High voltage ac switching solid state relay

  • Optical magnetic isolation between input and output circuits.
  • Light Emitting Diode (LED) indicates working status.
  • A set of normally open solid-state, contactless switch outputs, switching without sparks or arcing.
  • The highest output withstand voltage in both forward and reverse directions is above 2400V.
  • Epoxy resin encapsulated as a whole, shockproof and corrosion-resistant, stable and reliable operation. The product is mainly used for high voltage, high current, and high power load electrical equipment.

Notes while using
  • When selecting a product, different current margins should be left according to the different nature of the load. (For resistive loads, select 2-3 times the load current. For inductive or capacitive loads, select 3-4 times the load current).
  • Based on the relationship between load current and ambient temperature, when the ambient temperature is high or the heat dissipation conditions are poor, the current capacity should be increased and the size of the heat sink should be enlarged. To prevent load short circuits during use, it is required to connect a corresponding quick-break switch or fast fuse in series with the load circuit.
  • For inductive (capacitive) loads, a varistor should be connected in parallel at the output end to prevent high voltages caused by high-order harmonics from damaging the solid-state switch. Selection of Metal Oxide Varistor (MOV): choose 1200-1500V for the 660V range. An AC overvoltage protection absorber produced by our factory can also be equipped.
  • During installation, it is required that the contact surface between the heat sink and this product must be flat and smooth, and a layer of thermal conductive silicone grease should be applied to its surface. Finally, screws fitted with flat washers and spring washers should be symmetrically tightened and secured.
