I present an overview of the popular SkyRC iMax B6 mini charging. The instruction is in English only. The device itself is wrapped in a soft bag. Cables included. A warning tag is pasted on the screen stating that if something went wrong - they are to blame, there was nothing left unattended :)

The initial version of firmware is V1.10. The firmware was updated on V1.12 - it added the ability to charge lithium without balancing, which can sometimes be useful, and sometimes dangerous. It was not possible to flash under Win8.1 - it was flashing under Wn7 with language switching to English. As it turned out later, it was necessary to run the program on behalf of the Administrator. Under WinXP, the program refused to start. How to work with this charge has been written many times in other reviews (links below) and it makes no sense to repeat it, inflating the review, so I will try to tell only new information ...

A photorelay is a useful automation device that allows you to automatically control the light depending on external lighting. The device arrived hermetically sealed in an antistatic.

The installation is excellent, the board is washed. Light sensor (photoresistor) on the connector, wire length 30cm Power supply 12V, current consumption when the relay is off - 3.75mA, when it is on - 36mA. There is protection against reverse polarity of the power supply (diode).

The power supply is indicated by a red LED, when the relay is activated, the blue LED lights up. A tuning resistor adjusts the sensitivity of the photo relay. When the illumination decreases below the threshold, the relay is activated. The sensitivity adjustment range is wide enough. The circuit is the simplest analog device on a dual comparator LM2903. Switching relay with changeover contact ...

The thermostat is a control device to maintain a certain temperature with a given accuracy. It can be useful in various automation systems (refrigerator, greenhouse, pipe heating, boiler, ventilation, cars, etc.).

The thermostat was ordered here with a reliable one, that this time they will send something way. I admit that I am skeptical of such devices - I'm used to working with serious multifunction devices, so I will be very critical.

Board dimensions: 50x40x16mm. The workmanship was pleasantly surprised, the board is almost washed, the installation is neat, all the details are in place. However, the design is inconvenient for embedding - the indicator and buttons are recessed in relation to the relay and connectors. In mind, they had to be placed on the back of the board. The setting range and temperature display is -50 ºС +110 ºС ...

For the possibility of constructing highly functional panels with exceptional flexibility in the design of automatic control and protection systems, modular relays for various purposes are used. They make it possible to create reliable and functional solutions for almost any object. Compliance with the standard (modularity) in terms of component sizes allows you to complement functions, combine in a new way, and improve an already installed system by adding, for example, new modules to a DIN rail. Consider what modular relays are, and what they are used for.

Impulse relays. When applying a short-term control pulse, the relay is activated by switching the power contact. This is a bistable relay that serves to control the on and off of electrical circuits from different places. A typical example of the use of such a relay ...

A contactor is an electric electromagnetic device that is designed for frequent switching of power circuits in normal conditions. The contactor is switched off and on remotely in manual mode or by applying a control pulse from other devices. Depending on the type, contactors can have from one to four poles of power contacts and can be used in circuits, both alternating and direct current. To extinguish the arc arising in the process of switching the load currents, arc chokes are provided in the design of the contactors.

Modular contactors are compact electrical devices that are designed to be mounted on a special DIN rail. The rated current of the modular contactors is up to 100 A, the rated voltage is up to 660 V.  The contactor is designed for switching currents in normal mode. That is, this electrical apparatus...

A very convenient tool for metering consumed electricity in everyday life is the household wattmeter, which is widely used recently in the market of measuring instruments. This device serves as a portable meter for energy consumption and associated material costs.

This is very convenient for planning energy costs, as well as for optimizing some household consumers. The device is a digital device, in appearance resembling an adapter or adapter, equipped with an indicator display and several control buttons.

The device measures and displays on the display the consumption parameters of household electrical appliances connected through it to the household electrical network. These parameters are: mains voltage, current drawn by the load, power factor of the load ...

The manufacture of stranded wires in its own technological process is much more complicated than the manufacture of stranded wires, and requires manufacturers of various cable and wire products significantly more labor and material costs. Accordingly, the cost of stranded wires is higher than stranded wires.

Why are stranded conductors needed? The main advantages that they have in comparison with mono-core ones are flexibility and reliability. Especially, the flexibility of a multicore cable is appreciated in switchboard production, where often in tight spaces it is required to mount a large number of wires with numerous bends and even weaves.

The reliability of a multicore cable lies in the fact that during the fracture of some cores, it continues to fulfill its functions, due to the remaining whole cores. A prerequisite for the flexibility of the wire ...

Thanks to the eloquent and sometimes intrusive advertising of LED lighting, the latter is confidently being introduced into our lives. That's right, we must keep up with progress. Only for the sake of this progress, often, one has to sacrifice the quality of light, its ability to transmit the true color of the illuminated material.

Somewhere this is permissible, and somewhere absolutely not. For example, in the field of professional lighting of goods in stores, fashion boutiques, etc. The “right” light will make the product more attractive and contribute to a faster purchase (especially if the competitors have antediluvian raster lamps behind the wall).

If we take into account the fact that young entrepreneurs are not ready to spend money on really high-quality, and therefore expensive LED lamps, and the specifics of the products require ...
