ALQ25 Series
(Open Frame Single Output Quarter Brick)
ALQ25 Single Output Open-Frame DC-DC Converter Module
Industry Standard
¼
Brick: 36V-75V Input / 5V Output
The ALQ25 series is Astec's next generation single output, high-density standard quarter brick offering. It operates from a 36V
to 75V DC Bus and comes in different Isolated Logic Output voltages (ILO) well suited for DPA applications. It’s designed to
conservatively handle 25A of output current for 5V and at high levels of efficiency (5V @ 91%). It provides tight regulation
and exhibits clean and monotonic output start up characteristics. The ALQ25’s come with industry standard features such as
Input UVLO, OCP, OVP, OTP, Output Trim, differential output Sense pins.
