Products Feature： Simplification of the three-phase connection. Inspection of over-current, unusual-current. SCR over heat. Trake & control several ” Parallel controllers ”. Constant torque / HP. Low breakdown / Easy maintain. High efficiency of speed cintrol, complete protection system. High precision / wile speed(100:1) / add function is available. 2Q type - single direction. (Normal speed control) 4Q type - all electroic control. (Forward. Reverse. Brake.) NEXT Back List Inquiry , Product Description Product Dimension 【Control Principle】 This controller uses thyristor six phase bridge rectifier(input:AC output : DC) The voltage is changed by pulse. it constants the speed within different DC voltage. (一)4Q feature (Forward / Reverse instant) Single type: (AC 200-400V) Easy connection Inspection of over-current, unusual-current, over heat. Unusual magnetic. Voltage feedback built-in. Detachable terminal. (二)DM 4Q control principle This controller uses two SCR bridge rectifier and reverse parallel. The motor is forward when SCR1 is on. The SCR2 will transmitting electricity and it brake. when the SCR1 is off. The motor is reverse when SCR2 is on. the SCR1 will transmitting electricity and it brake. when the SCR2 is off. (三)Precautions & Temperature Reserve GAP when installing the controller. The control box needs vents or fan. Dont over 70% of capacity if the enviroment is too hot. Dont install the controller in moist / dusty / gases place. Moisture:less than 90% RH. Temperature: -10°C~45°C
