Powerbox offers a range of high-voltage input dc/dc converters for microgrid, datacenters, and industrial applications. The PQB-PHB-PFB300S series converters operate with an input voltage range of 180 Vdc to 425 Vdc and deliver output power levels from 150W to 750W. The range of applications powered by high-voltage DC supplies is rapidly expending, and from the latest microgrids and datacenters using high voltage DC (HVDC) bus voltages to reduce power losses through to industrial systems, all of these applications require ready to use, board-mounted power converters. Powerbox’s PQB-PHB-PFB300S series is specially designed for such applications. They are built around a high efficiency topology, have a layout optimized for thermal conduction, an input/output isolation of 3,000VAC minimum and deliver output voltages from 3.3 Vdc to 48 Vdc.
In order to provide a solution for any application powered from a high-voltage bus, the PRBX PQB-PHB-PFB300S series includes four power levels (150, 300, 600 and 750W) in three industry-standard packaging formats and footprints; quarter, half and full-brick. The 150W rated PQB150-300S is packaged in a quarter-brick format, has an input voltage of 180VDC to 425VDC and offers seven different output voltages; 3.3VDC/30A, 5.0VDC/30A, 12VDC/12.5A, 15VDC/10A, 24VDC/6.3A, 28VDC/5.4A and 48VDC/3.2A. The typical efficiency is 89%.
The PHB300-300S is a half-brick, 300W rated version with an input voltage of 180VDC to 425VDC and offers five different output voltages of 5VDC/60A, 12VDC/25A, 24VDC/12.5A, 28VDC/10.7A and 48VDC/6.25A. The typical efficiency is 89%.
The PFB600-300S comprises full-brick, 600W modules with an input voltage of 200VDC to 400VDC providing four different output voltages; 5VDC/80A, 12VDC/50A, 24VDC/25A, and 48VDC/12.5A. The power efficiency is typically 89% and up to 91% on the 24 and 48VDC outputs. For redundancy or additional power, the units include active current sharing.
The 750W PFB750-300S full-brick modules can be operated with an input range of 200VDC to 425VDC and are available in six different output voltages; 12VDC/62.5A, 15VDC/50A, 24VDC/31.2A, 28VDC/26.7A, 36VDC/20.8A and 48VDC/15.6A. The typical efficiency is 90% and the product includes active current sharing.
The PFB600-300S and PFB750-300S have an output trim range of 60-110% that facilitates using the modules as a constant current source or as a secondary battery charger. Designed for use in industrial environments, the PQB-PHB-PFB300S series can be operated within a wide temperature range of -40°C to +100°Cand in 95% of non-condensing relative humidity. The modules’ thermal shutdown is set to protect the units when the housing reaches +105°C.
