Particle filters for our laboratory power supplies

In general, laboratory power supplies are designed for laboratories and production lines with a low or no pollution level. However, there are many applications where these requirements for the pollution level are not fulfilled. As a result, dirt enters the units through the air perforations. Dirt then settles in the units and can create conductive connections, which can result in a short-circuit. In the worst case, the laboratory power supply is destroyed.

To prevent this, we offer the option of an additional filter for our AC and DC sources, electronic loads and bidirectional sources to protect against dirt. This filter is fixed in front of the air ventilation perforation and can be exchanged or cleaned quickly. The reinforced internal fan guarantees that the required internal air flow is ensured.  The additional function offers reliable protection and allows users to operate their system safely under the given conditions.
