High-reliability DC-DC converters for power electronics in robotics and railway applications offered by TDK
SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the 200- and 300-Watt TDK-Lambda CN-B110 series of half brick DC-DC converters for robotics, automated vehicles, scientific research, and railway applications.
Capable of operating from an input voltage of 43 to 160 volts DC, the converters are compatible with 72- or 110-volt DC nominal railway systems.
These second-generation converters are available with 12-, 13.8, 15-, and 24-volt outputs. Using the trim function, users can adjust them for using a resistor or an external voltage to compensate for voltage drops, or to accommodate non-standard system voltages.
The standard models have non-latching self-recovering over current and overvoltage protection, with an option for latching with manual reset.
The CN-B110 has 11.8-millimeter spacing between the primary input and baseplate for a 2,500-volt AC isolation voltage. Input to output isolation is 3,000 volts AC and output to ground 500 volts AC.
With efficiencies to 91 percent, the power electronics device can operate at baseplate temperatures of -40 to 100 degrees Celsius, with minimal derating at high temperatures. Cooling comes from the optional heat sinks or to a cold plate via the module's aluminum baseplate.
Parallel operation using the current share function with as many as 11 modules is possible to support redundant applications. The CN-B110 has a DC good signal and remote on/off as standard, with an optional 12-volt 10-milliamp auxiliary output.
Overall dimensions are 12.7 millimeters high, 61 millimeters wide, and 57.9 millimeters long.
All models carry the CE and UKCA marks for the low-voltage and RoHS Directives, and are certified to the IEC/UL/CSA/EN 62368-1 safety standards. In addition, the series meets the rolling stock IEC 61373 Category 1, Class B shock / vibration standards and are designed to meet EN 45545-2 for fire protection on railway vehicles.
