Up to 20% output voltage adjustment is possible enabling the RFE1600 to be used in a variety of customer specific applications including battery charging. Operating from a universal input of 85 to 265VAC, 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 to +70°C. With overall dimensions of 85 x 41 x 320 mm (3.35 x 1.61 x 12.6in) the TDK-Lambda RFE1600 power supply achieves a power density of 24W/in 3.
Overvoltage, overcurrent and overtemperature 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 is remote sense and an auxiliary 12V 0.5A output. An I 2C PMBus compatible interface is available as an option for all models.
As well as being EN55022 and FCC compliant (achieving class B conducted and class A radiated emissions), the RFE1600 series meets UL/EN 60950-1 safety approvals and carries the CE mark. Harmonic correction meets the EN61000-3-2 standard and immunity meets the IEC61000-4-2, -3, -4, -5, -6, -8 and -11 standard, and the TDK-Lambda RFE1600 power supplies are backed by a 3-year warranty.
