TDK Corp. recently announced the introduction of TDK-Lambda's CUS350M medical and ITE certified 350W 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.
The CUS350M series is currently available with 12V, 18V, 24V, or 48V outputs with a user adjustment of +/-5% to accommodate non-standard voltages. The series can reliably provide up to 350W output power (convection cooled) at 40oC ambient, and 175W at 70oC. With efficiencies of up to 94%, an average rating of 87% and a standby power consumption of less than 0.5W, the units comply with the European ErP Directive.
The units are enclosed in a compact 190mm x 87mm x 40mm (7.5" x 3.4" x 1.6") package and will operate from a wide 85 to 264Vac input. The fully featured "/F" suffix models include a 5V 0.5A standby output, a 12V 0.3A auxiliary output, remote sense, an isolated DC Good signal and remote on/off function. Input to output isolation is 4,000Vac (2 x MOPPs) and 1,500Vac (1xMOPPs) 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 and 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.
