The plate-type adjustable resistor is a high-power adjustable resistor that uses constantan or nichrome alloy wire as the resistive element. Its casing is constructed of a high-strength insulating ceramic plate, providing excellent heat dissipation and mechanical strength. The resistance value can be continuously adjusted by moving the sliding contact point, achieving stable voltage and current control.

This product features a robust design, excellent high-temperature resistance and overload resistance, enabling stable operation over extended periods. It is widely used in experimental equipment, motor speed control, power supply regulation, and load testing.

• High Heat Resistance, Stable and Reliable The resistance wire is wound with high-temperature alloy material and uniformly coated on a heat-resistant ceramic substrate, providing excellent heat dissipation and temperature stability.
• Precise Adjustment, Convenient Operation The resistance value can be continuously adjusted via a sliding contact. The adjustment process is smooth and sensitive, meeting the needs of precise current control in laboratory and industrial testing.
• Superior Overload Capacity The resistor can withstand instantaneous high current surges, possessing excellent overload resistance and durability, ensuring long-term reliable operation.

Plate-plate adjustable resistors are widely used in experimental teaching equipment, motor speed control systems, DC power supply testing, charging and discharging devices, current distribution control, experimental load test benches, and transformer equipment and other fields. Its flexible adjustable characteristics and high power carrying capacity make it an ideal current and voltage regulation element in industrial control and scientific research experiments.
