DC Master 24/12 24–30A alaldur

This step-down DC-DC converter steps down voltage from a 24 V battery bank to power 12 V devices. It is suitable for leisure and semi-professional applications.

It delivers a continuous current of 24 A (326 W) and can provide a peak power of 30 A (408 W) for a maximum of two minutes, which is ideal for handling inrush currents when starting certain devices.

The 81400330 model is a non-isolated converter. This means it has a common electrical connection between input and output (negative to ground). This design provides excellent thermal efficiency and a compact form factor.

Yes. As a non-isolated model, it is specifically designed for negative-ground installations.

Yes, it is mandatory to include a fuse in the positive wiring, placing it as close as possible to the battery for safety reasons.

No, the standby consumption of this model is extremely low. It draws less than 15 mA when not in use, preserving the energy of your battery bank.

The converter is very compact. It measures 167 x 87 x 50 mm (height x width x depth) and weighs only 0.62 kg.

It accepts a nominal input voltage of 24 V, with an operating range from 20 to 32 V DC. It can tolerate fluctuations up to 35 V DC without damage.

Yes, the converter provides a stabilized output voltage of 13.6 V, ensuring reliable and safe power supply for all your onboard electronics.

Input and output connections are made using Faston-type terminals. The required Faston connectors are included in the packaging.

A cool, dry, and well-ventilated location is recommended. Although the device has an IP53 protection rating, proper ventilation is essential for its natural cooling.

No, this model uses natural cooling. It has no internal fan, allowing it to operate completely silently.

Peak capacity allows for up to 30 A (408 W) for a maximum of two minutes. This is ideal for handling temporary power spikes, such as starting an electric motor or powering certain devices.

As this model is non-isolated, it is suitable for most equipment. However, for very sensitive communication devices requiring complete interference suppression, a galvanically isolated model from the DC Master range may be more appropriate.

For safety reasons, you must first connect the two input wires (from the 24 V battery). Only then can you connect the output wires (to your 12 V equipment).

The converter has an IP53 protection rating. This means it is protected against dust and water spray (up to 60° from the vertical), but it must not be submerged or exposed to direct jets of water.

The anodized aluminum housing promotes heat dissipation. The device operates optimally up to 30 °C. Beyond that, a linear power reduction (derating) applies up to a maximum temperature of 80 °C to protect the components.
