🔌 Softstarter: benefits scheme, step by step guide

Low-end models are equipped with a rare power supply soft start (BPP), through which a drill or Bulgarian It operates without jerks and less wear. You can buy a button and set its own, but it would require revision tool. In addition, because you lose the right to warranty repairs. The output of this situation is to modernize conventional extender. From this review of the online magazine HouseChief.ru edition, you will learn how to modify the standard elektroperenosku to included with the tool it worked smoothly.

Power tool that enables smooth start

Before you upgrade the power and portability to equip its soft-start unit, you need to consider the benefits of this alteration. Thus, the advantages of introduction devices.

1. The lack of current jump when you turn on power, which prevents overload of home network.
2. Less wear of mechanical parts of the tool.
3. Less often fail rotor and stator windings.
4. Less fade elektroschotki.
5. No sparking on the collector of the armature and burn its slats.
6. When the drill is started or Bulgarian do not break out of hand, it is necessary from the point of view of safety.

Carrying a soft start on the base unit KRRQD12A

One of the options carry with BPP to connect power - the use of electronic KRRQD12A block. need for modernization:

• directly the electronic unit;
• extension cable (serial or homemade);
• soldering Iron solder;
• power socket for external mounting;
• PVA piece of wire 3 × 2,5;
• knife;
• duct tape or shrinking;
• a piece plywood or boards.

Process of modernization extender

Picture	Process description
	To begin to understand Electroextension and do in the body opening for the new wireWhich will be connected to the outlet surface mounting. We clean PVA 3 × 2,5 on both ends.
	Solder the wires to the contact terminals carrying.
	Fix an extension lead with the help of the board screws and close its protective cover.
	We pass a piece of wire into the housing surface-mounted sockets and fix it on the board. We clean the ends of the wire.
	Wiring diagram.
	Plug KRRQD12A smooth start on is shown in the previous photo scheme. Junctions propaivaem and dress or use heat shrink insulation tape.
	PPO insert and contact terminals in the socket housing.
	Close the socket cover and check the operation of the modernized transportation.

Carrying with PPO with speed regulation

Please find another embodiment carrying makeshift with PPO and speed controller. The diagram below allows the power tool to provide a smooth ride, and exit at the rated speed. Acceleration time to the stated rate depends directly on the used capacity capacitor C3. To adjust the speed used variable resistor R2 group A.

You can set the unit a smooth descent directly into the tool handle, but it is more complex modernization and, as already mentioned, it can lead to deprivation of the right to a warranty repair. The optimal option to collect a block of smooth start to the speed controller - is to use the splitter boxes. In this scheme, the triac used TS122-25-5, but can be set to virtually any device class voltage not less than the fourth current and nominal values ​​not lower than 1.5-2.

The simplest scheme soft starter unit for use in a drill collar

soft start unit with speed controller for power, made on the basis of the thyristor KU202, is popular because of its simplicity of execution. To create it and the connection will not require special skills, and components can be purchased at any store radios and on the market. BPP consists of a diode bridge, a variable resistor for voltage control and thyristor circuit configuration.

Due to the fact that the implementation of this scheme BPP requires a small number of parts, and its size fairly compact, it can be integrated in the tool handle and in the outlet housing extender. The operating principle of soft starter unit is to adjust the power of the rotor speed by power limitation in the manual mode. This scheme is designed for use with the power capacity of 1.5 kW. BPP to work with a more powerful tool is required to replace the thyristor with a more powerful device. It is necessary to take into account the fact that the control scheme is different from the original.

A few words in conclusion

As you can see, the soft starter unit is very important for the equipment, and make it pretty easy. It allows you to significantly extend the life of the drills, Bulgarian and the like equipment, to facilitate the work with them and to protect you from injury. The review presents the most simple and affordable soft-start circuit blocks that you can do yourself, and quickly. If you have other effective schemes, then share them with us and our readers.
