250W Medical and ITE 3x5” Footprint Power Supplies are 94% EfficientSan Diego, CA – June 2016 –

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 200W convection cooled and up to 250W with 1.5m/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 85-265Vac, the CUS200M series is available with nominal outputs of 12, 18, 24 and 48Vdc, which can be adjusted via a potentiometer.  All the models can deliver full power with ambient temperatures of -20 to +50oC and 50% power at +70oC.  An open collector DC good signal, remote on/off and a 5V standby output (0.6A convection, 1A forced air) is included as standard on all models.  Off-load power draw is less than 0.5W 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 4,000Vac (2 x MOPPs), 2,000Vac input to ground (1 x MOPP) and 1,500Vac (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.
