PULS UK introduces 500W dc/dc down converter

24 February 2011

PULS UK has introduced the YD 25.241 non-isolated step down dc/dc converter that converts input voltages to pre-settable output voltages and limits current from 25A to 7A. With an input voltage range between 14 and 32V, the new device should prove useful in applications where non-standard output voltages are required in a range from 3.3V. The new device provides an output of up to 500W and can be used with battery or bus systems.

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 significantly reduces the heat generated within the host device.

Although only positive output voltages are possible, the unit is ideal for non-standard voltages below 26.5V, or where an intermediate (eg 12 volts) bus is required. The unit features self-adjusting over voltage protection, active inrush current limitation and reverse input polarity protection. The 32mm x 124mm x 107mm unit is DIN-rail mountable.
