Description

The HW/HC series power modules are isolated dc-dc converters that operate over a wide input voltage range of 18

to 36 Vdc (HC) or 36 to 75 Vdc (HW) and provide one precisely regulated output. The output is fully isolated from

the input, allowing versatile polarity configurations and grounding connections. The modules exhibit high efficiency,

e.g. typical efficiency of 87% 3.3V/5A, 86% at 2.5V/6A. Built-in filtering for both input and output minimizes the need

for external filtering. These open frame modules are available either in surface-mount (-S) or in through-hole form.
