CUS350M Series Power Supplies

TDK Corporation announces the introduction of TDK-Lambda's CUS350M medical and ITE certified 350 W power supplies. Requiring no external airflow, the series is suitable for hospital, clinical, dental, and home-based medical applications, as well as professional broadcast, test, measurement, and audio equipment where low-audible noise is demanded.

Carrying a three-year warranty, the CUS350M series is currently available with 12 V, 18 V, 24 V, or 48 V outputs with a user adjustment of ±5% to accommodate non-standard voltages. The series can reliably provide up to 350 W output power (convection cooled) at 40°C ambient, and 175 W at 70°C. With efficiencies of up to 94%, an average rating of 87%, and a standby power consumption of less than 0.5 W, the units comply with the European ErP directive.

The units are enclosed in a compact 190 mm x 87 mm x 40 mm (7.5" x 3.4" x 1.6") package and will operate from a wide 85 V to 264 V_AC input. The fully featured "/F" suffix models include a 5 V, 0.5 A standby output, a 12 V, 0.3 A auxiliary output, remote sense, an isolated DC good signal, and remote on/off function. Input-to-output isolation is 4,000 V_AC (2 x MOPPs) and 1,500 V_AC (1 x MOPPs) input-to-ground and output-to-ground.

The CUS350M power supplies are certified to IEC/EN 60601-1, ANSI/AAMI ES 60601-1, and IEC/EN/US 60950-1. These power supplies are CE marked for the Low Voltage and RoHS2 Directives. The units also comply with EN 55011-B, EN 55022-B, and FCC Class B for conducted emissions (Class A radiated), and meet the IEC 61000-4 immunity and IEC 61000-3-2 harmonic current standards.
