The ELV series consists of high density, low input voltage, isolated converters with a wide input voltage range. Low input voltage converters are uncommon in the industry and the ELV series offers the flexibility of operation with both 12V and 24V busses. This state-of-the-art converter’s 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. This series is available in both encapsulated and open frame designs.
