Structure :
1.Beautiful Appearance,Multifunctional Configuration,High Accuracy Adjustment ,safe & convenient for use.
2.DS series resistor,realize continuous adjustment,step values can be adjusted according to customer requirements.
3.High power,shock resistance,fast heat dissipation,high stability,long life & fast delivery .
4.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.
Features:
1.On the basis of DST / DSY sharp, the resistors can be equipped with temperature control device,for safety,beauty and convenience,we recommend that it should be made into the form of load bank.
2.They can realize the installation of heat dissipation fan,temperature control protection,overcurrent and overvoltage protection, alarm device,multifunctional digital display (digital display of power,resistance,current,voltage, frequency, etc.) and single unit with AC and DC dual-purpose functions.
