Compact single output, general-purpose power supplies series

June 2025

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda GUS350 series of compact, single output general-purpose power supplies. The models are rated at 350W with 12, 24, 36 and 48V outputs. The GUS350 is convection-cooled and is available with output voltage adjustment function, remote on-off, and DIN-rail mounting bracket options.

The GUS350 series addresses the need for an economically priced product, while maintaining reliability and quality. This provides an alternative source of power for manufacturers who require a higher grade of construction without significantly impacting cost. The GUS350 models measure 101.6 x 41 x 127 mm (W x H x D) and have an operating temperature from -20 to +70°C, with a three-year warranty. With efficiencies of up to 95.5%, energy consumption and internal losses are reduced, lowering internal component temperatures and enhancing long-term product reliability.

Safety certifications include IEC/EN/UL/CSA62368-1 (compliant to IEC61010-1) as well as CE and UKCA marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions standards and meet EN 61000-3-2 harmonics and IEC 61000-4 immunity standards.

The GUS350 series meets IEC 62477-1 (OVC III) and has input-to-output isolation of 2,000Vac, input-to-ground 3,000Vac, and output-to-ground 500Vac.
