This pack contains the LCR45 Passive Component Impedance Meter, great for advanced hobbyists and professionals. It also contains the very popular DCA Pro (model DCA75), fantastic for component identification, pinout identification, detailed characteristic measurement and curve tracing on a PC. Complete with USB cable and software on a USB flash drive. DCA75 Building on the continued success of Peak's existing component identification and analysis instruments, the DCA Pro brings an array of exciting new features for the hobbyist and professional alike. The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library. Automatic component type identification Automatic pinout identification (connect any way round) The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more. Components supported include: Transistors (including Darlingtons), Silicon and Germanium types. Measures gain, Vbe and leakage MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5 mA) and approx transconductance (for span of 3-5 mA) JFETs, including normally off SiC types. Measures pinch-off voltage (at 1 uA) and approx transconductance (for span of 3-5 mA) IGBTs (insulated gate bipolar transistors). Measures on-threshold (at 5 mA) Diodes and Diode networks LEDs and bicolour LEDs (2 lead and 3 lead types) Zener Diodes with measurement of zener voltage up to 9 V at 5 mA Voltage regulators (measures regulation voltage, drop-out voltage, quiescent current) Triacs and Thyristors that require less than 10 mA of gate current and holding current Stand-alone or with a PC The instrument can be used stand-alone or connected to a PC. Either way, the DCA Pro will automatically identify the component type, identify the pinout and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more. Curve Tracing When connected to a PC using the supplied USB cable, a range of low current curve-tracing functions can be performed. Various graph types are available, with more to follow: Bipolar transistor output characteristics, IC vs VCE Bipolar transistor gain characteristics, HFE vs VCE Bipolar transistor gain characteristics, HFE vs IC MOSFET and IGBT output function, ID vs VDS MOSFET and IGBT transfer function, ID vs VGS JFET output function, ID vs VDS JFET transfer function, ID vs VGS Voltage regulator, VOUT vs VIN Voltage regulator, IQ vs VIN. PN junction I/V curves, forward and reverse options (for Zener diodes) Curve tracing is performed using test parameters in the range of +/-12 V or +/-12 mA. All curve-tracing data can be instantly pasted into Excel for further graphing and analysis. PC Software is included with the DCA Pro on a Peak USB memory stick. Software designed for Windows 7 and higher (all 32 or 64 bit). LCR45 A great handheld LCR analyzer that can measure the value of your passive component (inductor, capacitor or resistor) and also measure the detailed impedance in a number of modes. The LCR45 offers enhanced measurement resolution (better than 0.1 uH!) whilst also giving you continuous fluid measurements. Additionally, the test frequencies of DC, 1 kHz, 15 kHz and 200 kHz can be set to automatic or manual modes. Supplied with removable gold plated hook probes, battery and user guide. Compatible with standard 2 mm test connectors. Not designed for in-circuit use. Automatic or manual component type selection: Inductor, Capacitor or Resistor Automatic or manual test frequency selection: DC, 1 kHz, 15 kHz and 200 kHz Inductance from 0.1 uH to 10 H Capacitance from 0.1 pF to 10,000 uF Resistance from 0.1 Ohm to 2 MOhm Inductance measurement also shows DC winding resistance Display of "Component type and values", "Complex Impedance", "Magnitude/Phase" and "Admittance" Test frequency displayed for all measurements Typical accuracy of 1.5% for inductors and capacitors (see spec table for details) Typical accuracy of 1% for resistors Test lead complete with gold plated 2 mm plugs and sockets Supplied with removable gold plated hook probes Included LCR45 DCA75 Extra GP23 Battery Extra AAA cell Dual Carry Case

As demand for solar panel installation has risen sharply, especially for installations larger than balcony power plants, the order books of solar companies are full. If you ask for a quote today, you may have to wait a while, if your request isn't simply postponed indefinitely. Another consequence of the solar boom is that some companies are charging very high prices for installations. Yet there is an obvious and radical solution to the problem of excessive prices: Do it yourself, as the English say. The price of materials is currently affordable, and it's the ideal time for those who do the work themselves. They couldn't save more. Add to this the satisfaction of doing something useful, both economically and ecologically, and the pleasure of building yourself. In this special issue, you'll find a wide selection of Elektor assemblies, from solar panel controllers to solar water heaters and solar panel orientation systems. The issue also contains practical information on solar panel installation and the technology behind them. Finally, there are a number of articles on the subject of balcony power plants, from how to install them to how to connect them to the Internet... Contents BASICS Dimensioning Photovoltaic Panel ArraysAn introduction to photovoltaic energy and the commonest techniques,followed by simplified calculation models and setup guidelines.
