TDK-Lambda adds 32-V model to HFE1600 front-end power supplies

TDK has announced the extension of its TDK-Lambda HFE1600 range of 1.6-kW high-density, front-end power supplies with the addition of a 32-V model. Particularly well-suited for use in broadcast applications, the HFE1600-32 operates from a universal 85 to 265 V AC input, and the high efficiency of up to 92% minimises heat dissipation and power consumption to meet Climate Savers Computing efficiency standards. The HFE1600-32 is equally well-suited for use in applications including communications, laser, and process control. As with other models in the HFE1600 range, HFE1600-32 AC-DC power supplies can operate individually or up to five units can mount into a dedicated 1U rack delivering 8 kW. To form a hot swap N+1 redundant power system, up to 10 units can be configured in parallel with single wire current sharing. TDK-Lambda has also integrated a keying system to prevent misinsertion of modules into adjacent racks of differing voltage. Output voltage is programmable by resistance, external voltage, or optional PM Bus compatible I²C communication interface. The HFE1600 hot-swap front-end power supplies comply with EN55022 and FCC Class A radiated and Class B conducted emissions and meet IEC61000-4 immunity. All models are safety approved to EN/IEC/UL 60950-1 edition 2 with CE mark and are backed by a three-year warranty. TDK-Lambda Product deeplink
