New from TDK-Lambda is the RFE1600 series of front end power supplies – 1,6 kW, 1U high units for standalone and distributed power architecture (DPA) applications requiring reliable 12 V, 24 V, 32 V and 48 V bulk power in the communications, test and industrial markets.
Up to 20% output voltage adjustment is possible, enabling use in a variety of customer specific applications including battery charging.
Operating from a universal input of 85 to 265 V a.c., the RFE1600 maintains over 90% efficiency, thus minimising heat dissipation. The RFE1600-12, -24, -32 and -48 models can be used individually or up to 10 units can be connected in parallel to form an N+1 redundant power system with internal ORing MOSFETs and single-wire current share.
Each power supply has two temperature-controlled internal cooling fans for longer life and can operate in temperatures ranging from -10°C to +70°C. With overall dimensions of 85 x 41 x 320 mm, the power supply achieves a power density of 1,46 W/cm³.
Over-voltage, over-current and over-temperature protection are standard features, and for system monitoring there are opto-isolated signals for DC Good, AC Fail and over-temperature warning, with a rear panel LED indicator for AC OK (green) and DC OK/Fail (green/red). Remote on/off control is also standard, as are remote sense and an auxiliary 12 V 0,5 A output. An I²C PMBus-compatible interface is available as an option for all models.
