Features: 1. Automatic Voltage Regulation: Eliminate feed speed variation caused by mains voltage fluctuation . 2. Soft Startup: In order to avoid sudden shock to the feed material and vibratory feeder, the controller can gently increase output voltage from 0 to the preset value when startup. 3. Linear Voltage Control: Rotation angle of the voltage adjustment knob is linear with output voltage of the controller 4. Overheat Protection: If internal temperature of the controller gets too high. the controller will stop its output to protect itself. 5. Overcurrent Protection: If output current exceeds its rated value by misoperation, the controller will stop its output to protect the controller and vibratory feeder 6. Short-Circuit Protection: If output of the controller is short-circuited. the fuse inside the controller will be blown to protect the controller and vibratory feeder from further damage. Dimensions: 102’63227(L’VPH. mm) Weight: The controller weights 92g without accessory
