DC/DC umbreytingarstöð Master DC/DC 24/12-12A

This converter steps down the voltage from your 24 V battery bank to provide a stabilized 12 V (13.6 V actual) power supply. It is ideal for powering your 12 V on-board equipment from a primary 24 V source.

This non-isolated model has a common electrical connection between the input and output (common negative). It offers excellent efficiency, heats up very little, and is more compact. Isolated models, on the other hand, galvanically separate the circuits, which is sometimes required for equipment highly sensitive to interference.

The converter delivers a continuous current of 12 A, i.e. a nominal power of 164 W. It also features a peak capacity allowing it to supply up to 18 A (245 W) for a maximum duration of two minutes.

Yes, provided the total consumption of your 12 V equipment connected simultaneously does not exceed 12 A continuous (or 18 A peak for start-up). Ensure you check the power requirements of your devices before connecting them.

Installation is very straightforward thanks to the supplied snap-in mounting bracket. Simply secure this bracket to a bulkhead using the included screws, then firmly snap the converter’s aluminum housing into place.

Yes, it is mandatory to include a fuse in the positive wiring. This fuse must be placed as close as possible to the 24 V battery to effectively protect your electrical installation against short circuits.

This model has an IP53 protection rating. This means it is protected against dust and water splashes (up to 60° from the vertical). It should still be installed away from direct splashes and immersion.

No, this converter uses a natural cooling system. It has no mechanical fan and operates completely silently without any wear on moving parts.

The idle consumption of this inverter is extremely low, less than 15 mA. Although minimal, it is recommended to install a main circuit breaker if you leave your boat unused for an extended period.

Input and output connections are made via Faston-type spade terminals. The required connectors are included in the packaging with the converter to simplify installation.

For communication or navigation equipment extremely sensitive to interference, a galvanically isolated model is often preferable. This non-isolated model is perfectly suited for lighting, pumps, or standard onboard electronics.

The housing is ultra-compact. Its dimensions are 127 x 87 x 50 mm (Height x Width x Depth) for a very light weight of only 405 grams.

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

Certain electrical devices (such as motors, compressors, or pumps) require a much higher current at startup. The peak capacity allows the inverter to supply 18 A for 2 minutes to absorb this inrush current without tripping or going into fault mode.

Yes, this non-isolated converter is specifically designed and suitable for standard marine installations with a grounded negative.

The converter is supplied as a complete ready-to-install package. The box contains the DC Master converter, its snap-in mounting bracket, mounting screws, and Faston connectors.

It can operate in ambient temperatures ranging from -25 °C to 80 °C. Note that beyond 30 °C, a linear power reduction (derating) is automatically applied to protect the device from overheating.

Although designed for 24 V systems, it accepts an input voltage range from 20 to 32 V DC to deliver its full power. It can tolerate peaks up to 35 V without damage.

Yes, the converter includes a stabilization function. It delivers a constant and smoothed output voltage of 13.6 V, protecting your sensitive equipment from voltage fluctuations in your main battery bank.

It is advisable to choose a cool, dry, and well-ventilated location. Although it is IP53 protected, avoid areas prone to strong water splashes, stagnant humidity, or intense heat sources to ensure optimal cooling.
