170 kHz. The regulator has protection circuits for periodic current-proof, overcurrent-proof, undervoltage-proof and programmable soft-start. (View) MAX714/715/716 refers to the power supply system powered by cell piles. It has a micro-processor for detection. This system consists of a four-loop logic-controlled +5-V regulator and a three-loop switched regulator, a fixed positive output single-loop(+12V or +15V), a software-controlled negative output single-loop and a fixed negative single-loop. Its static current is 20A. This system has a spare cell piles switch, a low voltage warner and it can restart if the cell lapses. (View) Step-down Vary Power Circuit Composed ofMC34063 is shown in the diagram. MC34063 is a type of switching modehighly active DC/DC Changed circuits. Its internalincludes reference voltage source withthe function of temperature compensation, comparator, duty ration controllable oscillator with limited current circuit, driver and heavy current output switch tube. The +25V/+5V step-down vary power composed of it is shown in the picture, the features are: (VIN=25V when IO=500mA) line regulation is 12mV ±0. 12%; load regulation is 3mV ±0. 03%; ripple voltage is 120mV. If one-level filter (shown in figure) output ripple reduced to 40mV; conversion efficiency is 82%; short-circuit limiting current is 1. 1A. (View) EPC-755A photoelectric encoder has good performance and has good anti-interference in angle...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
