Przetwornica DC Master 24/12 24-30A

This buck converter steps down voltage to power 12 V devices from a 24 V battery bank. Suitable for recreational and semi-professional marine 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 at startup for certain devices.

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

Yes, exactly. As a non-isolated model, it is specifically designed for installations with the negative grounded.

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

No, the standby power consumption of this model is extremely low. It draws less than 15 mA when not in use, which preserves the energy in 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 secure 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.

Choose a cool, dry, and well-ventilated location. Although the device has an IP53 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.

The 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.

This model is non-isolated, making it 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 water jets.

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