Resistive Sliding Variable Power Resistor Rheostats Box With Handle Wheel


Resistive Variable Power Sliding Rheostats Box,with 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.


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,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.
