" Precision Power Supply © 1986 Doug Bedrosian and 2010 Tony van Roon "This Precision Power Supply is a nice addition on your workbench as primary, or in my case, a supplementary power supply. With zero to 40V and 2A with adjustable current limiting it will surely gets lots of use on your bench. On average the most amperage for a power supply someone needs is around two or three amps. The sensitivity for current limiting is fully adjustable. Have fun building!" Introduction: Test instruments are considered to be some of the most useful tools available when constructing a project. They are also considered to be the most expensive tools one could buy. For instance, a power supply of any quality and usefulness can range from several hundred dollars to several thousand dollars. The alternative to buying a power supply is to build one. The power supply in this article has a voltage range from 0 to 40V and a current range from 0 to 2 amps with current limiting set by the user. The quality of the supply is determined by the time and care the builder takes while constructing it. How It Works: The power supply is best understood when divided into separate parts. The first parts to look at are the two power supply sections. The output supply section consists of XFMR1, Br1, C1, and C2. They supply the appropriate voltage and current required at the output. The IC supply consists of XFMR2, Br2, and C3. The two power supply sections must be separate from each other because a floating ground is required for IC1. The next section is the voltage control. RV1 and R2 determine the operating point of a constant current source out of pin 3 of IC1. By varying RV1 the maximum output voltage will be set. Pins 8 and 9 are inputs to a high gain differential amplifier contained in IC1. By adjusting potentiometer P1 the voltage at pin 8 will vary; this will cause the voltage at the output to change until it is equal to the voltage at pin 8. Due to the high gain of the differenti

"0-30 VDC STABILIZED POWER SUPPLY WITH CURRENT CONTROL 0.002-3 A 0-30 VDC STABİLİZE GÜÇ KAYNAĞI İLE AKIM KONTROL,002-3 A Orijinal görüntüsünü görmek için buraya tıklayın. 925x541 px. General Description This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30VDC. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 mA) to the maximum output of three amperes that the circuit can deliver. This feature makes this power supply indispensable in the experimenters laboratory as it is possible to limit the current to the typical maximum that a circuit under test may require, and power it up then, without any fear that it may be damaged if something goes wrong. There is also a visual indication that the current limiter is in operation so that you can see at a glance that your circuit is exceeding or not its preset limits. Technical Specifications - Characteristics Input Voltage: ................ 24 VAC Input Current: ................ 3 A (max) Output Voltage: ............. 0-30 V adjustable Output Current: ............. 2 mA-3 A adjustable Output Voltage Ripple: . 0.01 % maximum FEATURES - Reduced dimensions, easy construction, simple operation. - Output voltage easily adjustable. - Output current limiting with visual indication. - Complete protection of the supplied device against over loads and malfunction. How it Works To start with, there is a step-down mains transformer with a secondary winding rated at 24 V/3 A, which is connected across the input points of the circuit at pins 1 & 2. (the quality of the supplies output will be directly proportional to the quality of the transformer). The AC voltage of the transformers secondary winding is rectified by the bridge formed by the four diodes D1-D4. The DC voltage taken across the output of the bridge is smoothed by the filter formed by the

"A simple Remote tester to check all types of Remote hand sets……. This simple remote tester can be a good tool to check whether a remote hand set is working or not. It uses the commonly available IR sensor TSOP 1738.The IR sensor has a PIN photodiode and an FET signal amplifier enclosed in an Epoxy case. The sensor requires five volts for its operation and its output is active low. Normally its output gives + 5 volts and goes down to zero when it receives 38 KHz pulsed IR rays. When the remote handset is focused on to the sensor and any one button is pressed, buzzer beeps and LED blinks indicating that the handset is OK. Remote Tester Circuit Diagram "
