200V-500V,Variable Power Load Banks Controlled By Handle Wheel
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.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.
4.On the basis of DST / DSY/BCI 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,which 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.
Features:
1.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.
2.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.
3.According to the needs of users, the resistor can be equipped
with temperature control device and digital scale.
