DHW40

The DHW40 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 DHW40 series has single and dual output models with 4:1 ultra wide input voltage ranges of 9-36VDC and 18-75VDC. Advanced circuit topology provides a very high efficiency up to 90% 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.

Notes & safety
Notes: 1. Heatsink is available for models. Add “HS1” to model name for 24V model heatsink, or “HS” for other models.
2. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested capacitor: 330µF/100V.
3. It is recommended to protect the converter by a slow blow fuse in the input supply line.
4. Other input and output voltages may be available, please contact factory.
5. Do not exceed maximum power specification when adjusting output voltage.
