Technical characteristics of SF-HC25G

The SF-HC25G plasma torch height controller is based on years of practice and several generations of related products.

• This product uses 32-bit arm as the core, two sets of 3-digit digital tube display, digital control. The linear adjustment device is not included inside, which greatly improves stability.

• The speed parameters can be modified and can be modified arbitrarily according to the power supply and lifting mechanism.

• The circuit adopts the chip technology, there is no adjustable device inside, and the full digital control technology ensures the high reliability of the product.

• Simple operation, two sets of digital tubes display the set arc pressure, and the actual arc voltage respectively, which is simple and intuitive. There are 3 knobs for setting parameter operations.

• Easy to control interface, suitable for all plasma cutting CNC systems, can also be used alone.

• Adopt the proximity positioning mode of the proximity switch.

• PWM output, 255 speed adjustable, precise control of motor speed, multi-speed current setting, short circuit protection.

• The anti-collision function of the cutting tool. When the cutting nozzle touches the steel plate, the controller will quickly lift the cutting tool a certain distance to effectively protect the cutting nozzle.

• All input and output are optoisolated. Plasma voltage feedback adopts a linear optoisolator and independent isolated power supply. It is very compatible with imported plasma power supplies of various brands with its own voltage divider.

• Integrated arc start success judgment function, arc starts success feedback function.

• Main Specifications

• Power requirements: DC24V±10%3 A/50Hz

SF-HC25G arc voltage height controller has no special port.

Four wires are required from the voltage divider of the SF-HC25G height adjuster and the plasma power connection. The two wires are at the port where the plasma starts to arc, and the plasma cutter will have it. The arc voltage signal is two lines divided into positive and negative poles. If the plasma power supply does not have a dedicated port, the plasma power supply housing needs to be opened and connected from the secondary rectification inside the plasma power supply, which is the original arc voltage of the plasma power supply.

You only need to connect the ground wire because the interference from the plasma power supply is too large. The ground wire needs to use a copper rod with a diameter of 50mm or two angle steels with a length of 2 meters. Go underground. Connect to the housing of the plasma power supply.
