Specification Information Product Name: 100W 10 Ohm Rheostat with Knob Cover Precautions: Voltage Limit: Ensure that the rated AC 380V and DC 220V are not exceeded during use to avoid damaging the equipment or causing safety hazards. Adjustment Method: When adjusting the resistance value, please rotate the handle slowly and avoid fast or violent operation to ensure the normal operation of the resistor. Heat Dissipation Considerations: In high power applications, make sure the resistor has enough room to dissipate heat to prevent overheating. Installation Location: Choose a well-ventilated location for installation to ensure that the resistor can be cooled naturally during operation to prevent overheating. Regular Inspection: Regularly check the appearance and connections of the resistor to ensure no damage or corrosion and to maintain good working condition.
