DESCRIPTION
The DH40 series is the latest generation of high performance DC/DC converters setting a new standard
concerning power density. These converters offer 40 Watts of continuous output power in a 2.0” x 1.0” x 0.4”
encapsulated, shielded metal package. The DH40 series has single and dual output models with 2:1 wide input
voltage ranges of 9-18VDC, 18-36VDC, and 36-75VDC. Advanced circuit topology provides a very high
efficiency up to 92% and an operating temperature range of -40°C to +80°C. Further features include remote
on/off, trimmable output voltage, under-voltage lockout as well as over load, over voltage, short circuit, and over-
temperature protection. These converters are RoHS compliant and are ideal for use in battery operated equipment,
instrumentation, distributed power architectures in communication and industrial electronics and many other space
critical applications.
