San Diego, CA – TDK-Lambda has introduced the RFE1000 series; a new 1kW single-output AC-DC power supply in an ultra low profile (only 1.61” high) 1U pack-age for stand alone or distributed power architectures (DPA). These supplies are ideal for applications requiring reliable 24V, 32V or 48VDC bulk power. Up to +20% and -10% output voltage adjustment is possible, enabling the RFE1000 to be used in a variety of customer specific applications. Operating from a universal input of 85 to 265VAC with PFC, typical applications for the RFE1000 supplies include communications, factory automation, test & measurement, robotics and RF amplifiers. Efficiency of up to 88% minimizes heat dissipation.
The RFE1000-24, -32 and -48 power supplies can be used individually, or up to 8 units can be connected in parallel to form an N+1 redundant power system with built-in ORing diodes. Each power supply has variable-speed cooling fans and can operate in tempera-tures ranging from 0 to +70°C. The RFE1000 has a power density of 10.5W/in3 with dimensions of 12 x 5 x 1.61 inches.
Overvoltage, overcurrent and overtemperature protection are standard features, and for system monitoring there are opto-isolated signals for DC-OK, AC-fail and overtemperature warning, along with a 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 12V/0.25A output.
As well as being EN55022 and FCC EMC 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 factory warranty.
The new RFE1000 family of power supplies is available now and priced at $295.00 each in 1000 piece quantities. More information can be obtained at the following TDK-Lambda website http://us.tdk-lambda.com/lp/products/rfe-series.htm or by calling 800-LAMBDA-4.
