Adjustable Resistance Box Precision Large Power Adjustable Resistor Boxes Rectifier Modules Test Machine
Introduction
Adjustable resistance boxes are mainly used in AC and DC circuits where the resistance value needs to be adjusted to change the working current, voltage, or set a certain fixed resistance value. In low-current applications, a single sliding variable resistor is commonly used to achieve this. However, in high-current applications, special alloy resistance materials are needed to form multiple high-power resistors for effective combination and use. These products are also commonly applied in power generation equipment and the excitation and speed regulation of DC motors.
It is manufactured by using high-quality large-power resistors independently developed by Lonroy and various new alloy resistors. The product features multiple adjustment functions and control methods for selection. The data can be displayed in real time, enabling easy completion of various AC power and DC power adjustment needs as well as loading detection requirements for DC motors, DC generators, rectifier modules, etc. The product includes large-power adjustable resistor boxes, precision adjustable resistor boxes, adjustable load resistor boxes, adjustable AC resistor boxes, adjustable DC resistor boxes and adjustable non-inductive resistor boxes, etc. It has the advantages of high adjustment accuracy, wide adjustment range, safe operation, stable and reliable performance.
