Pulse Instruments
Two channels of 32 MHz clock drivers with up to 20 volt amplitude. The output voltage range is ±20 V, with independent high and low voltage settings. The inputs to the Card can be optically isolated. The card also contains voltage and current sense capability, which allows muxing of the current or voltage output measurements from all the Driver Channels in the system to a single DVM. The card allows independent programming of the rise and fall time of each channel one nanosecond increments.

TAND220A -
Amperis sl
The measuring instrument type TAND220A complies with the international standard IEC 61620. The instrument is based on the so-called "low-amplitude, low-frequency alternating current square wave method" and allows accurate measurements of conductivity and relative permittivity. Conductivity measurement in the range of 0.01 pS/m to 20,000 pS/m allows the use of this instrument for quality control of high resistivity liquids even at room temperature. The TAND220A works with a low test voltage and also with a low test current so that it does not represent a danger for the operators.

SCR ELEKTRONIKS
The test bench is specially built for low voltage- B, C & D curve MCBs. Specially designed custom built jigs are able to accommodate single, double, three and four pole MCBs. Decades of experience has helped us to design current source (transformer) in a special way such that good current regulation and high accuracy is ensured with a variable range without the use of any variable transformer in the system. The product is better than the competition with conventional technology at a lesser price!

RMO-A Series -
IBEKO Power AB
The RMO-A is a portable micro-ohmmeter designed for contact resistance measurements of switchgear during manufacturing, commissioning and maintenance stages. This micro-ohmmeter is widely used by medium and high-voltage circuit breakers manufacturers. Other typical applications are testing of disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. It accurately measures not only in factory environments but also in high-induction fields and substationsThe RMO-A series contains 6 models, rated from 100 A (RMO100A) to 600 A (RMO600A). The RMO500A (formerly CPM500) is our best seller, with 500 A ripple-free current and weighs only 8 kg.Although placed in a very portable and lightweight metal housing, RMO-A micro-ohmmeters have very high output power capabilities. They can generate 600 A test current continuously for up to 20 s. You can test with current up to 100 A without rest time. High output voltage enables a wider measurement range at the highest test currents, as well as the use of thinner/longer test cables. For testing with 100 A, 20 m test leads can be provided with only 16 mm2 cross-section.RMO-A micro-ohmmeter generates a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. During a test, the RMO-A ramps up with increasing current before measuring and decreasing current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.An additional option is a built-in High Precision module suitable for measurement of very low resistances, ranges from 1 to 30 µΩ, with 0,01 µΩ resolution.These instruments can store up to 500 measurements in internal memory. A built-in thermal printer is available as an option.Our free DV Win software communicates with the RMO-A micro-ohmmeters via USB or RS232 interface. It allows you to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.

TP121-TH -
Gigahertz-Optik GmbH
The photometric specifications of LEDs must meet very high tolerance requirements regardless of whether they are to be used in general, automotive or other specialist lighting applications. This is often a problem since the manufacturing tolerances of LEDs can be higher than those permitted in the end-use applications. Also, LED binning by LED manufacturers in order to classify LEDs based on their tolerances is performed with flash mode testing using pulsed current flow. However, end-use applications of the LEDs often operate in constant current mode and with significant thermal effects. The sophisticated LED processing industry therefore requires measurement devices that can be used for both manufacturer-compliant pulsed mode, as well as constant current operation mode. When the LEDs are run in constant current mode, the junction temperature has significant influence on the performance and lifetime of the LED. Therefore, test systems should be able to test the LEDs at specific junction temperatures.
