TDK Lambda announced the launch of TDK lambda brand RFE2500 series AC and DC power supply. The RFE series provides up to 2500 W output power in a low-key 1u package, with rugged screw terminals and bus bar connections. These industrial supplies are ideal for use in many applications requiring reliable 12 V, 24 V, or 48 V bulk power supplies. 90 - 93% operating efficiency minimizes waste heat loss and simplifies system cooling requirements. The general input of RFE2500 is 85 to 265 V (AC), and its application range includes communication, factory automation, testing, measurement and broadcast/RF amplifier.
RFE2500 has the functions of AC failure, DC good, remote on/off, remote sensing, 12 V 0.5 a auxiliary power supply,+/- 20% output voltage regulation (through the front panel potentiometer, external resistance or 0-5 V signal), overcurrent setpoint programming, etc. Up to 8 units can be connected in parallel to obtain higher power, and the internal toroidal FET allows redundant operation. The unit can operate at full load at ambient temperatures up to 50 ° C and provide 50% load at 70 ° C. The case measures 107 x 41 x 345 mm, making it suitable for a 1-u high shelf system and weighing only 2.5 kg. Cooling is provided by two internal thermostatic fans to reduce noise.
Models with "/S" suffix include optional I2C/PMBus serial communication ports for remote programming of output voltage and remote on/off. In addition, the output voltage, output current, internal temperature and status signal can be monitored. Input to output isolation is 3 kV (AC), all models have passed UL/CSA 60950-1 certification, IEC/EN 60950-1 certification, and carry CE marks for low-voltage and RoHS2 directives. All units comply with EN55011/EN55022-B conducted emissions (Class A radiation), IEC 61000-3-2 harmonic and IEC 61000-4 immunity standards
