General-purpose 350 W AC-DC power supply
October 2025
Electrical Power & Protection
The TDK-Lambda GUS350 series of compact single-output general-purpose power supplies are rated at 350 W with 12 V, 24 V, 36 V and 48 V outputs. They are convection-cooled and available with optional output voltage adjustment functions, remote on-off and a DIN rail mounting bracket option for the 24 V model.
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 mm x 41 mm x 127 mm (W x H x D) have an operating temperature range of -20 to 70°C, and come 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/CSA 62368-1 (compliant with -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 features input-to-output isolation of 2000 V AC, input-to-ground of 3000 V AC and output-to-ground of 500 V AC.
