TDK Lambda NNS50-5 AC-DC Power Supply
The TDK Lambda NNS50-5 is an enclosed single phase AC-DC power supply designed for industrial automation systems. It provides a regulated nominal output of 5 Vdc at a maximum continuous output current of 10 A. The model spans an AC input voltage range from 85 Vac to 230 Vac across 47 to 440 Hz. This unit has a maximum rated output power of 50 W and an average conversion efficiency of 42%. The output voltage of the power supply can be adjusted within a specified range of 4.5 to 5.5 Vdc for application flexibility. For reliable power production, the maximum ripple and noise are limited to 1 mV RMS and 3 mV peak to peak. The model's line regulation is set at a maximum of 0.5 mV to ensure a steady output in spite of changes in input voltage. The load regulation ensures reliable and consistent functioning over the whole load range with a maximum rating of 1.5 mV.
The NNS50-5 incorporates overcurrent protection with an activation range set between 10.5 A and 13.0 A to safeguard the different components. The crowbar type overvoltage protection engages between 6.0 V and 7.2 V as an active output safety function. The inrush current at cold start is rated at 60 A at 100 VAC input and 40 A at 200 VAC input. These layered protection functions collectively make this model dependable unit for safety critical industrial applications. The power supply operates from – 20 °C to 71 °C using convection cooling without an internal fan. The full rated output is available from 0 °C to 50 °C with gradual derating applied at elevated operating temperatures. The vibration tolerance for the Power Supply is rated from 10 to 55 Hz at below 2G sweep amplitude on all three spatial axes. The shock resistance is rated at less than 20 G that ensures mechanical durability in demanding industrial field settings.
The NNS50-5 is housed in an enclosed unit type package measuring 97 x 113 x 200 mm overall. The total unit weight is approximately 4200 g making it a compact industrial grade power component.
