12V Battery Charger for Current Limiting Lead Acid SLA (WET, MF, AGM and JEL). The battery charging circuit SLA uses a two-step process to charge the batteries. It automatically switches to float charge mode at a constant voltage after current-limited fast charging. Float charge: slow charge, floating charge, buffer charge etc. known as. Thanks to…
@Kapibara shared the battery desulfator circuit for battery resuscitation, recovery of the dead battery, I made a similar desulfator circuit for battery repair and tested for a long time. NE555 integrated desulfator circuit warranty circuit kits have been tested by many people, but I did not want to deal with the double coil, I applied…
I will give information about how the HC-SR501 PIR motion sensor module works, HC-SR501 Features and its use with LDR. The HC-SR501 PIR sensor module can be used not only for security, but also for most automatically activated lighting systems, industrial automation, control areas. A few months ago, I used one of the batteries that…
Actually, I implemented the power supply circuit with limited possibilities, but it is sufficient for me, the first tests were done successfully. Since I have a toroidal transformer with an estimated voltage of 250W…300W 2X15VAC, I did the tests with it, and the normal sheet transformer can also have a usable power of at least…
I shared many SMPS circuits made with IR2153. IR2153 is especially suitable for use in amplifier power supplies, even in power amplifiers in large companies, in mixers Power supply uses IR2153 on the SMPS floor. (Yamaha EMX5000 mixer service manual ir2153) I have been working on the SMPS circuit I have applied for a long…
A simple 0-30V 0-3A regulated power supply circuit based on the NE5532 opamp IC that you can use in your electronics workshop. Basic parameters of the power supply: Input voltage 24 – 26 V AC, DC output voltage 0 to 30V, Output current 10mA – 3A. It’s an open circuit. The current limiting resistor is…
Compared to the previously shared Li-Ion battery balancer battery balance circuits, it is a simple circuit that you can make with less material. Li-Ion battery stabilizer is a system that controls the voltage of each cell/cell section and does not allow the charging voltage to be exceeded. If one of the cells is charged earlier,…
Every electronic system, even the simplest, requires a power supply. The presented board contains three stabilizers supplying voltage through pin connectors and special wires to the contact plate with pocket dimensions and 170 fields. Such boards allow you to build electrical circuits without the use of a soldering iron and tin. This pocket-sized kit will…
I have seen different versions of the power supply, even the same circuit has a halide designed as a battery charging circuit in the LM317 datasheet file and in some electronic books, but I did not have the opportunity to apply it. Nevertheless, the familiar power supply circuit such as the LM317, made with the…
The 0.2V-80V switched power supply built on TL494 Integration can be used in various devices, motors, battery, battery charging processes, etc. designed for. There is additional SMPS circuit with TNY267 integrated circuit for feeding elements such as TL494, Fan, Relay. Like many circuit elements used in the SMPS Project, this material was supplied from PC…
