The article proposes a simple surge protector that will significantly reduce the likelihood of damage to household radio equipment from high-voltage impulse noise in the network. 230 B / 50 GC. The proposed power filter, by the level of protection they provide, In most cases, will be much more effective, what filters, embedded… Continue Reading
The article provides several options for constructing a voltage regulator, as straightened, and AC, for work with loads as with small (to 2 kW) power, and with loads of tens of kW. We offer our readers phase-rectified voltage (Fig.1)… Continue Reading
Charging one small capacity lithium polymer battery is not a problem, there are many simple schemes for this. Difficulty arises, when it is necessary to charge a battery with current, exceeding 1 BUT. With battery batteries, the situation is even more complicated. The presented device is ideal for such… Continue Reading
Presented module is an intermediary between the sensor devices and microcontrollers, operating from the mains supply, such as light bulbs and motors. It can help you realize the group and phase control, for resistive, and for inductive loads. This module will be useful, For example,… Continue Reading
acid batteries, in particular maintenance free version with an electrolyte in gel form, due to their relatively low cost and the operating conditions are still finding many uses in the buffer supply schemes. The described power supply circuit / Charger is designed to charge… Continue Reading
