Selection tips

The data in the parameter table is measured at room temperature (25°C). In actual operation, a margin should be allowed. For resistive loads: select the current at 3-4 times the load current and the voltage at 2-3 times. For inductive loads: select the current at 4-6 times and the voltage at 4-5 times.

 

When the ambient temperature is high or the cooling conditions are poor, the current rating should be increased and the size of the heatsink should be enlarged. To prevent overcurrent or short circuit in the load during use, a fast circuit breaker or fast fuse should be added to the main circuit.

 

For inductive loads, be sure to connect a freewheeling diode across the load or connect a varistor and RC snubber circuit at the output to prevent transistor damage due to overvoltage. The varistor (MOV) should be selected at 1-2 times the power supply voltage, and the RC value should be selected according to the load power.

 

During installation, the contact surface between the heatsink and this product must be flat and smooth, and a layer of thermal grease should be applied to its surface. Finally, tighten the screws with flat washers and spring washers symmetrically to fix them.

Product Details
 

The weak current part and the strong current part are optically and magnetically isolated.
Transistor PWM output, with output power adjustable over a wide range.
Contactless output, no sparks or mechanical wear during operation, resulting in a longer lifespan.
Built-in overvoltage absorption protection to prevent transient high voltage from breaking down the solid-state switch.
Solid encapsulation, shockproof, corrosion-resistant, stable and reliable operation.
Mainly used for power regulation of heating appliances powered by DC in new energy vehicles, motor speed control, and lighting dimming functions.
