1.6-kW Supplies Feed Redundant Systems

Groomed for use in distributed, hot-pluggable and redundant power systems, the 1.16-kW HFE1600 series front-end power supplies with active PFC operate off a universal ac input from 85 to 265 Vac and provide dc outputs of 12V, 24V, or 48V.  Operating efficiencies up to 92% are typical. Housed in 19-inch rack-mount enclosures, as many as five supplies can be paralleled with automatic load-sharing to provide up to 7.6 kW of output power. An optional MCU allows for remote programming, monitoring, and status reporting via an isolated I²C and PMBus interface. Additionally, the HFE1600 supplies measure 1.61” x 3.35” x 11.8”, employ two variable-speed cooling fans, and can operate in temperatures ranging from -10°C to 7+0°C. Pricing starts at $515 each/500.
