TDK expands medical and industrial AC-DC power supply series, offering high power in compact, low-noise package

September 16, 2025

TDK Corporation (TSE:6762) announces the addition of 1200 W rated models to the TDK-Lambda CUS-M series of 30 W to 1500 W AC-DC power supplies. These latest products have a 187 x 93 mm footprint and a low 42.5 mm profile. The CUS1200M features a variable speed fan with audible noise as low as 30 dBA at 20 % load and 42 dBA at full load. The power supplies can be used in a wide range of applications, including medical, dental, test and measurement, broadcast, and industrial equipment.

The series accepts an 85 to 265 Vac input, delivering full power at 90 Vac, and is available with 24 V, 36 V, and 48 V outputs. A 5 V 2 A standby voltage, remote on/off, remote sense and a power good signal are fitted as standard. With efficiencies of up to 95.5 %, internal heating is reduced, allowing reliable operation in the compact size. The off-load power consumption is typically <0.6 W when the supply is put into standby mode. The CUS1200M models can operate in ambient temperatures between -20 °C and +70 °C, derating linearly at high temperatures. The CUS1200M series has a five-year warranty.

The CUS1200M series has an input to output isolation of 4000 Vac (2 x MoPP), an input to ground isolation of 2000 Vac (1 x MoPP), and an output to ground isolation of 1500 Vac (1 x MoPP) for B and BF rated medical equipment. The leakage current is <250 µA, with a maximum operating, transportation, and storage altitude of 5000 m.

Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with CE/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, and meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4, and IEC 61000-4 immunity standards.
