Description
The CW025 Dual Output-Series Power Modules are
a family of dc-dc converters that operate over an
input voltage range of 36 Vdc to 75 Vdc and provide
two regulated outputs. These modules offer low
noise levels with industry-standard pinouts in a small
footprint. Each highly reliable and efficient unit fea-
tures remote on/off and current limit.
Each output is individually regulated by its own con-
trol circuit and has an independent overvoltage
clamp. With standard outputs of ±5 V, ±12 V, and
±15 V, the CW025 Dual Output-Series is flexible
enough to provide modified standard units with any
combination of output voltages from 2 V to 15 V.
Efficiency greater than 80%, a wide operating tem-
perature range, and a metal case are additional fea-
tures of these modules.
