RX20 Adjustable Wirewound Power Resistor
RX20 adjustable wirewound power resistor is a high-power variable wirewound resistor manufactured by Guangdong Qingda Electronic Technology Co., Ltd. Wound with premium high-temperature alloy resistance wire on high-temperature resistant ceramic tube base, it adopts sliding contact tap structure to realize continuous resistance setting within rated range.
Different from fixed resistors, RX20 allows on-site resistance tuning to meet variable load requirements. The ceramic substrate provides excellent insulation and heat resistance. It can withstand instantaneous pulse overload and maintain stable resistance during long-time heavy load operation. Protective coating guards the winding wire against moisture, dust and oxidation. With simple mechanical installation structure, it is easy to mount on control cabinets and test benches.
