LÂMPADA TUBULAR LED

Cada vez mais as lâmpadas LEDs estão tomando conta da iluminação, para quem tem sistemas de lâmpadas fluorescentes tubulares é possível substituir por lâmpadas de Led tubular, das mesmas dimensões das originais, a única mudança é no circuito elétrico do soquete. Na adaptação é retirado o reator e substituído pela ligação direta na rede elétrica. Como você pode verificar,there are many,pt ...

What is a Grid-Tie Inverter

inversor grid tie

Este é um dos mais solicitados, I have received several emails asking for projects and electronic circuits Grid-Tie Inverters,pt, não são poucos os e-mails e basicamente são de usuários com pouco ou nenhum conhecimento em eletrônica. I always say that those starting out in electronics should start by simple circuits, as FM transmitters or a small fountain, since ...

Circuito de Chave seletora de Tensão Automática

Chave automatica Bivolt

Mesmo nos dias de hoje exitem muitos aparelhos elétricos e eletrônicos com chaves manuais de seleção de tensão CA. Isso é um inconveniente, principalmente para que tem que transportar uma máquina ou equipamento para diversos locais com diversas tensões. Com um sistema bivolt acaba com esse problema, mas se isso não é possível, colocamos um circuito que transforma nosso qualquer equipamento ...

Circuito de Proteção de Rede AC

Circuito protetor de Rede domiciliar CA

Infelizmente no Brasil estamos a merce de um serviço de energia elétrica domiciliar precário, onde não existe manutenção preventiva ou mesmo a modernização. Podemos dizer que estamos utilizando equipamentos do século passado, pois as empresas priorizam o lucro e não o fornecimento de energia adequado a população. As consequências deste descaso são muitas, entre elas, intermitências no fornecimento, mal contato durante ...

Dimmer circuit using MOSFETs

Dimmer usando Transistor Mosfet

We have seen here several circuits of dimmers, CC, CA, engines, for LEDs, Finally dimmers for almost all purposes. But this time we will introduce an electronic dimmer circuit that has very different characteristics of the other circuits. But this is special not because of using a Mosfet, they have already published a DC Light Dimmer using MOSFET ...

Grandesas Elétricas – Volts – Ampere – Ohms e Watts

Símbolos AC e DC

I'm starting to write an e-book in which I intend to teach basic electronics who is starting. I'll try to use simple language to try to achieve those users without affinity with the area. It will not be like any electronics course Senai, will not delve, but to give a basic understanding, enabling any user to understand a little electro-electronic, ...

Control for resistive load

controle para cargas resistivas

This controller for resistive loads is indicated for the control loads with power of up to 5 K Watts. According to the author this charge controller works perfectly and has been used to control a heating system water. A resistive load is a load that generates heat by applying a voltage. In other words, the resistive load converts the current into forms of ...

Electricity and the Human Body – Electrical Shock

ligação a terra

I decided to offer this article on Shock of another site that had electronic, he explains in great detail how it happens, how to prevent and first aid people suffering electric shocks. The electric shock is nothing more than the passage of an electric current through the human body, using it as a driver. This current flow ...

Electrical protective circuit for Bench

Circuito de proteção elétrica para Bancada

The bench or table is the kingdom of a technical, hobbyist or electronics student. A Work benches must have at least an antistatic rubber surface, a good grounding system and a power strip with fuse protection. In case of sensitive equipment, the ideal is to work with a personal grounding straps, and even a protection ...
