Energy-efficient step-down DC/DC converter generates less heat

PULS UK is launching the YD 25.241 non-isolated step-down DC/DC converter that has the ability to convert input voltages to pre-settable output voltages and also limit the current from 25A to 7A. With an input voltage range between 14 and 32V, the new device should prove particularly useful in applications where non-standard output voltages are required in a range from 3.3V. As a step-down converter the output voltage must be 1.5V less than the input voltage. The new device provides an output of up to 500W and can be used with battery or bus systems. A further use may be as a current-limit device to protect the 24V bus.

At present linear regulators are commonly used to reduce DC supply voltages, but these operate by bleeding off excess power as heat and therefore waste a considerable amount of energy. The advanced technology used in the PULS YD25.241 delivers much greater levels of efficiency and also dramatically reduces the heat generated within the host device.

Although only positive output voltages are possible, the unit is suitable for non-standard voltages below 26.5V, or where an intermediate (eg 12V) bus is required. The unit has self-adjusting overvoltage protection, active inrush current limitation and reverse input polarity protection.

As with all PULS products the YD25.241 can mount on DIN-rail, which makes installation simple and quick; at only 32 x 124 x 107mm, the compact converter is suitable for both new-build and retrofit applications.
