Model: SH-HC30 Designer, Researcher and Manufacturer, Supplier's Supplier Advanced Technology, Excellent Quality Reasonable Price, Thoughtful Service Easy Operation, Powerful Functions Customise according to Your Requests Technical Parameters: Power Requirements: DC 24V +- 2 V 3 A Applicable motor: 17/23 hs series of stepper motors Manual adjustment range: 0-100 mm Automatic height control range: 3 -30 mmu Adjusting speed of automatic height control: 3000 mm/min (30degree slope) Control precision: +-0.5 mm Dimensions of box body: (155 X 87 X 71) mm Operating temperature: -10 C to 50 C Technical Features: Torch height controller for flame/plasma cutting torch uses the proprietary stepper motor control technology of Microstep to replace the conventional DC motor height control technology, which makes it faster and smoother in addition to significantly entended service life. Directly displaying the height of cutting nozzle in capacitance height control mode The advanced height linear calibration technology makes absolute height display and control possible when the distance between the cutting nozzle and work piece is within 3 30mm in the capacitance mode under for automatic height control in step of milimeter and display accuracy of +-0.1mm. Integration of mechanical lifting device and height controller Detector, controller and drive are highly integrated with adjustable stroke up to 10cm. All Digital Technology Circuit uses SMD technology without any adjustable devices; all digital control technology ensures high product reliability. Simple and convenient linearization calibration The feature of "one-keystroke height calibration" guarantees that in any circumstances, the user only needs to press one key to calibrate the absolute height measurement and achieve linear height measurement. Applicability in tough environment The shell uses tamper-proof, waterproof and moisture-proof aluminum box sealed design, particularly applicable to the severe environment of high temperature or high electromagnetic interference from flame cutting or plasma cutting operation. Various interfaces easy to use.
