Aluminum coloring AC or AC+DC power supply Colouring process AC or DC/AC method, you define the colour and the process time! Power supply for electrolytic coloring of Aluminum, the energy saving technology combined with easy to operate colouring controller ensures uniform colouring results for the processes of Electrolytic colouring of aluminium using the two-steps process: AC or DC/AC method. Suitable for coloring such as stainless steel color, champagne color etc. light color, deep color such as deep bronze color, pearl black color. and titanium gold color, golden brown color etc. gold color.   Technology Advantages Preset 20 different colorsprocess achievable, with colour and process time settingReproducibility of the colouring processIntegrated colouring and re-colouring functionPreimpregnationtime, DC time, coloring time, color compensation time could be adjusted independently, each process time could be adjusted.DC and AC operationMicroprocessor controlledMains voltage fluctuations do not affect the colouring resultThree phase mains supply used, so no unbalanced mains load as with normal two phase circuitsElectricity Energy cost saving with colouring times shortened by up to 50%Integrated with voltage regulator: only using thyristorwithout voltage regulator, the output AC sine wave may not be continuous, which may not be able to meet your color requirement, such asthere will be color difference at different place on aluminum, the color is not consistent;the color is not even.Ampere-hour and pre-selection counterHigh control accuracySoft-start functionsTiming function, when the coloring time is up, it will alarm with sound and lightTechnical specificationsoutput currents from 500A-20,000Aoutput voltage 22V, 25VRegulation error < ±1% in relation to nominal DC valueEfficiency > 87%Voltage regulation: Thyristor+voltage regulatorInput Voltage: AC 3 phase, 380V, 220V, 415V, 480V, 50/50HzOutput type: AC or AC+DCOutput Waveform: DC, AC Symmetrical sinewave or AC Asymmetrical sinewaveCooling method: Water coolingor air coolingFully digital controlcontrol systemTouch screen controlOptional color: 20 colorsEquipped with remote central control boxTouch panel colors setting
