The sliding rheostat can change the resistances of the connected circuit and act as a continuous change of current size, but can not know the resistance value of the connected circuit accurately.If you need to know the resistance of the connected circuit, the resistance box will be used.
Resistance box is a rheostat that can adjust resistances and can display resistance resistance.
It is compared with a sliding rheostat, and a sliding rheostat cannot represent the resistance of a connected circuit, but it can change the resistance in the access circuit continuously.The resistance box can indicate the resistance value of the connected circuit, but the resistance change is discontinuous and there is no sliding rheostat.
Tower crane Hoist Resistance Box RW4F-225M-4 / 8-3Y / 24 / 24KW. RW4F-250M-4 / 8-4Y / 30 / 30KW. RW4F-250L-4 / 8-5Y / 37 / 37KW. Applicable to AC 50HZ voltage to 500V and DC voltage 440V circuit, mainly as a motor starting, braking and speed control.
Factory dedicated data. Three-stage resistors R1, R2, R3. Up 1 speed, 2 steps: eddy current brake speed. Up 2 files then cut off a resistor. Up 3 files: Cut the vortex. Then delay 2 seconds, remove all two resistors. 4 files cage system. Two - speed motor. 1,2,3 files, 8 very low speed. 4 files, with 4 pole high speed. Low speed to high speed, converter HKJ closed use.
24 / 24KW, 30 / 30KW, 37 / 37KW tower crane dedicated resistance box, from the economic security and other considerations, has its wide range of applications
