    Effortless handling of difficult processes

    The TruPlasma DC Series 4000 (G2) was specially developed for reactive DC sputtering with heavy materials. The generators, which work with pulsed direct current, are particularly well proven in critical PVD and PECVD processes, which require both the highest coating quality and productivity. The compact DC process power supplies can be used in both pulsed and bias mode – two devices in one housing!

    High coating quality and productivity

    Digital signal processing guarantees stable processes and minimal arc-related time losses.

    The best results, even in critical processes

    Fast arc handling combined with DC pulse technology minimises substrate damage.

    Simple process adjustment

    Thanks to a broad frequency spectrum and adjustable reverse voltage.

    Compact and robust design

    The integrated water cooling saves space and reduces maintenance outlay.

    Hard material coating

    Hard material coating

    The addition of functional coats gives heavy-duty workpieces increased surface hardness and static friction as well as better thermal and chemical stability. The pulsed generators of the TruPlasma DC Series 4000 (G2) ensure a stable plasma process and thus optimal coating quality.

    Ideally suited to the application of the thinnest metal layers


    Paper-thin metal layers can be added to various materials using a PVD process to provide them with optimal optical and electrical properties. A power supply that has been optimally adapted to the process parameters enables the deposition of absolutely homogeneous, defect-free layers.

    Photovoltaic cell production

    Photovoltaic cell production

    In order to influence their electrical properties, photovoltaic cells, flat screens and touchscreens are coated with electrically conductive materials (TCO). As a result of their very low arc energy, the pulsed generators of the TruPlasma DC Series 4000 (G2) are ideally suited for this application.

    Architectural glass

    Architectural glass

    The large-scale coating of architectural glass during a PVD plasma process places particularly high requirements on the process power supply. The pulsed generators of the TruPlasma DC Series 4000 (G2) offer the ideal conditions for a high-quality coating result.

    Arc management

    High coating quality and productivity

    The combination of fast arc handling and DC pulse technology results in a lower droplet rate and fewer surface defects. Arc-related process interruptions are minimised and the deposition rate is increased significantly.

    Sophisticated monitoring tools to support your process

    Flexible adaptation to the process

    The pulse frequency can be adjusted within a wide range; it is also possible to operate the DC generator in bias mode. This means you can use the same device for a number of applications. Sophisticated monitoring tools support you in the optimisation of your process.

    Various options enable optimal adjustment of the pulsed DC generator to your application.

    Parallel operation and synchronisation

    Several DC generators in the TruPlasma DC Series 4000 (G2) can be operated simultaneously. This mode enables the synchronisation of the arc recognition of several generators geared toward different targets. The pulse mode can also be synchronised.

    User-friendly software PVD Power

    PVD Power

    The user-friendly, multilingual PVD Power software offers you numerous operation, configuration and diagnosis options for optimising process quality and effective error correction: display of 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 visualisation of important operating parameters with high temporal resolution (oscilloscope function).
