TruPlasma DC Series 3000 (G2)

Perfection for all surfaces

The latest generation of compact DC generators

The TruPlasma DC Series 3000 (G2) is suitable for a number of DC sputtering processes – including use as a replacement for pulsed process power supplies. This is because progressive arc management offers a guarantee for the best layer qualities and a significantly higher production yield. Because of its extremely compact design you can integrate the water-cooled DC generators very easily into your current application.

Lowest arc energy in its class

Residual energies of < 0.3 mJ/kW guarantee the best layer qualities and high deposition rates.

High power density

Very compact design (19-inch plug-in unit) results in simple integration, even for larger power levels.

Wide power range

Output power of 20 kW to 300 kW, so use as a replacement for larger generators is also possible.

Complete water cooling

Enables long system runtimes and reduces maintenance.

Simple system integration

Variable line voltage (400 V to 480 V) and different data interfaces.

Hard material coating

Hard material coating

The application of functional coatings using DC magnetron sputtering provides workpieces that undergo a lot of use with increased surface hardness and static friction, as well as better thermal and chemical stability. TruPlasma DC Series 3000 (G2) direct current generators ensure that the plasma process is stable and thus that the coating quality is optimal.

TruPlasma DC 3040 direct current generator


A PVD process is used to apply a paper-thin metal layer to various materials in order to provide them with the best possible optical and electrical properties. A power supply that has been optimally adapted to the process parameters enables the deposit of absolutely homogeneous, defect-free layers.

Photovoltaic cell production

Photovoltaic cell production

In order to influence the electrical properties, photovoltaic cells, as well as flat screens and touchscreens, are coated with electrically conductive materials (TCO). As a result of their very low residual arc energy, TruPlasma DC Series 3000 (G2) direct current generators are ideally suited for this.

Architectural glass

The large area coating of architectural glass in a direct current sputtering process places particularly high demands on the process power supply. TruPlasma DC Series 3000 (G2) direct current generators offer the ideal conditions for high-quality coating results.

Arc management

Low-cost alternative to pulsed generators

With their state-of-the-art arc management, TruPlasma DC Series 3000 (G2) direct current generators prove themselves in many sputtering processes. As a low-cost alternative to pulsed DC generators they also offer a significantly higher production yield.

The TruPlasma VHF Series 3000 generators offer unparalleled cost-effectiveness

Compact alternative for higher output

Despite their very compact design, the TruPlasma Series 3000 (G2) direct current generators beat even larger generators in terms of coating quality and productivity. They thus represent a compact and easily integrated alternative, even for a high output power of more than 60 kW.

DC generator with complete water cooling

Water cooling for longer system runtimes

TruPlasma DC Series 3000 (G2) direct current generators have their own complete water cooling system. Compared to air cooled devices, these systems enable a higher system runtime, reduce maintenance costs, and prevent contamination as a result of dust particles.

Various options enable optimal adjustment of the direct current generator to your application.

Parallel operation and synchronization

Several DC generators in the TruPlasma DC Series 3000 (G2) can be operated simultaneously. This mode enables the synchronization of the arc recognition of several generators geared toward different targets. The pulse mode can be synchronized as well. If high output power is required, a parallel circuit of up to 5 TruPlasma DC 3030 generators is possible. This functions as a TruPlasma DC 3150 unit.

Water valve control

Water valve control regulates the cooling water flow to avoid condensation and simultaneously protect the generator against overheating.

Equipped for every possibility

EtherCAT and EtherNET/IP interfaces enable simple integration of the TruPlasma DC Series 3000 (G2) in current systems.

User-friendly software PVD Power

PVD Power

The user-friendly, multilingual PVD Power software offers you numerous operation, configuration, and diagnosis options for optimizing process quality and effective error correction: display actual values for all relevant process parameters as well as warnings and alarms, specification of target values by the operator, as well as recording and visualization of important operating parameters with high temporal resolution (oscilloscope function).
