Description
The EHW007A0B, Eighth-brick low-height power module is an isolated dc-dc converters that can deliver up to 7A of
output current and provide a precisely regulated output voltage of 12.0V over a wide range of input voltages (V
IN
= 36
- 75Vdc). The modules achieve typical full load efficiency of 92.5%. The open frame modules construction, available
in both surface-mount and through-hole packaging, enable designers to develop cost and space efficient solutions.
Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and
overtemperature protection.
RoHS Compliant
