Plasma Torch Height Controller Plasma THC w/ Encoder Knobs For CNC Plasma Cutting Machines SF-HC25K Technical Features:- 32-bit ARM and two 3-digit display tubes enable digital control. Without linear regulator components, its stability is dramatically improved.- Velocity and parameters can be modified according to your power supply and lifting mechanism.- Its circuit uses patch technology. There are no adjustable devices inside. Full digital control technology ensures high reliability.- Easy Operation: Two digital tubes display given arc voltage and actual arc voltage respectively. There are 3 knobs to do parameter settings and operation.- Simple Interface: It is suitable for all plasma cutting CNC systems. And it can be used alone.- Proximity switch used as initial positioning way.- PWM output and 255-level adjustable speed enables precise control of motor speed. It features several current settings and short-circuit protection.- Anti-Collision Function: When cutting nozzle touches steel plate, the controller can quickly move your cutter higher to protect the nozzle.- Excellent Compatibility: All inputs and outputs are optically isolated. Plasma voltage feedback uses linear opto-isolation and independent isolated power supply, and is compatible with various plasma power supplies.- With arcing judgment function and successful arcing feedback function.Technical Parameters:- Power Supply: DC24V10%, 3A- Compatible Motor: 24V DC motor- Drive Mode: PWM- Output Current: < Input current of power supply- Initial Positioning Method: Proximity Switch (normally open normally closed through jumper cap settings)
