Read MoreThe Deutronic DVCH3003-700 Series is a high-power, galvanically isolated DC/DC converter designed for demanding industrial mobility and high-voltage battery applications. Engineered to operate from a wide 400–900 Vdc input range, it delivers stable, regulated low-voltage DC power for auxiliary systems, control electronics, and onboard equipment.
With up to 3000 W output power and variants available at 12 Vdc, 24 Vdc, and 48 Vdc, the DVCH3003-700 is suited to applications such as industrial vehicles, marine vessels, and heavy-duty mobile machinery. Its robust aluminium enclosure, high efficiency (up to 95%), and wide operating temperature range ensure reliable performance in harsh environments.
Designed for system integration, the DVCH3003-700 supports parallel operation for increased output power, CAN communication for monitoring and control, and external cooling via the mounting surface. Multiple configuration options, including heatsink and liquid-cooling variants, allow the converter to be tailored to specific thermal and mechanical requirements.

|
Class A |
Unrestricted operation range |
The DC/DC converter operates as designed in compliance with the tolerances specified in the data sheet. |
|
Class B |
Lower and upper |
One or more functions may go beyond the specified tolerance. After returning to the unrestricted operation range, the DC/DC converter operates again as designed |
|
Class C |
Undervoltage and overvoltage range |
One or more functions do not work as intended. After returning to the unrestricted operation range, the DC/DC converter operates again as designed. |
