TDK Corporation introduces the TDK-Lambda CUS200M series of medically and ITE certified power supplies. Featuring efficiency levels of up to 94%, internal heating is reduced allowing electrolytic capacitor life to be extended. The CUS200M can deliver 200 W convection cooled and up to 250 W with 1.5 m/s airflow and is packaged in the industry 3" x 5" standard footprint. Applications include hospital, dental, broadcast, test, and measurement equipment, particularly where audible fan noise is not desired.

Operating from a universal input of 85 V_AC to 265 V_AC, the CUS200M series is available with nominal outputs of 12 V_DC, 18 V_DC, 24 V_DC, and 48 V_DC, which can be adjusted via a potentiometer. All the models can deliver full power with ambient temperatures of -20°C to +50°C and 50% power at +70°C. An open collector DC good signal, remote on/off and a 5 V standby output (0.6 A convection, 1 A forced air) is included as standard on all models. Off-load power draw is less than 0.5 W when in standby mode.

The CUS200M series is safety certified to ANSI/AAMI ES 60601-1, IEC/EN 60601-1, IEC/UL/EN 60950-1, and carries the CE mark for the low voltage and RoHS2 directives. With an input to output isolation of 4,000 V_AC (2 x MOPPs), 2,000 V_AC input to ground (1 x MOPP), and 1,500 V_AC (1 x MOPP) output to ground, the series can be used in BF rated medical equipment. The series is also compliant to EN 55011-B, EN 55022-B, and FCC Class B for radiated and conducted emissions and the IEC 61000-4 immunity and IEC 61000-3-2 harmonic current standards.
