Portable Type Variable Power Resistors Load Bank Controlled By Handle Wheel
Structure :
1.Beautiful Appearance,Multifunctional Configuration,High Accuracy
Adjustment ,safe & convenient for use.
2.BC1 series Variable Rheostat is wound with copper or
chromium-alloy wire as a resistance element. Except for the slide
contact surface,the entire component is coated with a
high-temperature,non-flammable resin. After cooling and drying,
insulation is applied through a high-temperature process.Then,a
centered rotating adjuster component is installed,which slides
along the resistance element and varies the resistance to the
desired value.
Features:
1.BC1 series Variable Rheostats called varistors or potentiometers. Used as two connections terminals of varistors or as a potentiometer with three connection terminals. When single rheostat cannot meet its power, which can be increased by connection of multiple rheostats, max up to 6 connected rheostats.
2.On the basis of 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.
