Now the keyboard market mechanical keyboard plus RGB backlight has become a standard, domestic keyboard manufacturers in the low-end market is also more frequent replacement. Among them, the V700 mechanical keyboard of Cherry's original black shaft was made a deep impression on Raymond. So this time, Pythago launched the V700S alloy version for the first time. The greater the disappointment, the greater the expectation. The V700S can be understood as an upgrade of the V500 instead of an upgraded version of the V700. The current new product release has only the blue axis version, and the black axis and tea axis versions have not yet been sold. Compared to the V700, which was highly acclaimed at the time, the first impression of packaging was exclusively for Internet cafes, and the packaging was relatively simple (199). Sent a red little thing for the keycap, in addition, a simple specification is gone. As for the driver, you need to go to the official website to download, but I do not know if it is released before the new product, or other reasons, the current official website does not have a corresponding driver download, but also can not find V700S alloy version, I really doubt that I bought a fake product The USB interface is not gold-plated. The included keycap tool is still relatively easy to pull up. The keyboard is a 104-key non-conflict design (Say milk tea to the product is written 108 keys, this product can be deducted wages input), but although it is 104 key design, but also uses a high-key cap design, the appearance of the space seems to look Very abundant, but the actual use of the feeling is a bit hurried to space, early use, easy to misuse, I really regretted doing a little mouse (still should be in one step on board ah) The keyboard uses an alloy panel, black background, the edge of the entire panel cutting work is not bad, there is no flash, as for the anti-waterproof, the official did not give a clear statement, here do not try it! And everyone is concerned about the use of the axis, the visual test is Ray-Ban own axis, after all, 199 with Cherry original axis is not realistic. The keyboard backlight effect after the default is turned on, the brightness is not as high as imagined, although it can be adjusted, but it is adjusted to the maximum, it seems that there is not much change. The nameplate does not have a lighting effect, so we must give a bad review! Since there is no down to the driver, the lighting is borrowed from the official demo (the actual operation is different from the official demo, but the effect of the lamp is similar). This article uses the V700S to beat, the whole down, familiar with the layout of the keyboard, after the blind fight, it is still relatively smooth, but the layout for my big hand is still more pressing. The keyboard's banging is still relatively good, and the sound is crisp. However, at night, the sound is undoubtedly a little too loud. For the 199's mechanical keyboard, it is best to play with a light and enjoy the crisp pleasure of the mechanical keyboard. If you want to experience more gameplay or more refreshing mechanical pleasure, personal advice is still in one step! High Voltage Laboratory Power Supplies
The LTP series laboratory high-voltage power supply is a high-voltage power supply specially designed for high-voltage laboratory applications with high precision, high stability, and low ripple output characteristics. Built in 19 inches, 2U standard chassis with designed output power at 1KW and output voltage ranges 1KV to 60KV.

After optimizing the output stability and output ripple on the basis of the 1KW high-voltage power module, the stability and ripple of the high voltage lab power supplies can reach the level at 0.1%.
The high-voltage laboratory power supply is also a constant-voltage and constant-current type high-voltage power supply. The output voltage and current can be continuously adjusted from 0 to the rated value via the added control potentiometers added to the front panel, high resolution LEDs display for output KV and mA are also added for intuitive measuring of high voltage laboratory bench.
The lab high voltage power supply is also equipped with DB9 interface as standard. Customers can apply 0-10V signals and dry contact signals to the interface according to our interface definition to achieve comprehensive control and monitoring functions on the power supply, like high voltage start / stop, output setting and reading.
The LTP series laboratory high voltage power supply is equipped with complete protection functions, which can deal with sparking, short circuit, overload, load discharge and other situations.
At present, the high-voltage laboratory power supply is mainly used in Laboratory power, High-voltage test stands, Electrostatics, Capacitor / Insulations testing and Electrophoresis applications.
