1. When the long-term working current is ≥5A, it must be installed with a matching radiator. The temperature of the radiator bottom plate must not exceed 80°C. If the ambient temperature is too high, air cooling must be used to accelerate the air flow for better heat dissipation.
2. To ensure that the solid state relay is in close contact with the surface of the heat sink during installation to achieve a better heat dissipation effect, please place the heat transfer film in parallel between the solid state relay chassis and the heat sink contact surface and tighten the mounting fixing screws during installation; When installing thermal grease, apply a proper amount of thermal grease to the solid state relay board and tighten the mounting screws.
3. To prevent breakdown damage of solid state relays caused by load short-circuit or over-current or voltage overload operation, it is recommended to install and use special fast fuses that match them. For inductive loads, it is also necessary to install varistors and RC absorption loops at the solid-state output terminals. For DC solid-state relays, inductive loads must be installed with freewheeling diodes.
4. The solid state relay must ensure that it has enough and does not exceed the nominal trigger voltage and current value. For example, the control terminal is "3-32VDC", that is, the minimum input voltage must not be less than 3VDC, and the maximum must not exceed 32VDC. Therefore, special attention must be paid to meet the triggering requirements of solid state relays in series or parallel use.
5. The storage of solid state relays requires moisture protection, moisture protection, rain protection, drop and severe impact. Should be stored in a ventilated, dry, non-corrosive atmosphere. The humidity of the environment must be less than 80%.
