The ICT Isolated Series converters have been designed to operate from a negative or positive ground electrical system, providing complete isolation between primary and secondary circuits, as well as isolation from the chassis. Standard voltage ranges include: 12VDC-12VDC, 12VDC-24VDC, 12VDC-48VDC, and wide range inputs of 20-60VDC-12VDC or 50-100VDC-12VDC. Extra input filtering and spike detection are standard and essential for all applications including site, heavy-duty industrial and off-road equipment.
