Family of fast, hybrid relays SHR is designed for use in all types of circuits DC and AC.
It combines the best features of electromechanical relays – minimal contacts resistance and modern semiconductors components high speed. Additional feature of switching off high currents in circuits which include inductive components predisposes them for professional use.
SHR relays output contacts could be connected in any way, also with different types of relays. With serial connection, operating voltage and maximal switching power increases with number of serial connected contacts.
Parallel connection provides n-times current and switched power increase if serial resistors are used. Every hybrid contact is made up of a solid state contact and a normally open contact of electromechanical relay. Hybrid contacts have reliability twice as high as traditional relays, reed contacts or semiconductor contacts.
In addition, hybrid contacts are provided with an individual optical indication of activation and continuity of external circuits (option).
Currently manufactured relays are designed to switching currents 3A-16A with contact voltage 250V-1kV and control voltage 12V-220V DC
Attention! On request there are available the hybrid and auxiliary contacts in any configurations.
