IP56 Protection Adjustable Resistance Box with 220V Voltage and 0-1500V Range for Precision Large Power Applications

Adjustable resistance boxes are essential components in AC and DC circuits where precise resistance value adjustment is required to modify working current, voltage, or establish specific fixed resistance values. These units are particularly valuable in high-current applications where special alloy resistance materials are necessary to form multiple high-power resistors for effective combination and use.
