Power source VARIO TS 3000 DC

The ELMA-Tech DC- power source VARIO TS 3000 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).

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. Based on the segment structure of the Virtual Machine the ELMA-Tech power source makes it possible that all parameters can be adjusted optimal in physical values on the respective process phase.

Characteristics

Advantages in comparison with primary-clocked power sections:

Galvanic isolation of the power source from mains
Wide supply voltage range
Flexible input voltages for the world wide operation
(3x 208V, 3x 380V, 3 x 400V, 3x 460V, 3x 575V; 50 / 60 Hz)
with always same configuration of the power sections without pre-transformer
More robust and safer because of lower DC-voltage on the power section (90 V DC) in comparison with primary-switched power sections (at 400V mains approx. 580 V DC)

Information on the acoustic emission level

The welding current source produces a sound level of < 65 dB(A) when idle and of< 65 dB(A) at the maximum admissible operating point during standard load in accordance with VDE 0544-1 and EN 60974-1, respectively. The sound label is measured in accordance with DIN 45635. The sound level is measured from a distance of 1 m from the welding current source. A workplace-related sound level during operation cannot be offered, since same is influenced by the type of process and the surroundings. It largely depends on a variety of parameters, such as machines in the vicinity, peripherals units, spraying head, plasma head, etc.
