TDK-Lambda News

TDK Corporation (TSE:6762) announces the expansion of the TDK-Lambda brand GUS series of compact, single-output general-purpose power supplies with 600 W and 1000 W models. Designed for applications such as light industrial equipment, factory automation, semiconductor fabrication, ATE test systems, LED lighting, and broadcast, the new models deliver high efficiency, long life, and reliable performance.

The new GUS models provide output voltages of 12, 24, 36, and 48 V, achieving efficiencies of up to 95 % with a load of 30 to 100 %. This enables significant annual energy savings in excess of hundreds of kW hours. Both units feature an internal cooling fan with a low acoustic noise, typically less than 45 dBA, ensuring quiet operation in noise-sensitive environments.

The series addresses a market requirement for manufacturers who require a power supply with a high level of reliability, long electrolytic capacitor field life, and high efficiency performance at an economical price.

The GUS600 model measures 101.6 x 41 x 152.4 mm (W x H x D), while the GUS1000 has a compact package size of 101.6 x 41 x 177.8 mm. Both models offer a compact footprint, helping engineers maximise available system space. The models feature an operating temperature range of -20 to +70 °C and are backed by a three-year warranty. The output voltage can be adjusted for non-standard system voltages, and output remote on/off is available as an option.

Safety certifications include IEC/EN/UL/CSA62368-1 (compliant to IEC61010-1) and carry the 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 GUS series also meets IEC 62477-1 (OVC III) and has an input-to-output isolation of 2,000 Vac, input-to-ground of 3,000 Vac, and an output-to-ground of 500 Vac.
