DC/DC converters

Efficient and reliable PULS DC/DC converters provide regulated DC voltages of 12 V, 24 V or 48 V.

An efficient DC/DC converter can do more than just adjust voltages. It can contribute to system reliability and increase endurance in the event of voltage fluctuations.

The compact design allows installation in standard decentralized on-machine cabinets and saves plenty of space on the DIN-rail.

What is the need for a DC/DC converter?

A DC/DC converter can be installed to rectify the conditions of a voltage drop and “dirty” DC voltage in large or remote applications. This means, a DC/DC converter will take a DC input voltage, filter it and then produce a regulated DC output voltage. Depending on the model, a DC/DC converter can also step up or step down the DC voltage: e.g. from a DC 48 V input to a DC 24 V output.

Which applications profit most from a DC/DC converter?

The DC output voltage of a power supply can be affected by various factors such as wire size and length as well as electrical noise. Especially in large applications, long wire lengths are a reality and are required to connect all the control equipment in the system. If this is combined with a small wire size the DC voltage loss can be substantial. This will possibly affect the connected loads. Even if the wire size is appropriate for the load, peak currents such as starting motors can further increase the voltage loss. A DC/DC converter is a tried and tested solution to solve these problems.

How can a DC/DC converter help in remote applications?

In remote sites we often face DC only control applications. This means the DC voltage is the only available voltage and comes from a source like a battery, solar panel or DC fed from a local panel.

In addition to the voltage drop caused by the wire length, wire size and current draw, the DC voltage can also be made “dirty” by the electrical noise interjected into the wires by the surrounding equipment. Under those harsh conditions some loads will stop operation because of the large drop in DC voltage. Many DC/DC converters, on the other hand, can operate on a wide input range. The devices are able to take a compromised DC voltage, clean it up and produce a regulated DC voltage on the output.
