Both models meet the requirements of IEEE 802.3af which defines the specifications to deliver power over standard Ethernet cables.
At 1U high, these compact units offer 48VDC at 1200W – a power density of 15Win³ – with full power factor correction, and up to three hot-swap units can be housed together in a 19in rack to give a total power output of 3600W. Input voltage range is the universal 85 to 264VAC and all models feature a 5V standby output. Output isolation (an important requirement for PoE applications) is 1500VAC.
With an ambient operating temperature range of 0 to 70ºC and cooling by integral fans, the new PowerCassettes incorporate a number of features designed to simplify their application. These include active current sharing, LED status indicators and optional I²C serial data bus control and monitoring.
