DC/DC Converters: PULS CD5 series DC/DC converters provide isolation and voltage regulation for applications with voltage drops due to long cable runs, unreliable sources such as batteries, and/or voltage conversion. The compact design of the CD5 series requires minimal mounting space and includes galvanic isolation and a soft-start feature. Additionally, many PULS Dimension series power supplies are designed and approved to operate with a DC input voltage for greater system flexibility and functionality.

DC Back-Up Systems: Power fluctuations and outages can severely disrupt and potentially damage control and communication systems, while also causing unexpected downtime. PULS offers a variety of DC back-up systems from electrolytic capacitor based buffer units to a unique one-battery concept DC-UPS system for increased system reliability.
