No seguimento do curso de Automação, neste artigo apresento como perceber os conceitos básicos de programação de um CLP. No decorrer das próximas edições apresentaremos a forma de programar um controlador lógico programável Autores: Filipe Pereira - Eng. Elétrotécnico / Automação Klean Energie 4 Life, Ltda Energias Renováveis - Portugal As linguagens de programação são empregadas nos CLPs desde que estes surgiram em 1960. Estas permitem ao usuário inserir programas de controle utilizando sintaxes pré-estabelecidas. Previamente ao estudo dos três tipos de linguagem mais utilizados na programação de CLPs, convém rever alguns conceitos essenciais. O programa que vai definir o automatismo é constituído por uma série de instruções e funções onde são operados os bits de memória. Estas instruções e funções, serão introduzidas na memória do CLP, através de um periférico destinado a esse fim e que poderá ser uma console de programação ou software específico para PC.

The Mystery of USB Chargers

By  Jestine Yong  on July 9, 2014 Almost any new device such as mobile phone, tablet, iPod, GPS etc… will come with some sort of USB Charger and a cable. The cable will connect to your device through a dedicated connector, mini USB, micro USB or manufacturer’s specific.

Subwoofer Repair

By  Jestine Yong  on December 3, 2013   A customer brought this powered speaker for repair. It is a Wharfedale Titan 12’ subwoofer Amplifier. The complaint: No power. I opened the unit checking the usual things such as the fuse, EMI filter coils, voltage on filter caps etc. These all checked out fine, and I measured 320VDC over the two filter caps. The unit uses a SMPS. The smps and class-D Amplifier, are both on the same board. I then connected my analog meter to one of the secondary output lines going to the amplifier. There was no voltage here, and nothing on any of the other output lines going to the pre-amp board. I then proceeded to check if it is a shutdown problem, by switching the unit on and watching to see if the needle on my analog meter jumps up for a brief moment. No movement at all. This made me believe I have a primary –side fault. I checked the two, main switching Mosfets  and they were good. From the below photo you can ...
