Published: 20 March 2012 - Michelle Winny
A DC input 1U rack mounted front-end power module has been developed by Powerstax which joins the companies existing range of AC input models.
The company’s D0601 is designed to operate as part of a DC-UPS or distributed DC power system, with or without battery backup and operates over the input range 80-350VDC. Typical applications include; telecom and data-com equipment, file servers, storage systems and networking solutions, distributed power systems and large battery charging applications
Three modules mcan be incorporated in a 1U rack shelf to provide 24, 28, 48, 54.5 or 56.2VDC output with up to 1800W total output power or 1200W in N+1 redundant mode. The module has comprehensive protection and alarm features including; over voltage and over current protection, over temperature warning and protection, power fail warning and alarm, remote on/off and load remote sense.
The modules feature active load sharing and up to 12 units may be connected for redundant parallel operation. Other standard features include high efficiency, up to 80 percent, hot-swap connectivity, low start-up temperature of -30ºC, operating temperature range up to 60ºC, front panel LED status indicators and I²C bus for monitoring voltage, current and temperature by network host systems. Powerstax are also able to supply a matching rack shelf complete with I²C monitoring.
