These are hot swappable, offer an efficiency of 92% and feature a power density of 18.75W/in³, with output voltages of 48VDC and 54.4VDC. A 5V/1A standby output is also included across the series. The auro-he Series includes three standard models all with automatic load sharing and ORing circuitry as well as an I²C serial bus for external monitoring and control. Four auro-he units can be specified as a 19in power shelf delivering up to 6000W.
The units work from a wide AC input range with over 0.98 power factor and operate from -20 to +70ºC although they will start-up at temperatures as low as -40ºC but with reduced performance. Cooling is by dual-speed fans. Front panel LEDs indicate AC input and DC output status and input and overvoltage protection is standard as is a Class B EMI filter. The auro-he Series comes with a two year warranty.
