast switching speed,forte anti-interferência capability,reliable work, and has the advantages of pequeno volume, vibration resistance, explosion prevention, corrosion prevention, compatível with such integrated circuit as TTL, DTL, HTL and so on. .

The main insufficiency is: output contact is not so much as contator,only one group; in addition,due to pressure, temperature rises quickly if the load is above 5A.So you must pay attention to heat dissipation.You can also use special solid state heat sink.


Attention of first use:this product can only controle the resistive electrical appliances, like a series of electrical heating appliances as electric wire, electric heating pipe,and there must leave 3/2 margin of the current selection size,pay attention to heat dissipation when current is above 5A!
