20W High Power Adjustable Resistance Box, Precision Variable Resistor Load Bank Electronic Experiment Teaching Test Equipment

20W High Power Adjustable Resistance Box, Precision Variable Resistor Load Bank Electronic Experiment Teaching Test EquipmentSpecifications: Resistance Accuracy: 5% Range Gears: X1, X10, X100, X1K, X10K, X100K Number of Gears: 6 gears Steps per Gear: 0–9 Adjustment Step Value: 1Ω Adjustment Range: 0–999.999KΩ Direct Short Resistance at 0 Position: <0.4Ω Power: 20W Product Dimensions: 160 x 100 x 106 mm Notes: The knobs are mechanical switches. When adjusting gears, the mechanism operates on a break-before-make principle. A slight rotational gap is normal during operation. Please adjust the gears gently to avoid excessive force that may damage the gear switch and affect measurement accuracy. Before connecting wires, ensure there is no residual voltage to prevent short circuits or damage to the device. Avoid dropping, bumping, or exposing the device to corrosive substances. Store in a dry, well-ventilated environment to extend its service life. Package included: 1 x Variable Resistance Box
