PRODUCTS EDITOR’S CHOICE DC LOAD SOLVES POINT-OF-LOAD CONVERTER TEST CHALLENGES I


ntepro Systems has developed a high-speed electronic DC load,


which joins its family of power system automatic test equipment (ATE). The EL 2000 HS Series is a


stand-alone 40W load module providing point-of-load (POL) connections and point-of-use


(POU) for fast slew rate DC loading. Ever-higher switching speeds and lower operating voltages present unique challenges in testing POL/POU power conversion systems. In response, this solution offers a smart on-board load head that minimises inductance, resistive losses and noise, which pose serious problems with loads using wires to connect the load to the device- under-test (DUT). In addition, the device is designed for sub-1V testing to meet the demands of low-voltage devices. The solution features a


standalone modular POU design, along with a smart on-board load head, that allows for positioning the load to DUT without the need


for customisation. The standard load offers four programmable modes of operation: constant current, constant resistance, constant power and constant voltage. All have a 50MHz measurement bandwidth with a 150MS/s, 14-bit digitiser. Measurements include voltage,


current, power, noise, settling time and overshoot/undershoot for both V and I. The standard 20V/20A/40W module can sink 20A with only 0.3V applied to the load head. In constant-current mode the


module achieves 40A/µs rise time with a 20A load for high-speed pulse loading when conducting real load simulation of high-bandwidth devices.

MAKING VEHICLES MORE ENERGY EFFICIENT


Power quality specialist REO UK has launched a water-cooled power resistor for braking systems in hybrid and electric vehicles. The design of the resistor allows excess energy generated during braking to be converted into heat and used in heating systems, increasing vehicle energy efficiency while reducing voltage transients. This makes it ideal for vehicles in agricultural, commercial, haulage and fleet applications. The REOHM BWD 330 operates at 800V


CREATIVE HUB SET-UP ONLINE TO HELP ELECTRONICS EDUCATION


RS Components has unveiled a new education hub to help schools, colleges and universities get involved with industrial electronics and other engineering equipment to support teaching and learning requirements, as well as to encourage creativity, design and innovation. The distributor is working closely with schools and universities to


provide a wide range of the most relevant and up to date products and technologies, in conjunction with maintenance products and support. The company also works very closely with suppliers to deliver the latest education offers, as well as educational versions of products, such as Tektronix digital oscilloscopes. Educational product versions are usually


the same as standard products but with additional features at no additional cost – for example, including multiple software licences and a full pack of features or accessories. A particularly suitable offering for educational establishments is the Tektronix TekSmartLab, a network-based


lab instrument management solution, which enables the quick set-up and efficient managing of basic electronics in engineering laboratories. This solution enables improved connectivity, workflow and automated systems. For example, lab managers can set-up configurations of multiple instruments with one click, and instructors can efficiently manage teaching workflow. In addition, students can retrieve and save test results wirelessly via smart devices, edit and submit test reports electronically and download materials from the lab server. The RS education hub centres on a wide range of solutions that have an industrial focus including robotics,


industrial automation and electronic engineering as well as mechanical-based applications including 3D printing, process automation and motion control to help aspiring engineers. www.rs-online.com


and provides continuous power between 15,000W and 60,000W depending on the model. It is resistant to temperatures from 40 to 1200


Celsius and is also capable of


functioning properly under shock and vibration levels up to 100G. It is ingress protected to IP69K, meaning the device is resistant to high pressure spray-downs and shows no harmful effects on performance. www.reo.co.uk


RS Components is now shipping the official Raspberry Pi 3 Starter Kit from the Raspberry Pi Foundation. This Starter Kit can be up and running by simply being plugged in with just a few cables to a TV or monitor, and turning it on. The kit includes the latest credit-card- sized Raspberry Pi single-board computer: the Raspberry Pi 3 Model B, delivers enhanced performance due to the powerful 64-bit ARM Cortex-A53 quad-core processor. It also includes wireless connectivity directly on the board to offer integrated Bluetooth and wireless LAN connectivity as standard IoT . www.rs-online.com


MULTI-POINT LASER SENSOR WITH SPEED AND PINPOINT ACCURACY TO A 1µmMEASUREMENT RESOLUTION


The HL-D3 series multi-point laser sensor from Panasonic offers measurement with optimal speed and pinpoint accuracy to a 1µm measurement resolution. The construction of the sensing element


allows for the selection of individual or various measuring points along the width of the sensors measurement range. This flexibility offers several advantages over conventional 2D laser measurement systems meaning an increase in processing speed and the ability to measure up to 10 individual points within the measurement range. This gives the user the ability to adjust the measurement intensity at individual points

where different materials make up the measurement area of a component. This allows stable sensing to be achieved over the whole measurement range and can eliminate the chance of saturated or insufficient light intensity affecting the measurement accuracy. Accompanying configuration and monitoring


software offers the ability to analyse the configuration of the sensor by displaying light intensity and displacement information in addition to calculating the values of height, width, cross sectional area and the individual MSDS point values. A 3D representation of the measured object can also be calculated. www.panasonic-electric-works.co.uk
