DC Master DC/DC converter 24/12-12A

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

This non-insulated 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. Insulated models, on the other hand, galvanically isolate the circuits, which is sometimes required for equipment highly sensitive to interference.

The converter delivers a direct current of 12 A, i.e. a nominal power of 164 W. It also has 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 startup). Verify the power requirements of your devices before connecting them.

Installation is very simple thanks to the supplied snap-mount bracket. Simply secure this bracket to a bulkhead using the included screws, then firmly snap the aluminum converter housing into place.

Yes, it is essential to install 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 system against short circuits.

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

No, this converter uses a natural cooling system. With no mechanical fan, it operates silently and has no wear on moving parts.

This converter's standby power consumption 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 using Faston-type spade terminals. The necessary connectors are included in the packaging with the converter to simplify installation.

For communication or navigation equipment highly sensitive to interference, a galvanically isolated model is often preferable. This non-isolated model is suitable 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) with a very light weight of only 405 grams.

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

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

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

The converter is supplied as a complete ready-to-install package. The box contains the DC Master converter, its snap-on 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 derating (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 spikes up to 35 V without damage.

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

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