Product selection guidelines:

When selecting our product, it is important to consider the nature of the load and leave appropriate margins for current and voltage levels. For resistive loads, choose the current based on 2-4 times the load current and the voltage based on 2-3 times the load voltage. For inductive or capacitive loads, select the current based on 4-8 times the load current and the voltage based on 4-5 times the load voltage.

To ensure optimal performance, take into account the relationship between the load current and ambient temperature. If the ambient temperature is high or the heat dissipation conditions are poor, it is recommended to increase the current capacity. To prevent short circuits in the load circuit during use, it is essential to include a fast circuit breaker or a fast fuse in the load circuit.

When dealing with inductive loads, it is crucial to include a freewheeling diode in parallel with the load or a voltage-dependent resistor and RC absorption circuit at the output end to prevent damage to the transistor from over-voltage. The voltage-dependent resistor (MOV) should be selected according to 1-2 times the power supply voltage, and the RC value should be selected according to the load power.

During installation, make sure that the contact surface between the heat sink and the product is flat and smooth. Apply a layer of thermal grease to its surface to optimize heat dissipation. Finally, tighten the screw with a flat washer and a spring washer symmetrically to secure it in place. We hope these guidelines help you to make the best use of our product.
