Providing High Current Outputs for Cash Deposit Machines

Vega AC-DC Power Supply

Although many retail payments are made electronically, cash is still used on a regular basis. High street banks now frequently offer cash deposit machines to small businesses as a way of quickly and accurately paying in their daily receipts. This helps both the banks and businesses reduce the amount of time to make these transactions.

Requiring high power 12V and 24V outputs to drive motors with a minimal 5V 15W output, a manufacturer of cash deposit kiosks chose TDK-Lambda’s Vega modular power supplies. A combination of high and low power modules can be selected, tailored exactly to the needs of the equipment, optimised with the use of an online configurator.

Climate Chambers Benefit From Compact Power Supplies

RFE Single-output 1U front end power supplies

Climate chambers are traditionally used for testing products under extremes of temperature or humidity. New applications are now being found, where materials or finished products are climate-conditioned prior to assembly or use. These chambers can now be seen in high volume production lines, even for automotive part manufacturing.

As space is typically at a premium on a production shop-floor, overall equipment size is important. Smaller power supplies allow for more space to process materials and parts. TDK-Lambda’s RFE1600 power supplies are now in use in climate chambers, chosen for their very compact size. Measuring just 40.6mm high and 85mm wide, they offer very high power density for a 1600W output power supply.


Power Supplies for Digital Printing

HFE Front End Power supply

Digital printing using inkjet technology is now being used for printing on other materials besides paper. Custom laminate flooring designs for example can be easily manufactured to suit the exact needs of an installation. The use of digital techniques and inkjets allow for short run manufacturing and colour repeatability for additional parts like mouldings.

Chosen for power density, TDK-Lambda’s rack mounted HFE1600 series were selected by designers of a large scale digital printer. As a standard industrial power supply, the product is readily available and offers the additional benefit of having the ability to provide redundant operation for maximum up-time. With current sharing, the number of HFE modules can also be configured to meet higher power requirements by plugging in additional units.

Wireless Network Reliability


Security is an essential feature for many corporate networks, especially where financial transactions are being performed. Gaming machines are now being linked via wireless networks to accept electronic payments, rather than relying on wired networks. The wireless routers used also have to be very reliable as downtime can result in significant loss in revenue, in addition to poor customer satisfaction.

One manufacturer of wireless routers chose TDK-Lambda’s ZPSA40 series to power routers used in gaming applications. To reduce assembly costs, the /P version is being used, allowing the ZPSA to be mounted directly on the printed circuit board. Pins on the ZPSA replace the Molex connectors, removing the need for cable harnesses and improving reliability.


Powering ATCA Applications

ATCA (Advanced Telecommunications Computing Architecture) was originally developed for carrier grade communications, but has since expanded to other applications like high performance computing. In a typical configuration, an ATCA shelf is 12U high with a 1U high power supply rack mounted at the bottom.

The HFE series of hot-swap, plug-in power supplies was developed by TDK-Lambda for a wide range of applications, including computing. The 48V output 2500W HFE modules were picked to power a new ATCA system, offering up to 10,000W in a 1U rack because of product reliability. Technical support was also provided to the customer as they required a PMBus™ communications interface for remote programming and monitoring.


Powering Magnetic Resonance Scanners


Magnetic Resonance scanners are regularly used by radiography units in hospitals to examine patients. As they do not use any ionizing radiation, they are often preferred over CT machines. The electronics in MR scanners requires multiple low noise outputs, and the power supply design is quite complex, often requiring a full custom design.

TDK-Lambda has produced a number of medical power supplies for these types of applications, and because of their experience and knowledge was asked to develop a new low earth leakage current design with over 20 outputs. The 700W product even features a programmable logic device interface via fibre optics.

Power Supplies for Scanning Electron Microscopes


A Scanning Electron Microscope (SEM) does not use a traditional light and lens to magnify the sample under inspection, but produces an image by scanning it with a focused beam of electrons. This produces an extremely high resolution image. For high throughput, multiple samples can be loaded, even when high pressure or low vacuum modes are required.

TDK-Lambda’s 48V 600W HWS power supplies are being used on the latest generation of SEMs. The “PV” option was chosen which allows the output voltage to be programmed over a wide 9.6 to 52V range by a 1-6V external signal. As acoustical noise can cause operator fatigue, the low noise fan (LNF) option was also incorporated in the power supply. This model is also covered by a TDK-Lambda’s limited lifetime warranty.

TDK-Lambda unveils new products at electronica 2016

TDK-Lambda will be exhibiting at electronica during November 8th – 11th, 2016 in hall A2, stand 205. The highlights will be our new 1500W QM7 modular series and the DRL series of 10 to 100W DIN rail mount power supplies, along with many other exciting products.

The QM7 is the first 1200-1500W series of modular supplies to have full MoPPs isolation, allowing them to be used in BF rated equipment. With the QM7’s high efficiency, less waste heat is generated and slower speed fans can be used. This makes it the lowest acoustic noise 1500W rated modular available on the market. The QM is suitable for a wide range of medical equipment, test and measurement, broadcast and renewable applications where high audible noise cannot be tolerated. The QM7 can supply up to 16 regulated outputs with voltages ranging from 2.8V to 52.8V and currents up to 110A and is supplied with an industry leading seven-year warranty.

For the first time, TDK-Lambda’s DRL series of rugged plastic encased DIN rail mountable power supplies will be on view. These highly efficient 12V or 24V Class 2 output 10W, 30W, 60W and 100W products have Class II double insulation allowing them to be safely used without a ground connection
Also the metal cased DRB480-24-1 will be making its debut. This economically priced 480W, 24V output DIN rail power supply has a high 6W per cubic inch power density, allowing it to be used where space is at a premium.

The three-phase industrial TPS3000 is being shown for the first time. With PMBus™ control this 3000 to 3200W power supply is capable of operating from either a 3-phase Delta or Wye configuration at 400/440/480Vac nominal inputs.


Ultra-narrow, low profile DIN rail power supplies have very high efficiencies

TDK Corporation announces the introduction of the DRL series of 10 to 100W DIN rail mount AC-DC power supplies with efficiencies of up to 90%. Featuring a low profile and very narrow width, the units are ideally suited for wall mounted enclosures commonly used in building automation and security applications. With an average efficiency of up to 87%, the DIN power supplies also meet ErP efficiency standards.

Housed in a robust plastic case, the DRL series has a common depth and height of 55.6mm and 91mm respectively, and widths of 18, 36, 54 and 72mm for the 10W, 30W, 60W and 100W rated models. The supplies operate from a wide range input of 85 – 264Vac and can withstand a 300Vac peak for five seconds. All package sizes have a 24V output and 12V is available for the 10, 30 and 60W models. The 30, 60 and 100W outputs are adjustable either from 12 – 15V or 24 – 28V.


The DRL has a Class II (double insulated) construction, requiring no earth ground connection, and 3,000Vac input to output isolation. Off-load power consumption is less than 0.3W for the 10 and 30W and less than 0.5W for the 60 and 100W versions. All models are convection cooled and are rated for operation in -20 to +71°C ambient temperatures (derating applies at high temperature).

The units are certified to IEC/EN/UL/CSA 60950-1, UL 508, are CE marked for the Low Voltage, EMC and RoHS2 Directives, with select models complying to NEC Class 2 in accordance with UL1310. All models meet EN55022-B conducted emissions, EN55022-A radiated emissions, EN 61000-3-2 harmonic currents and EN61000-4 immunity standards.
