Ce pointeur laser vert 30000mW 532nm est l’un des le plus puissant et lumineux vert pointeur laser, nous avons maintenant, il est conçu avec un objectif focusable, corps en alliage d'aluminium.
Pour le travail de fin d'année ou dans le monde professionnel, nous pourrions avoir besoin de présentations PowerPoint (ou autres). Et c'est toujours le jour de la présentation qu'on se rend compte qu'il nous manque un pointeur laser (la seule distraction pour le public). Il existe de nombreux modèles et les prix peuvent également varier. Ici, nous allons décrire un pointeur laser avec télécommande pour déplacer les diapositives d'une présentation.

[Spam Filter]Solar or Wind Powered Water Pump with electronic controller, screw type, sold as a package with controller. Each system consists of a 370 Watt pump, pump motor and a controller. This modular concept keeps all electronics above ground providing, simple servicing, ease of access and a low cost of ownership.  Motor is oil lubricated.  DC-powered, works as a solar-direct system, from a battery bank, or in conjunction with AC power conversion.Connects to solar electric or wind turbine power supply. Pump adapts to varying power input by tracking most efficient operating point, or Maximum Power Point Tracking (MPPT).  A versatile and high quality pump, these pumps can run from not only solar and wind, but also from the grid through a rectifier, a generator, a battery or any combination of these sources. Efficiency is higher when voltage input is higher, but the pump will operate on a wide range of direct current voltage inputs. No grid power needed, off-grid solar water systemPump electronics designed to run with variable power inputPump can "soft start" with little sun or wind due to capacitorsMaximum Power Point (MPPT) tracking adapts to varying powerLightning protectionSelf PrimingStainless steel parts for longer lifeNon-sensor shielding motorMotor efficiency over 90%.Fully automatic operationRemote operation safeguardsBuilt-in Protection against overloading and overheatingAutomatic restart when water returns to the well or when the motor temperature returns to the safety rangeContinuous load condition and voltage monitoringPrice includes pump and controller.
