  • Solar Simulator for Concentrator Cells

    Optosolar GmbH

    Optosolar offers solar simulators with continuous light for small area solar cells (ca. 10mm x 10mm). depending on the cell size, the concentration ratio can exceed 1000 suns. Special designs cover low concentration on large area wafers (156mm x 156mm), as well as line focus applications (e.g. 8mm x 156mm at 8 suns). Flashlight Solar Simulators have the advantage of negligible temperature change to the solar cell. For this reason, they are often used for very high concentration ratios or for multijunction cells in a solar simulator with adjustable spectrum.

  • Rail Vacuum Circuit Breakers

    Omnicor

    Rail Vacuum Circuit Breakers are usually multi-functional AC vacuum circuit breakers combined with several other functions such as Disconnect Switches, Earthing Switches or Pantograph Interlocking valve making them a unique and small unit. Small size and light weight make vacuum circuit breakers perfect solution for rolling stock running on 15 kV or/and 25 kV railway networks. In addition to operating frequency of 50 Hz and 60 Hz sometimes 16.7 Hz frequency is also required. Because of rail vacuum circuit breaker location on the train and wide operating temperatures on the train routes temperature from -50 C to + 70 C is also one of the requirements.

  • SiC UV spectrometer

    SolGel Technologies GmbH

    World first: SiC-based UV spectrometerDue to the high visible blindness of the SiC material, precise UV spectrometry is now possible in the presence of strong visible radiation (no VIS scattered light effects).The high radiation hardness of SiC and its low dark current create an increased dynamic range compared to Si spectrometers.The first model in the new series is the UV line SiC128 (128 pixels, 220nm - 360nm). Variants with lower bandwidth and higher resolution are available.Other models with a smaller size and higher resolution are in co-development with our R & D partner, the Berlin-based Ferdinand Braun Institute.

  • Laser Distance Meters

    Zhuhai Measure Science and Technology Co. Ltd

    Laser Distance Meter is a hand tool to get the range for 2 points. A Laser Distance Meter sends a pulse of laser light to the target and measures the time it takes for the reflection to return.

  • 2 A Step Down DC - DC Switching Regulator

    STEVAL-ISA198V1 - STMicroelectronics

    The STEVAL-ISA198V1 product evaluation board is a step-down switching power supply based on the L7987L regulator in an HTSSOP16 package. The output voltage can be set starting from 0.8 V. Low drop-out operation, due to the advanced integrated switch management, can be achieved. The L7987L is a 61 V, 2 A step-down asynchronous switching regulator with embedded power MOSFET capable of delivering up to 2 A of current, depending on the application conditions. The embedded switch-over feature on the VBIAS pin and the light load management (pulse skipping) help maximize power conversion efficiency across the entire load range. The soft-start, current limit threshold and switching frequency are adjustable for application optimization. The device includes an internal 250 kHz oscillator that can be externally adjusted up to 1.5 MHz; two L7987L regulators can be synchronized in a 180° out-of-phase configuration for reduced total input RMS current.
