Technical Features
One-touch dual electrostatic charging mode switching system; patented “automatic regional power control” and constant-current spraying.
Patented controllable minimum holding power technology — designed for complex deep-groove powder electrostatic spraying.
Maximum electrostatic voltage of 110 kV with controllable low current ensures optimal transfer efficiency and surface quality.
All main units use 485/Modbus RTU bus connections for data communication.
Centralized control function for multiple guns: one or several units can be set as the master.
In multi-gun applications, adjusting the master unit’s parameters automatically synchronizes all slave units.
Each gun is equipped with three miniature electronic proportional valves for precise adjustment of powder feed, atomization, and cleaning air pressure.
Spray program setting and storage (up to 60 programs), retrievable at any time.
Pressing the AUTO key automatically adjusts powder output: reduced at close range, increased at long range.
Pressing the CLEAN key shuts off high voltage and automatically opens the air proportional valves to maximum for thorough cleaning of the powder pump, powder hose, and gun interior.
Pressing the BACKSPRAY key activates the backspray mode, while fine parameter adjustments can also be made via control keys.
Automatically control the voltage and current of the charging power area
- For different working environments, different products,and different powders, by setting the value of μA, we can find the most suitable electrostatic voltage and current values for the best spraying effect at the appropriate spraying distance. Effectively overcoming the phenomenon of "Faraday electrostatic shielding" and "reverse ionization" phenomenon, to obtain relatively good spray performance.
Advantage of XR5 controller
- Automatically control the voltage and currentof the charging power area
- The spray gun automatically adjusts low voltage andcurrent at short distances ;high voltage and current atlong distances. And good spraying results for complexparts and large boards.
- Through the setting of μA value, on differentworkpieces and different powders, multiple groups ofspraying methods can be recalled from memory, whichcan better optimize the effect of spraying.
- Automatically change the electrostatic voltage andcurrent of spraying, reduce the amount of excesscharge during electrostatic spraying operation, thuseffectively overcome the "Faraday electrostaticshieldingphenomenon" and "reverse ionization"phenomenon in electrostatic spraying operation, andimprove product surface quality and T/E , saving production cost.
