TDK-Lambda recommends a PCB layout with a solid copper ground plane and thermal vias to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended for the PCB.
To ensure reliable start-up, TDK-Lambda recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current. Additionally, the power supply should be derated according to the temperature derating curve provided in the datasheet.
The maximum cable length for the DC output cables depends on the cable size and type. As a general rule, TDK-Lambda recommends keeping the cable length as short as possible (less than 10 inches) to minimize voltage drop and ensure reliable operation.
Yes, the RSKN-2020 can be used in a redundant configuration. TDK-Lambda recommends using a diode ORing circuit or a redundancy module to ensure seamless switchover between power supplies in case of a failure.
The MTBF of the RSKN-2020 is calculated based on the Telcordia SR-332 Issue 4 standard. According to TDK-Lambda, the MTBF is approximately 1.5 million hours at 40°C ambient temperature.
