All PULS DIN rail power supplies feature robust electrical and mechanical designs. This robustness enables PULS products to achieve the highest energy efficiency and reliability ratings as well as very long service lifetimes, even under tough conditions. Nevertheless, extremely harsh environmental conditions like high humidity, condensation, high concentration of conductive particles, corrosive gases, heavy vibration, etc. may require additional considerations.

The use of power supplies with conformal coated PCBs is recommended to provide greater system reliability in challenging environments. PCBs with protective coating can prevent false traces that are caused by contamination. The risk of corrosion of PCB paths, electronic components, and/or soldered joints will also be greatly reduced.

The PULS product portfolio includes conformal coated versions for 50 W to 480 W power requirements with single phase and 3-phase input voltages.
