Original Press Release

1U High Industrial Power Supplies Have PMBus(TM) Communications

Press release date: Oct 25, 2016

TDK Corporation announces the introduction of the TDK-Lambda brand RFE2500 AC-DC power supplies. Delivering up to 2500W output power in a low profile 1U package, the RFE series has rugged screw terminal and bus-bar connections. These industrial supplies are ideal for use in many applications requiring reliable 12V, 24V or 48V bulk power.

Operating efficiencies of 90 to 93% minimizes waste heat dissipation and eases system cooling requirements. With a universal input of 85 to 265VAC applications for the RFE2500 supplies include communications, factory automation, test, measurement, and broadcast/RF amplifiers.

The RFE2500 is fully featured with AC Fail, DC Good, remote on/off, remote sense, a 12V 0.5A auxiliary supply, +/-20% output voltage adjustment (by either front panel potentiometer, external resistance or a 0-5V signal) and over current set point programming. Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation.

The units can operate at full load in ambient temperatures of up to 50oC, and deliver 50% load at 70oC. The case measures 107 x 41 x 345mm, making it suitable for 1U high racking systems and the weight is just 2.5kg. Cooling is provided by two internal temperature controlled fans to reduce acoustical noise.

Models with a “/S” suffix include an optional I2C/PMBus™ serial communications port for remote programming of the output voltage and remote on/off. In addition the output voltage, output current, internal temperature and status signals can be monitored.

Input to output isolation is 3kVAC, with all models certified to UL/CSA 60950-1, IEC/EN 60950-1 and carrying the CE mark for the Low Voltage and RoHS2 Directives. All units meet EN55011/EN55022-B conducted emissions (Class A radiated) and comply with IEC 61000-3-2 harmonics and IEC 61000-4 immunity standards.
