DC current source VARIO TS 1500 DC

The ELMA-Tech DC- power source VARIO TS 1500 DC is a fully electronic secondary-clocked high-power source for the arc spraying process with constant voltage or with constant current voltage regulation (digital switchable). The power sources can be connected in parallel for both operation methods, using 2 pieces of 1500 A in parallel a power source with 3000 A can be provided at any time. Control The control concept of the Virtual Machine allows to configurate the power source complete new in static and dynamic by a cycle speed of 50 μs. The parameter for static and dynamic characteristics are selectable in real text in physical values, so that a 100 % reproducability of the generated process understanding is given. These parameters make it possible to optimise the power source characteristics and therewith the spraying properties for different conditions e.g. spraying speed. Statics und dynamics in conventional power sources are determined by the configuration and the coupling of the transformer and inductor and thereby defined by the hardware. Segment structure The process is classified in different segments from start to stop: LIBO START: increasing of electric arc STRIKING: absorption of electric arc WELDING: spraying segment SPRAYING-END: separation of penetration bead, wire burn-back In every of these segments the spraying process requires different power source properties both for the constant current and for constant voltage, particularly in the range of static and dynamic.
