1600-Watt AC-DC power supply introduced by TDK-Lambda for robotics, test, and RF amplifiers

SAN DIEGO, 20 March 2013. TDK-Lambda Americas Inc. in San Diego is introducing the RFE1600 1600-Watt single-output AC-DC power supply for applications that require 12-, 24-, or 48-volt-DC bulk power in communications, factory automation, test and measurement, robotics, broadcasting, and RF amplifiers.

The output voltage is user adjustable enabling the RFE1600 to be used in a variety of customized applications.

Operating efficiencies of as high as 92 percent minimizes wasted heat dissipation and system cooling issues. The power electronics device features a universal input of 85 to 265 volts AC with PFC.

Models with a " and S" suffix include the optional I2C and PMBus serial communications port for remote control and monitoring.

These supplies can be used individually or as many as 10 units can be connected in parallel for high power or N+1 redundant power systems, facilitated via built-in ORing FETs and active current share ports.

Each power supply has two variable-speed cooling fans and the supplies can operate in temperatures ranging from -10 to 70 degrees Celsius. The RFE1600 has a power density of 23.5 Watts per cubic inch with dimensions of 12.6 by 3.35 by 1.61 inches.

Overvoltage, overcurrent and overtemperature protection are standard features, and for system monitoring there are opto-isolated signals for DC-OK and AC-fail, along with a LED indicators for DC-OK or fail conditions. Remote On and Off control is standard as is an auxiliary 12-volt and 0.5-amp output.

The power supply is EN55022 and FCC EMC compliant, and is certified to UL and EN 60950-1, 2nd Edition, safety requirements and carries the CE Mark.
