These wide range input, three terminal, 25kHz switching regulators are versatile,
inexpensive, and efficient. They provide a single adjustable output from a DC
source. 75% typical efficiency is an added advantage of the switcher which
helps reduce transformer and heatsink requirements over an equivalent linear
regulator. Since their efficiency is essentially independent of input voltage,
output current need not be derated with increasing input voltage. Other
features include: short circuit protection; remote on/off; parallelability and
remote sensing. The 3T Series modules are unique open board DC/DC
converters that help solve tough power system requirements.

Line regulation is over the full +10V to 60V input range.
Load regulation is over the range of no load to maximum average output
current.
The current limit of 3T20AP is factory set at 24A to 27A. However, when
units are used in parallel configuration, the current limit should be set at
20A. Consult factory for a full explanation of parallel operation of 3T
regulators.
