Lambda / TDK / EMI NV-175

The TDK-Lambda NV-175 is a configurable AC/DC power supply for industrial, commercial, and medical applications. Delivering 175W, 180W, or 200W depending on configuration, this compact 3" × 5" module integrates into host equipment with high efficiency up to 90% and power density suitable for sensitive electronics. Universal input acceptance (90–264VAC, 47–63Hz, also 440Hz with reduced PFC) combined with active power factor correction and 1–5 configurable output channels makes the NV-175 adaptable to diverse system requirements.
