Powerbox announced the release of a ruggedized dual channel power supply for marine engine control. Based on a ruggedized platform for use in harsh environments, the ENMA500D24/2×27-CC provides two 27V/20A isolated outputs and a total power of 540 W. The power supply is housed in a robust IP56 case, it is mechanically designed for efficient conduction cooling, and it complies with DNV/GL standards.
Powerbox is one of Europe’s largest power supply companies.
Powerbox and on-board electronics
From local low power DC/DC converters powering sensors to high power DC generators powering the whole boat, ships and vessels are full of electrical and electronic equipment requiring robust and safe power supplies.
Although many applications can be powered by marine certified commercial off-the-shelf power supplies, others are very specific, requiring unique power solutions designed to pair with the final application.
FSV operation is based on servomotors ensuring that fluids are transferred or interrupted with the highest level of safety. As failure is simply not an option in such types of equipment, FSV manufacturers often use two independent power supplies to guarantee redundancy. However, considering the equipment is installed in very compact and harsh environments, this can be a challenge for the installer.
Power supply for harsh environments
Because they are often used in harsh environments, the ENMA500D24/2×27-CC is built in a robust IP56 case, resistant to high-pressure and heavy sprays of water. Being sealed to comply with IP56, the ENMA500D24/2×27-CC DC/DC converters have been designed and optimized for conduction cooling. Two lateral heatsinks facilitate the thermal exchange between the inner dissipating components and the ambient outside.
