» SSR-25DA ssr solid state relay DC-AC one-phase Relay FOTEK ssr 20A minitype
Solid state relay ( SSR ), belongs to electronic contactless switch.The main characteristics are:small control signal input, directly driving high current load. It is widely used,for example, used together with temperature control instrument, can quickly control the electric heaters.
long service life,contactless,no spark,no noise,no electromagnetic interference,fast switching speed,strong anti-interference capability,reliable work, and has the advantages of small volume, vibration resistance, explosion prevention, corrosion prevention, compatible with such integrated circuit as TTL, DTL, HTL and so on. .
Output contact is not so much as contactor,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 control 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 selection current size,pay attention to heat dissipation when current is above 5A!
