DESCRIPTION
The CMLV series consists of high density, low input voltage, isolated converters on a chassis mount with a wide input voltage
range. Low input voltage converters are uncommon in the industry and the CMLV series offers the flexibility of operation with
both 12V and 24V busses. These state-of-the-art converters’ features include fast transient response, short circuit protection,
over current protection, soft start, and many other features that are required for today’s demanding applications.
