Deutronic DVCH1503-400 DC/DC Converter

The Deutronic DVCH1503-400 Series is a high-performance, galvanically isolated DC/DC converter designed for demanding mobile power applications operating from high-voltage DC battery systems. Optimised for reliability in harsh environments, the series converts a 400 Vdc nominal input into stable low-voltage DC power for auxiliary loads, control electronics, and onboard systems.

*Evaluation criteria for the operation behaviour

The following evaluation criteria describe the functional state of the DC/DC converter as a function of the operation input voltage

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
restricted operation range

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.
