200-250W Open Frame or Enclosed

TDK Corporation has introduced 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, 36 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.

  • Up to 94% efficient
  • Industry standard 3x5” footprint
  • 5V standby, remote on/off and DC Good signal
  • Medical and ITE certifications
  • Add /A suffix for cover option

350-420W U-Channel

TDK Corporation has introduced the 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.

Carrying a 3-year warranty, the CUS350M series is currently available with 12V, 18V, 24V, 36V 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.

  • 350W output power without external airflow
  • Medical and ITE certifications
  • Efficiencies of up to 94%
  • Fully featured (/F suffix)

  • CUS350M-36: 36V 9.7A, 349W convection cooled, 36V 11.5A, 414W forced air
  • CUS350M-48: 48 7.3A, 350W convection cooled, 48V 8.7A, 418W forced air



300W External

TDK Corporation has announced the introduction of the TDK-Lambda medical and ITE certified DTM300-D external power supplies.  This series offers a choice of class I or class II (no ground connection) inputs and meets the stringent Level VI DoE standards for efficiency and off-load power.  The DTM300-D is certified to both the medical IEC 60601-1 and ITE IEC 60950-1 standards, making it suitable for a variety of power hungry medical, industrial, and test and measurement applications.

The convection-cooled DTM300-D is housed in a rugged, vent-free enclosure, measuring 222mm x 112mm x 45mm (LxWxH).  AC is applied using the standard IEC 60320-C14 (3-prong) or 60320-C18 (2-prong) connector and DC provided through a ten-pin Molex Mini-Fit® connector.  Other connectors are available upon request.  The adapters also feature over-voltage and over-current protection.

Accepting a 90 to 264VAC input, the 300W adapters are available with 12V, 19V, 24V, 28V, 48V and 54V outputs and can operate in ambient temperatures ranging from -30 to +60°C (derating linearly to 50% load from 40 to 60°C).  In addition to satisfying DoE Level VI requirements with an average efficiency of greater than 88%, the power supplies have an off-load power draw of less than 0.5W.

The DTM300 has been certified to IEC/ES/CSA/EN60601-1, IEC/UL/CSA/EN60950-1 and carries the CE mark for the Low Voltage, EMC and RoHS2 Directives.  All models meet EN60601-2, IEC60601-1-2 Ed4:2014, EN55011/EN55022 Class B, EN55024 Class B, FCC Part 15 Class B, FCC Part 18 Class B emissions and immunity standards.  Input to output isolation is 4,000Vac (2 x MoPP), with a touch current of <100µA.  Class I models are suitable for BF rated equipment with an output to ground isolation of 1,500Vac..

  • Compliant with DoE level VI requirements
  • < 0.5W off-load power
  • Medical and ITE certifications
  • Class I or Class II (no ground connection) inputs
