This section of induction heating using low-voltage DC power supply 12-48VMaximum current 20A, maximum power 1000W.Tested 53V power supply when working properly.Because of its moderate power, can be used for small parts DIY players do hardening, annealing and other heat treatment,Also can be used with a graphite crucible melting gold, silver, copper, aluminum and other metals,uniform heating fast, very convenient.24V input with no load current of 3A48V input with no load current of 6AThe higher the voltage, the greater the heating current when the same thing, the effect is better,But at the same time heat is also large, so to eradicate the actual situation to select the input voltage,the general use of the words 24V or 36V power supply is enough.Colour:As shownMaterial:MetalSize:100mm x 100mmPackage Contents:1 x High Frequency Machine ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
