Brick: 60Watts
The ALD12/18/20/25 series is Astec’s latest 16
th
Brick industry standard offering. Operating from an input voltage range of 36V to
75V, the series provides 6 configured outputs from 1.2V all the way up to 5V. It delivers up to 25A max current for 1.8V and
lower at impressive levels of efficiency. The series comes with industry standard features such as Input UVLO; non-latching OCP,
OVP and OTP; Output Trim; Differential Remote Sense pins. With its wide operating temperature range of -40°C to 85°C
ambient, the converters are deployable into almost any environment.
