250-500W, Wide Range Input,

Non-isolated, DIN Rail DC-DC Converters

The DDA DIN rail mount, non-isolated step-down converters are ideal for creating additional high current output voltages from a single output 12V, 24V or 48V

AC-DC power supply. The highly efﬁcient DDA series accepts a very wide DC input and has a wide output adjustment range, with a choice of single or dual

output models.
