Descrizione

DC-DC converter for stabilizing the power supply of 12V devices from 24V on-board systems. It is designed for applications with variable input voltage in the range of 1836V DC, where a high output current of up to 50A is required. The design in an aluminum finned housing allows natural cooling and the design with increased resistance is suitable even for more demanding operating conditions.

Installation and operating instructions

Observe the correct polarity of the input and output and ensure a firm mechanical mounting of the converter.

For currents up to 50A, use wires of the appropriate cross-section and minimize the length of the line; for longer wires, it is advisable to choose a larger cross-section.

Ensure heat dissipation from the housing and installation in a location with sufficient airflow; cooling is designed to be natural.

The output is non-isolated, so it is necessary to consider a common ground between the input and output.

Safety notice

The device operates with DC voltage up to 36V and high currents; in case of a short circuit or incorrect installation, the wires may heat up significantly and there is a risk of damage to the installation.

Perform the installation with the power disconnected and use wires and fuses rated for the given current.

In environments with increased humidity, follow the principles of proper sealing of cabling and bushings to maintain the resistance of the entire installation.
