PULS have a range of conformal coated power supplies which are suitable for many environments where dust, contaminants, occasional high humidity, vibration or thermal shock can be expected, devices with conformal coated PC-boards are recommended. Thereby, a significantly higher operational safety can be achieved by avoiding short circuits and corrosion of conductors and solder joints.

The protective coating is made with an acrylic varnish, The coating process is a dip coating and has no impact on the electrical performance of the power supply.

The typical field applications are:

Paper mills and paper processing industry which must be immune against all kinds of dust and electrostatic discharge.

Railways and construction machines with continuous vibrations and rapid temperature changes.

Farms, where fumes (barns, silos, etc.) are present and resistance to insects is required.

In protected outdoor areas, where moisture and condensation is occasionally present.

Systems which are cooled with fans, resulting in extreme dust deposits.

Subtropical regions with long lasting high humidity along with high ambient temperatures.

Lighting, advertising displays and score boards which are located in protected outdoor areas.
The following power supplies are available with conformal coated PC-boards as a stock item:

Most other models can be equipped with conformal coating, please contact us regarding this.
