HYD THC Arc voltage torch height controller XPTHC-4H
Application
XPTHC-4H supports almost all plasma cutters on market like Hypertherm, Thermal Dynamics…
And it supports all CNC cutting controllers on market like Hypertherm, Burny industrial level controllers or Mach3 such DIY controllers, because XPTHC-4H can start Auto Height control with or without Auto enable signal from CNC. But with Auto enable/disable signal from CNC, THC would work better.
Basic Parameter and Feature
Input Power：AC24V+10%，50Hz/60Hz or DC24V±20%;
Motor：DC24V DC motor;
Motor Drive：PWM;
Output current：0.1A-1.8A;
Load capacity：Max 20W；
Working temperature：-10∽60℃；
IHS：Switch IHS & Proximity switch IHS； Do Not support the retaining cap HIS
Work way: check the arc enable output, 200mA optical coupler OC door output
Voltage Divider ratio: 50:1 non-isolation on voltage divider; 1:1 isolation inside of THC
Control accuracy ：±1V∽±3V，depends on the motor and lifter of user.
The speed of lifting：1000mm/min ∽ 3000mm/min(Contact the supplier if it exceeds the range of speed）；
Arc Voltage rang：50V∽250V，
Over protection：PWM adjusting, current feedback；
Max speed test：12000mm/min（ it’s related to the setting on the lifter’s speed and motor’s start voltage and sensitivity)
XPTHC-4H is the newest design THC, special for portable CNC cutting machine and small bench type machine, with 32 ARM processors, and analogous circuit height control together.
Feature:
1, installation: user could install the THC’s operation panel on the work interface, or install it at the convenient operation place. Install the main body at a suitable station.
2, height controller: could change the auto cutting height at any time
3, two modes of the setting arc volt:
A, Setting arc volt mode: set the setting arc volt on the operation panel, let the THC work on the setting arc volt status. It’s the traditional work way.
B, sampling arc volt is the setting arc volt: when the THC control the torch finish the HIS and plasma start, and CNC controller open the AUTO signal to THC, and THC will test the arc value as the setting arc when at beginning the AUTO status. It’s suitable for some small plasma.
4, High Sensitivity: adjusting the THC’s sensitivity, could realize the arc volt change 1V, the arc voltage output will change 1.5V~4V, and don’t occur the vibration. So the lifter’s start voltage is closed related to the THC’s sensitivity, Our lifter’s start voltage is 1.5V ~2V.
6, Good stable: XPTHC-4H has 5 sets isolation power inside, to realize the I/O isolation; sampling arc volt isolation; drive isolation; and control isolation.
XPTHC-4H is with full functions of the Stand alone Arc Voltage Torch Height Controller. But as it’s with small body, the motor of the lifter should be less than 20W on the portable CNC cutting machine, light gantry machine and small bench type machine etc.
