Powerstax, a specialist provider of custom power sources, introduced the FAC Series of slim Â½U-high baseplate-cooled power modules. Featuring power factor correction, these compact (2.2cm x 17.5cm x 18.0cm) units can deliver a 500W output from an 85VAC to 264VAC input. They are offered in 12VDC, 15VDC, 24VDC, 28VDC and 48VDC output options, with custom voltages available. Hold-up capability is built in to the unit, along with a convenient H15 connector to allow hot-swap redundancy. Designed for cold wall mounting, these modules are highly effective in applications where environmental considerations or space constraints mean that little (or no) forced air cooling can be provided. These include outdoor signage and telecommunications infrastructure (such as street cabinets, pico cell base stations, wireless access points, etc.), and industrial power systems. IEC60950-1 and EN 61000 compliant, the series operates within a temperature range spanning from -20Â°C to +100Â°C. A fan cooled version with a 1U height is also available for rack or system mounting, which is environmentally sealed and has a built-in heat sink. To increase power output levels, units can be paralleled by a simple single wire connection. This allows multi-kW systems to be realised. According to Rob Hill, Director of Sales & Marketing at Powerstax, "The FAC series combines high performance DC-DC converter technology with a sophisticated front end to create an ultra-low profile AC-DC power solution that is highly suited to power system applications where airflow is restricted. It underlines our ability to supply customers with power solutions that can deal with deployment in the most demanding conditions."
