10kW Sliding Variable Power Rheostats,Asynchronous Adjustable
Structure :
1.Beautiful Appearance,multifunctional configuration,high accuracy
adjustment ,safe & convenient for use.
2.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.
3.DS series resistor,realize continuous adjustment,step values can
be adjusted according to customer requirements.
4.High power,shock resistance,fast heat dissipation,high
stability,long life & fast delivery .
Features:
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,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.
