RFE2500 industrial power supply provides 2,500-W output

TDK-Lambda announces the RFE2500 ac/dc power supplies that deliver up to 2,500-W output power in a low profile 1U package. They provide screw terminal and bus-bar connections that suit applications requiring reliable 12, 24 or 48 V bulk power.

 

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

The RFE2500 features AC Fail, DC Good, remote on/off, remote sense, a 12 V 0.5 A auxiliary supply, ±20% output voltage adjustment (by either front panel potentiometer, external resistance or a 0 to 5-V 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 supply weighs 2.5 kg and measures 107 x 41 x 345 mm, making it suitable for 1U high racking systems. Cooling is provided by two internal temperature controlled fans, which help reduce noise.

 

Models with an ‘/S’ suffix include an optional I2C/PMBus serial communications port for remote programming of the output voltage and remote on/off. Additionally, the output voltage, output current, internal temperature and status signals can be monitored.

 

Input to output isolation is 3 kVac, 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.
