Scope of application: less than 750W DC permanent magnet, excitation motor motor universalinput voltage: AC 110V-220V 50/60Hzoutput : 750W when AC 220V input; 300W when AC 110V inputexcitation voltage: when AC220V input, excitation terminal L+ L- is DC 205VDCWhen the AC 110V is input, the excitation terminal L+ L- is DC 95VDC.armature voltage: When AC220V input, the armature end M+M- is arbitrarily adjustable from 0-220VDCWhen AC110V is input, the armature terminal M+M- is arbitrarily adjustable for DC 0-110VDC.potentiometer matching value: 4.7Kohm 2Wthe terminal is marked as K: character K two terminals, is the start and stop switch, no need to try direct wire connectionthe wiring is used:1, permanent magnet DC motor motor (motor lead wire is 2 lines):Controller, M+M- is connected to the motor; at this time, L+L- is empty, remember not to connect any other line.2, excitation DC motor motor (motor lead wire is 4 wires):Controller, M+M- is connected to the motor armature; L+ L- is connected to the motor excitation. Note that the two are not reversed.Colour:greenMaterial:plasticSize:100 x 75mm Package Contents:1 x drive module(Some accessories:random colors, don't accept the specified color)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
