Powerbox introduces four products within its Marine Line, PT570, PT571, PT576 and PT577, complying with the major classifications and approved by Det Norske Veritas (DNV), Germanischer Lloyd (GL) and major marine approval organizations. Designed for demanding applications requiring peak power, the new series can deliver 50% extra peak current for 10 seconds and exhibits high efficiency, up to 92%. The PT570, PT571, PT576 and PT577 can be operated from -25°C to +70°C without derating in convection cooled conditions. Built for robustness the new products are suitable for use in harsh environments with high vibrations, e.g. on diesel generators and all units are protected by conformal coating to withstand condensing conditions. The PT570 (250W) and PT571 (125W) are built-on baseplate technology whilst the PT577 (250W) and PT576 (125W) are made for DIN-Rail mounting
The requirements imposed on products responsible for shipping and offshore installations are greater than the average for industrial and office environments, requiring power designers to follow strict design rules and to select components and technology complying with international standards.
Generally two zones are distinguished on a ship; the “bridge and the open deck zone”, and the "general power zone", which basically cover all other areas in the ship. The open deck areas and bridge have extra demands on the electromagnetic emission and immunity (EMC), since sensitive equipment is positioned here, such as communication, radar and navigation devices. These EMC requirements regarding emissions are well below the known EN55022 Level B and measurement starts at 10 kHz, instead of the usual 150 kHz. All products are EN60945 compliant.
