The HFE1600 series offers an "energy-saving" feature via the I²C/PMBus interface, so the units can be individually turned on or off as the total system load demand varies.
The HFE1600 series operate off a universal AC input from 85 to 265VAC, with active PFC, and provides a well regulated DC output of either 12V, 24V, 36V or 48V. Operating efficiencies of up to 92% are typical. With the 19-inch rack-mount enclosure, as many as five (5) supplies can be paralleled with automatic load-sharing to provide up to 7600W of output power. A popular option is an integral MCU in each supply that allows for remote programming, monitoring and status reporting via an isolated I²C and PMBus interface. And, an "energy-saving" feature of the I²C/PMBus interface is that rack-mounted HFE1600 supplies can be individually turned on or off as the total system load demand varies over time (aka "load-shedding").
Key applications for the HFE1600 series include data centers, wireless base stations, industrial automation, telecommunications, RF power amplifiers, network equipment, storage systems, burn-in systems and distributed power architectures.
The HFE1600 supplies, each measuring only 1.61"H x 3.35"W x 11.8"L, as many as five (5) can be mounted in an 1U-high 19-inch rack enclosure to form a paralleled connected, load-sharing, hot-swap, N + M redundant 7.6kW power system. Should a fault occur, each supply has an internal ORing MOSFET switch that will automatically disconnect it from the load and the other paralleled supplies. Plus, alarm signals and LED indicators are provided to identify a faulty unit. For added power, up to two (2) rack-mounted enclosures can be parallel or series connected.
And, for higher power applications, up to two (2) power racks containing up to ten (10) model HFE1600 supplies can be zero-stacked (no space required between racks) and connected in "parallel" to provide up to 15.2kW of total output power in a compact 2U vertical space. Likewise, up to two (2) rack-mounted sets with five (5) units each can be connected in "series" for higher voltage requirements at up to 15.2kW.
The 19-inch rack mount enclosure is available with AC inlets via IEC320-C16 connectors or terminal blocks for each of the five (5) power module slots. All units in the HFE1600 Series are fully RoHS-compliant, carry the CE mark and meet UL/EN60950-1 safety specifications, as well as EN55022 and FCC level B EMC conducted specifications. The radiated EMC performance complies with Level A requirements.
