LCD Monitor SMPS Circuit
This power supply functions with a broad input voltage range from 90 to 265 V AC and produces a dual output in the form of 5 V / 2.5 A, and 14.5 V / 1 A. The Circuit Layout The great aspect of this source is its minimal power consumption, optimized power consumption in idle […]
Temperature to Voltage Converter Circuit
In this post I have explained a simple temperature to voltage converter circuit using IC LM317. The idea was requested by one of the dedicated members of this blog. Technical Specifications I have eurotherm TS200A temperature controller.this is thyrister based. This required 0-5V control voltage. I want one temperature control circuit when temperature is 25deg […]
Temperature Triggered DC Fan Speed Controller
This fan speed controller works by sensing the temperature of the engine and is accordingly used for the triggering. As the temperature increases so does the speed of the fan motor and vice versa. Circuit Operation Operation of the proposed temperature controlled fan may be understood as follows: The speed of the DC motor alters […]
