Solid state relay failure has a variety of reasons. In most cases, ineffective means cannot be switched on or off. In general, solid state relay failure is due to incorrect installation, because they are simple and reliable. If your solid state relay failure, first check the operating parameters of solid state relay and ensure the solid state relay is suitable for the system, and solid state relay installed correctly. The common cause leading to the invalid SSR) has the following three: 1, the solid state relay and load does not match. Due to the large load current for a long time, solid state relay overheating damage. 2, solid state relay protection inadequate. Remember than simple metal contact solid semiconductor. The phase voltage exceeds the level of PRV solid state relay, will cause damage. Switching circuit of the voltage spike, may be the influence of inductance, destruction of one or more of the internal switch equipment. Large inductance load, remember to use shock absorber, diode, MOV, or rectifier diode. 3, solid state relay installation is not correct. Solid state relay is not installed radiator, big enough or not using heat transfer element, makes the solid state relay is overheating. Load without fastening good, also will produce a solid state relay electric arc or fever. Recommended in the threaded end of the load torque is 15 to 16 inch - 英镑。 To ensure that the terminal clamp, and carries on the welding seams in, ensure good electrical contact, and protection against corrosion. Solid state relay true experts, in order to your satisfaction, we really heart. If interested in our solid state relay or there is doubt, welcome your consultation.
