Traco Power TEN 3 - proven classic for industry

DC/DC converterIndustrial

TEN 3 series is our real „classic“. Since we introduced it to our offer, we have already sold more than 15 000 pcs without single complaint. Converters are manufactured solely from SMD components, which also help to maintain exceptional quality.

This is an archive article published 23.05.2017. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.
TEN 3 series offers 28 models of 3W DC/DC converters with input voltage range 2:1 and built-in input filter to meet EN 55022, Class A and FCC, level A without additional external components.

Series is designed for nominal input voltage 5, 12, 24 and 48V. Input voltage range is 2:1, which means 18 to 36V for nominal input voltage of 24V. Converter has short-time (1sec) overvoltage reserve, 50V for 24V version, which makes overvoltage protection design easier.

Output voltages are 3.3, 5, 12, ±5, ±12, ±15V, standard voltages used in digital and analog circuits. If short circuit on the output occurs, the converter limits current to 110% of output current. Short circuit duration is not limited. Once it is removed, the converter enters into normal mode automatically. Converter with a single voltage output can work with up to 4000uF capacitor connected to output.

Isolation parameters (1500V DC/60 sec and 65pF capacity between input and output) predestinate TEN 3 series for general purpose, for example for digital panel meters powered from 24V DC.
The use for power supply of powerful IGBT or GaN transistors should be carefully considered. Isolation has to withstand voltage switched by transistors, which may be kilovolts at PWM frequency tens of kHz. Isola-tion is subject to rapid voltage changes, which leads to faster degradation than with just DC voltage. Cur-rent flowing through the capacity of isolation barrier is I=C.dV/dt. Switch times are very short for modern IGBT transistors and dV/dt can be 10kV/us or more, for GaN transistors even 100kV/us. Current through barrier capacity can be 65e-12*10e3/1e-6=0.65A. This current penetrates to primary side of converter causing voltage spikes across connection resistances and inductances and can disrupt operation of the DC/DC converter’s controller.
