Product Details

The PQ60120QEx25 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. Targeted for use in intermediate bus architectures, this module supplies an isolated step down voltage from 35-75V to 12V and provides more available power and higher efficiency than most competitive bus converters. This converter is available in openframe and baseplated versions. RoHS Compliant (see last page).

Operational Features

• High efficiency, >96% at full rated load current
• Delivers 25A of Iout (300W) with minimal derating - no heatsink required
• Wide input voltage range: 35-75V
• Input voltage transient capability: 100V, 100ms
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
• Wide output voltage trim range (-50% to +5%)

Mechanical Features

• Industry standard pin-out configuration
• Standard Size Open Frame:1.45" x 2.30" (36.8 x 58.4mm)
• Total Open Frame height only 0.417” (10.59mm) permits better airflow and smaller card pitch
