TDK-Lambda has continued to demonstrate its commitment to supporting STEM education by helping Ilfracombe Academy Year 12 A-Level students qualify for their Engineering Education Scheme (EES) certificates and British Science Association CREST Gold awards.
A team of four students from Ilfracombe Academy worked under the guidance and mentorship of Tim Puttick, Production Manager for TDK-Lambda UK. This year, students were tasked with establishing a method for handling and transporting heavy manufactured products safely for workers during product quality assurance. Previous projects have included controlling ambient temperature on the production line, calculating the facility’s carbon-footprint and developing a wind tunnel.

These projects allow students to develop valuable transferable skills not easily learned in the class room environment, including team work, project planning and presenting, writing program code, building prototypes and analysing return-on-investment for decision making.
Tim provided support and assistance to the pupils where needed, saying: “The project team undertook their challenge over a six-month period, successfully producing a solution that allowed a 28kg product to be handled and operated safely from manufacturing to testing, inspection and finally shipping”.
CREST Gold awards are widely recognised and respected by UCAS for university admissions in STEM subjects.
With three power level options, 15W, 30W and 60W, the KMS-A series medical AC-DC power supplies is available in 5V, 9V, 12V, 15V and 24V output voltages with product efficiencies as high as 89%. All models are certified to UL/CSA/IEC/EN 60950-1, ANSI/AAMI ES60601-1 and IEC/EN 60601-1.
Medical safety compliance extends to providing 4kVac, 2 x MOPPs (Means of Patient Protection) input to output isolation and a touch current of <100µA at 264Vac. With a Class II input, the KMS-A series require no earth ground connection, making them ideal for use in a range of medical, dental and home healthcare applications.

The RFE2500 series of 2500W AC-DC power supplies have a very low 1U (41mm) profile, feature efficiencies of up to 93% and have power densities of up to 27W/in3. Models are available with 12V, 24V or 48V outputs, with cooling from variable speed fans to reduce audible noise. Models can be paralleled to achieve higher power or for redundant operation using the internal ORing MOSFETs. An optional PMBus™ interface allows programming of the output voltage, activating the remote on/off and monitoring of the output voltage, output current, internal temperature and status signals.
TDK Corporation is pleased to announce that a team of technical experts from TDK-Lambda UK helped bring electronics engineering to life for children and young adults at this year’s Big Bang Fair South West. Held at Exeter University, the one-day event attracted 1,800 students looking to explore the possibility of following a career in a Science, Technology, Engineering and Maths (STEM) related subjects.

“Many local businesses participated in the event to showcase their industry to students,” said Anne Sutton, Training and Development Officer at TDK-Lambda UK. “The interactive activities, live demonstrations and quizzes held during the event helped inspire young students, enabling them to discover how STEM school subjects can lead to fantastic, rewarding careers.”
The Big Bang is a national programme that celebrates STEM and incorporates the National Science and Engineering Competition (NSEC). TDK sponsored the award for the ‘STEM Club Best Project’ category as part of this, and TDK-Lambda UK’s Product Performance Manager, Alex Knill presented the award to Treviglas College for their winning entry entitled: Nature Gardens Power Generation.
TDK-Lambda UK has manufactured electronic power supplies in Ilfracombe for 50 years and offers a large number of career development opportunities. For more information on the current opportunities available, please email your interests with Anne Sutton directly at: email@example.com
TDK Corporation announces the introduction of the 12V, 24V and 28V output HQA DC-DC converters, with additional output voltage models to be added in the coming months. Packaged in a ruggedised quarter brick form factor, the encapsulated HQA120 models can deliver 120W output power and will operate over a 9V to 40V input range (50V for 1 second). These 89% efficient converters are suitable for use in COTS, communications and industrial equipment.
The HQA120 has been qualified using methods consistent with MIL-STD-883 & 202, and offers a two screening and operating temperature options. The M-Grade has functional testing in cold, hot and room ambient temperatures, and an extended 96 hour burn-in with ten-cycle temperature testing. The S-Grade has functional testing at room ambient temperature and a standard burn-in period. The full load operating temperature for the M-Grade is -55 to +115°C and -40 to +115°C for the S-Grade.
Two baseplate mounting versions are available. The flanged format measures 60.6mm x 55.9 mm x 12.7 mm, with the non-flanged following the standard quarter brick format and measuring 60.6mm x 39 mm x 12.7 mm. Negative logic remote on/off and remote sense is provided.
All models are fully regulated, have a constant switching frequency for easier system EMC integration and utilise no opto-couplers in the control loop for increased reliability. Full auto-recovery protection is provided and the output can be adjusted ±10% or turned on or off remotely.
Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. Input to output and input to baseplate isolation is 2250Vdc.
