powerMELA.dcdc 12
Power converter

The powerMELA.dcdc converter is a DC voltage converter especially conceived for use in hybrid and electric vehicles with a galvanically isolated switching regulator.

With the wide input voltage range from 400 – 800 V and the output voltage, which can be adapted at any time, the converter completely replaces the function of an alternator.
In the different variants, different uses in cars, commercial vehicles and mobile machines are equally possible, and the converter can serve both as a charging device for vehicle
batteries as well as for the battery-free supply of low voltage devices.

If an external energy supply (e.g. a battery) is connected to an output, the supply connection (pole +) next to the supply must be protected. Recommended values for the protection: 1.1..1.2 X Inom.

Inrush current warning: no limiter has been provided.

Input fuse (external connection)/the value must be correctly chosen according to the application.

In case of polarity inversion the input fuse is triggered (in HV-input of the DC/DC converter there is no integrated protection for polarity inversion – optional protection against polarity inversion on request).
