TDK-Lambda has introduced the RFE1000 series; a new 1 kW embedded 1U high single-output AC-DC power supply for standalone and distributed power architecture (DPA) applications requiring reliable 24 V, 32 V and 48 V bulk power. Up to 20% output voltage adjustment is possible, enabling the unit to be used in a variety of customer specific applications including battery charging.
Operating from a universal input of 85 to 265 V a.c., typical applications for the RFE1000 include communications, factory automation and RF amplifiers. Efficiency up to 89% minimises heat dissipation.
The RFE1000-24 ,-32 and -48 power supplies can be used individually or up to eight units can be connected in parallel to form an N+1 redundant power system with optional ORing MOSFETs. Each power supply has variable-speed cooling fans and can operate in temperatures ranging from 0°C to +70°C. The RFE has a power density of 0,64 W/cm³ with dimensions of 305 x 127 x 41 mm. AC input is via a terminal block and DC output is via M5 studs. Auxiliary outputs are via a JST type 12-way connector.
Over-voltage, over-current and over-temperature protection are standard features, and for system monitoring there are opto-isolated signals for DC OK, AC fail and over-temperature warning with a rear panel LED indicator for DC OK. Remote on/off control is also standard, as is remote sense. Other standard features include single-wire current sharing and an auxiliary 12 V 0,25 A output with built-in ORing diode.
As well as being EN55022 and FCC compliant (achieving class B conducted and radiated emission), the RFE1000 series meets UL/EN 60950-1 safety approvals and carries the CE mark. Harmonic correction meets the EN61000-3-2 standard, and the power supplies are backed by a two-year warranty.
