The LTH400 Series DC/DC converter was designed for 12VDC input applications and is part of a wider range of units that are available with input voltage options up to 130VDC It is a mature design with a proven track record in many applications.

The unit is equipped with reverse polarity protection on the input, surge protection and input & output filtering.Cooling is by natural convection and optional ruggedizing & conformal coating is available, for immunity to shock, vibration, humidity, moisture, dust and insects.

An optional redundancy diode allows parallel connection to achieve higher output power or N+1 redundancy. This chassis-mount design is optimized for low component count and high efficiency.
