Introducing the RFE2500 1U 2500W AC-DC Power Supplies

RFE2500 Series

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.

High performance 120W DC-DC converters are suitable for harsh environments

LA006633 - HQA

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.

Class II encapsulated power supplies operate in high ambient temperatures

TDK Corporation announces the introduction of the KWS-A series of single output 5W to 25W encapsulated power supplies capable of operating in ambient temperatures of up to 85ºC. With a Class II input, the products require no earth ground connection, making them suitable for use in a range of process control, broadcast, test & measurement and industrial equipment.

LA3320 KWS-A Series image - low res

The board-mount product line-up comprises four power levels, 5W, 10W, 15W and 25W, and is housed in three compact package sizes. The 5W and 10W units measure 38.1 x 25.4 x 21.5mm, the 15W 50.8 x 25.4 x 24mm and the 25W models 63.5 x 25.4 x 29mm. Four popular output voltages are available, 5V, 12V, 15V and 24V, and all operate from a wide range input voltage of 85 – 265Vac, 47 – 440Hz.

The KWS-A can start up at -40ºC and operate without forced air cooling in ambient temperatures of up to 85ºC, and at full load over a -10ºC to +55ºC range (+45ºC for the 5V output 10W to 25W models). Off-load power draw is less than 0.5W and full load efficiencies are as high as 88%. Board design is made simpler and space minimised as no external fusing or electrolytic capacitors are required.

The series carries certification to UL/CSA/IEC/EN 60950-1 and the CE mark for the Low Voltage and RoHS2 Directives. All models comply with EN 55011-A conducted and radiated emissions (class B with the addition of a small X-capacitor) and EN 61000-4-2, -6-2 immunity standards.

Wide range non-isolated DC-DC converter series extended with new models

TDK Corporation announces the introduction of two further models to the TDK-Lambda i6A series of step-down, non-isolated DC-DC converters. The i6A4W is capable of supplying currents of up to 20A, and the i6AN allows the creation of negative voltages delivering currents up to 8A. Both can be used in conjunction with the previously announced 14A rated i6A series to generate additional system voltages from a high power, single output AC-DC power supply. Applications include medical, communications, industrial, test & measurement, broadcast and portable equipment.

LA006632 - i6A - lowres

The compact, PCB mount DC-DC converters have the industry standard 1/16th brick footprint and measure just 33 x 22.9 x 12.7mm. Ultra-high efficiencies as high as 97% are achieved, allowing operation in ambient temperatures of -40°C to +125°C with the appropriate de-rating. The thermal design of the series allows for minimised output de-rating, even in low airflow and high ambient temperature conditions. The product’s optimised dynamic voltage response reduces the need for external capacitors, saving cost and board space.

The i6A4W output is adjustable from 3.3 to 15V and can operate from a wide range 9 to 53V input. This module can also be used as a drop-in replacement for expensive, isolated, 1/16th brick converters driving 12V POL devices from a regulated 48V input. The i6AN can generate negative polarity 3.3 to 30V outputs from a positive 9 to 40V input.

Standard features include a trim pin for output voltage adjustment, positive remote sense, remote on-off (positive or negative logic), input under-voltage, over-current and over-temperature protection. Power good, operating frequency synchronisation and output sequencing are available as an option for the i6A4W.

Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. All i6A converters have a three-year warranty.

For more information about the full range of TDK-Lambda i6A series DC-DC converters, please call TDK-Lambda directly on +44 (0)1271 856600 or visit the TDK-Lambda website at: www.uk.tdk-lambda.com/i6a

Power Supplies for LED Video Displays

sws100l

Advertising has been radically changed with the extensive use of eye catching LED video displays.

These signs are often positioned outside and the reliability of power supplies is one essential factor for manufacturers. TDK-Lambda’s SWS series of 100W and 150W power supplies are being used in high profile displays because of their specification, and the availability of printed circuit board coating to avoid failures due to condensation or humidity.

3D Printing and Additive Manufacturing

Additive manufacturing (AM) utilising 3D printers offers many benefits including weight reduction, rapid prototyping, lower tooling costs and the ability to construct complex designs.

Vega

To satisfy the requirement for multiple output voltages and a large amount of 48V power, the nine output, 900W, modular Vega series and the rack mounted 2500W HFE power supplies are being used in a series of 3D metal additive printers.

HFE

The standard features of the two products were cited as a reason to use these power supplies.

Power supply manufacturer employees receive Level 3 ILM Certificates

TDK Corporation is pleased to announce that eight TDK-Lambda UK participants have received their Level 3 ILM Certificates. Following completion of the Management and Leadership development programme and gaining Institute of Leadership & Management Awards in ‘Leadership and Management’, all eight went on to gain certification.

LA007049 - Adam Rawicz, Managing Director at TDK-Lambda EMEA (2nd R), & Sharon Wingate, QLM trainer (far R), congratulate ILM graduates

The successful participants were Barry Skene, Sengyim Ng, Stuart Martin, Andrew Mansfield, Giorgio Ponzo, Kevin Tizzard, Daniel Massey and Chris Malvern.

QLM Ltd developed the ILM Award and Certificate programme, and was delivered in conjunction with the Institute of Leadership and Management (ILM) – the UK’s leading provider of leadership and management qualifications. The course gives candidates the skills and knowledge to lead, organise and motivate teams.

“The course gave a real insight into the fundamentals of management, from the importance of motivation, engagement and assertiveness through to the application of well-established theories to optimise efficiency and effectiveness,” said programme participant Barry Skene.

The General Manager at TDK-Lambda UK, Phil Scotcher, is an active supporter of the ILM programme: “I know that all the candidates learnt a lot and put a great deal of hard work and effort into completing the course. I have also seen how previous participants in the programme have benefited by using these extra skills to develop their own abilities and enhance inter-department relationships.”
