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

zpsa

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

med

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

hws

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.
