Product Details

The PQ24120QEx25 PowerQor Exa Quarter-brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC-DC converter. The Exa series offers industry leading power density for standard isolated DC-DC converters with both a wide input range and a tightly regulated output. This module supplies an isolated step down voltage from 18-36 V to 12V and provides more available power and higher efficiency than competitive converters. RoHS Compliant (see last page).

Operational Features
