Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced the launch of its second generation of power supplies dedicated for Marine applications and demanding industrial systems. Responding to a demand from Marine equipment manufacturers to simplify logistics and to reduce energy consumption, the PT578 integrates programed digital protection, built-
“Introduced in 2005, the concept of immersed data-
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. The limits regarding mechanical and climatic requirements are also more demanding than for typical industrial applications. Vibration levels up to 4g are common, as well as large temperature fluctuations from -
To guarantee the highest level of safety, marine power architectures and immersed computing designs often require redundant power sources. To ensure this, several power supplies are usually connected in parallel, linked to each other through external ORing diodes modules. To simplify installation and utilization, the PT578 has built-
Depending on the application, the output protection may need a different type of configuration (Switch off, Hiccup mode or Constant current), which is one of the features included in the PT578. Based on firmware defined profiles and the output protection the mode of operation can be selected via a DIP switch with factory default settings though, in case of specific demand, it is possible to reconfigure any of the profiles at one of our PRBX Configuration centers. The unit also includes a DC OK signal and a potential free relay contact for fault protection. A front LED indicates power unit status (OK or Fault).
When Constant Current mode selected, the PT578 behaves as a current generator and is suitable for high capacitive loads, driving DC motors, and as well an ideal solution to charge a second level battery backup for critical equipment such as navigation systems.
PT578 will operate with wide AC input voltages of 90 to 265 VAC and with a DC Bus voltage of 125 to 375 VDC. The input AC frequency is of 47-
Two versions with adjustable output voltages are available in standard, 24VDC (23 to 29VDC) and 48VDC (47 – 56VDC) with an output power of 500W with peak power up to 750W during 10 seconds.
Designed to meet international Marine requirements, the PT578 complies with vibration specified in the DNV-
Using high density integration building practice, the PT578 is housed in a 132 x 67 x 128 mm (excluding the DIN-
The PT578 also meets and complies with related chapters of the EN61000-
Founded in 1974, with headquarters in Sweden and operations in 15 countries across four continents, Powerbox serves customers all around the globe. The company focuses on four major markets -
