TDK-Lambda To Show Power Supplies And Converters

TDK-Lambda UK will showcase a range of new AC/DC power supplies and DC/DC converter products at this year's Southern Manufacturing and Electronics exhibition. At the event, which will take place at the Five venue in Farnborough on 10-11 February, application engineers will be on hand to provide consultations, technical expertise and application know-how for power design needs.

On display on Stand C37 will be the new LD Series of light-emitting-diode (LED) power supplies. Developed for both indoor and outdoor LED lighting applications that require a robust design and a long design life, TDK-Lambda's LD Series is IP66 rated and accepts a wide universal AC input. The first products in the range are rated at 12W; the LDV12 Series provides a constant voltage of 12V, 15V and 24V and the LDC12 Series offers constant currents of 350mA and 700mA.

The company's IPS Series of IP67-rated single-output power supplies is available in 50W, 75W and 100W nominal ratings. These units are designed to power equipment in hazardous and hostile industrial environments. Certified to ATEX Directive 94/9/EC and IEC60079-0, -15 standards, these power supplies are suitable for Protection Class II 2G Ex mb T4 environments for end equipment where a potentially explosive atmosphere is occasionally present.

Other demanding applications include in-machine and factory-floor installations, wash-down environments and more robust outdoor applications such as motorway matrix signs and renewable-energy control circuits. TDK-Lambda's Custom Power Solutions brochure profiles the company's custom power solutions and capabilities across the Europe, Middle East and Africa (EMEA) region, ranging from full bespoke designs, modified standards and brick-on-board products.

TDK-Lambda Converters Address Railway Applications

TDK-Lambda has expanded its DC-DC converter line with the introduction of the CN-A Series that has a wide 60-160V DC input range, which is widely used in railway applications. Available with nominal output voltages from 5V to 24V (adjustable +/-10 per cent) and power ratings up to 100W, these wide input range isolated power supplies are fully-regulated.

The CN-A DC-DC modules are suitable for both rolling stock and fixed installations, enabling customers to design cost-effective EN50155 compliant systems without the risks associated with custom product designs and in a much shorter timescale. TDK-Lambda also offers a design and manufacture service for customers preferring to buy in complete systems meeting exact electrical and mechanical requirements. Designed for harsh environments, the CN-A Series meets the stringent shock and vibration requirements of IEC61373 Category 1 Class B, as well as the Japanese equivalent standard JIS E 4031.

In addition, all models accept the wide-range DC input commonly found in railway applications, which allows operation from any voltage between 60 and 160V. These baseplate-cooled power supplies, with industry-standard quarter-brick pinout, provide high, true useable power from -40 to +100C, without derating. The CN100A110-24 model, for example, offers up to 88 per cent power conversion efficiency, 60.5W/in3 power density and delivers up to 4.2A useable output current in a package measuring 57.9mm (L) x 36.8mm (W) x 12.7mm (H).

As standard, they are equipped with remote sense, remote on/off and input-to-output isolation of 3,000V AC, as well as overvoltage and overcurrent protection circuitry. All CN-A models are delivered with TDK-Lambda's five-year warranty, are safety approved to UL/CSA/EN60950-1 and carry the CE mark, according to the LV Directive.
