Description

The QTS48T25120 bus converter provides an isolated step-down voltage from 48V to 12.0V nominal. The QTS is

an unregulated converter; therefore output voltage is directly proportional to input voltage with a conversion ratio of

4:1. The converter provides ultra-high efficiency; as a result very little heat is dissipated and a heat sink is not

required.

The QTS48T25120 is an excellent choice for intermediate bus application where multiple output voltages are

required and a 12.0V rail will be used to power point-of-load devices.
