5000W Model High Power Slide Wirewound Variable Load Resistors
Structure :
1.DS Series resistor,high temperature resistance ceramic tube used as the resistance matrix,is wound with chrominum alloy wire,then coated with high temperature &non-flammable resin for protection to let resistors with better appearance and heat dissipation effect,after natural drying,baking at different temperatures before assembly.
2.DS series resistor,realize continuous adjustment,step values can be adjusted according to customer requirements.
3.Single resistor can be made into load bank,or multiple resistors can be combined in series and parallel to an adjustable load bank, so as to realize high-power adjustment and meet the voltage and current parameters,which is also flexible and convenient.
Features:
1.DS series resistors are the most high-end in terms of material sele ction and workmanship compared to other adjustable resistors,so they are deeply recognized by users. According to the needs of users, the resistor can be equipped with temperature control device and digital scale.
DS Series high-power adjustable resistor is upgraded from DR series high-power wirewound resistor, and its resistance value can be adjusted manually to meet the needs of the circuit.
Due to different application occasions,high-power adjustable resistor is also known as sliding rod resistor,sliding wire resistor, sliding wire rheostat,hand-push adjustable resistor, hand-swing adjustable resistor and so on.
DS series resistors are the most high-end in terms of material selection and workmanship compared to other adjustable resistors,so they are deeply recognized by users.
According to the needs of users, the resistor can be equipped with temperature control device and digital scale.
