Solenoid coil 110VAC for HKDHE AC

In case of AC coils the power input is significantly higher in the considerably phase than in the holding phase. These must therefore never be operated without a magnet core since there is a danger of overheating and the coil can burn through. A similar effect occurs if valves with AC magnets are operated with extremely high pulse frequencies (On / Off). In such cases the coils, which are often in the vicinity of the high power input, can also overheat. For such applications the use of RC coils with rectifier plugs is recommended.With DC coils extremely high power spikes can occur during powering down. We therefore recommend the use of plugs with protective circuits when using such coils.Tightening torque for attaching nuts of the solenoid coils: 3NmPlease use rectifier plug HK SP 669 for solenoid coils type RC.
