Advertorials 20W Brick DC-DC Converter designed for Railways

offers input range from 8.5V - 160V Components Bureau are pleased to announce the new DC/DC converters AER20-W and AER20-DW from AUTRONIC. The compact 20 W power supply is designed for harsh applications and suitable for the railway with an input range of 18:1. The new edition of the AER series are galvanically isolated DC-DC converters with 20 W power in a sealed housing. The 2”x1” bricks have been specifically designed as reliable solutions for applications such as railway systems, battery powered equipment, measuring instruments, displays and many other applications with harsh requirements. The unique key feature is the input range from 8.5 V up to 160 V in a

single device. This allows the nominal input range of 12...110 V including tolerances (-30 % and + 45 %) to be covered with only one device and facilitates the design-in of the power supply. The AER20-W offers high efficiency up to 88 % with the option of heat sink, ensuring even better heat dissipation for higher thermal requirements. The small power supplies are designed for use in the temperature range from -40°C to 85°C (case up to 105°C). With natural convection, the converter can be operated up to 67 °C without derating. The voltage converters have many protective functions integrated, such as protection against overcurrent, overvoltage and the DC/DC converters are also short-circuit-proof and have a low no-load current consumption. The power supply can be controlled via remote ON/OFF. Further features are a high I/O isolation with 3000 Vac with reinforced isolation. The AER-20W meets the environmental requirements of shock/vibration according to EN 61373 category 1 class B, dry and wet heat according to EN 60068-2-1, 2, 30 and the EMC standard EN 50121-3-2 for rail vehicles(with external filtering components), as well as the railway standard EN 50155. Fire tests according to EN45545-2 have been performed successfully. Versions for the nominal railway voltages of 24...110 are available. In addition, the converter can be used for 12 V applications, as the converter can be operated up to 8.5 V permanently.

Security & switch solutions from Foremost

Electronics Foremost Electronics, the engineering-led Essex based importer and specialist distributor of electromechanical components offers a wide range of Security solutions for electrical and industrial equipment installations & security systems and also announces the availability of the new E18 mechanical incremental encoder from ELMA Electronic.

The industry standard footprint E18 product family incorporates all of the features

required for the widest range of applications while providing improved performance and manufacturability. Available with an optional centre push button with the choice of 3N or 6N push force and may be further customised with bespoke shaft dimensions and shapes, user specified detent torque and IP60 or IP68 front panel sealing for rugged applications. The Foremost range of USB connected IP Joysticks are cost effective and simple to use.

Encapsulated AC-DC converters provide

up to 36W and protect to IP67 Powersolve Electronics Ltd, specialists in power supplies for the widest range of applications for over 30 years, announces three new series of plastic encapsulated AC-DC converters that offer protection to IP67. These are therefore suitable for use where the ingress of moisture, oil and dust need to be avoided. The PS12MK (10-12 Watts), PS20MK (15-20 Watts) and PS36MK (25-36 Watts) are

ACDC switch mode power supplies that operate from a wide universal input range of 90 to 264VAC, 50/60Hz. Output voltages of 5V, 9V, 12V, 15V and 24V DC are available for each model range or in fact any voltage between 5V and 24V could be supplied if quantities make it viable.

The power supplies are housed in robust plastic encapsulated enclosures rated to

IP67 and they can be either chassis or wall mounted. Input and outputs are via 500mm flying leads as standard. However these can be other lengths and terminated with any connector required to suit the customers’ specific application if required. All models feature over voltage, over current and short circuit protection. Operating temperature range is -10 to +40 degrees C and humidity 10 to 90% RH non-condensing. Standby power consumption is ≤0.3 Watts max with no output load connected.

Input is Class II safety with 3000VAC input to output isolation. All models meet all relevant EMC requirements and TUV safety approvals.

These products are very compact with the PS12MK unit measuring only 56 x 39 x

26mm, the PS20MK 64 x 47 x 28mm and the PS36MK unit 133 x 50 x 34mm. The PS MK Series are ideal for a variety of applications such as LED lighting, CCTV cameras or any other low power electronic equipment requiring a power supply for harsh environments. Pricing is very competitive and full details of these and similar products can be found on our website:
