3T SERIES
Single output
• • • • • • • 75% efficiency UL and CSA approvals Adjustable output voltage Logic inhibit Short circuit protection Parallelability Remote sense
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.
