This is a project of Simple 12 Volt Charger Circuit Diagram with LM350.The strength supply routine structure is developed as a resource of continuous present with adverse heat range coefficient. Transistor Q1 (BD 140) is used as a heat range indicator. transistor Q2 is used to avoid the strength supply from discharging through R1 when strength is out of stock. Getting routine is developed depending on the LM350 present regulator IC. The result present of the battery charger can be altered between 13-15 V by various the POT R6.  Simple 12 Volt Charger Circuit Diagram with LM350 LM350 will try to keep the present decrease between the feedback pin and result pin at a continuous value of 1.25V. So there will be a continuous present circulation through resistor R1. Q1 act here as a heat range indicator with the help of R6/R3/R4 elements that are more or less manages the platform present of Q1. As relationship emitter / platform of transistor Q1, the same as other semiconductors, contai...

S0 = ‘OFF’ Push button S1 = ‘ON’ Push button K1 = Line contactor K2 = Star contactor K3 = Delta contactor K4 = Star delta timer (7PU60 20) F2 = Overload relay F1 = Backup fuse F3 = Control circuit fuse This is a starting method that reduces the starting current and starting torque. The device normally consists of three contactors, an overload relay and a timer for setting the time in the star-position (starting position). The motor must be delta connected during a normal run, in order to be able to use this starting method. The received starting current is about 30 % of the starting current during direct on line start and the starting torque is reduced to about 25 % of the torque available at a D.O.L start. This starting method only works when the application is light loaded during the start. If the motor is too heavily loaded, there will not be enough torque to accelerate the motor up to speed before switching over to the delta position. When starting up pumps and fans for example, th...

TV tuner that is used on older models and new models of television there are some differences. Therefore, understanding the different types of tuner would be useful if we want to replace the tuner with the other models. Supply voltage tuner. Tuner older models generally use a supply voltage of 12v, the new models are commonly used 5V supply voltage. Some use a 9V voltage, but very rare. TV TUNER Voltage Synthesizer tuner (VS tuner) Tuner that uses a tuning control (VT or BT) with a voltage between 0 to 33V Voltage Synthesizer tuner named. TV can be found on the aircraft models, old and new Based on how the control band-switch, Tuner VS then there are 2 kinds, namely Using 3-Band input sw, the VL-VH-U Using 2-Band input sw, the Band SW1 and SW2 Band. This tuner is actually similar to the type of band 3-sw. For control-sw 2 band is in the tuner will still be converted into 3-sw bands. Frequency Synthesizer tuner (FS tuner) or the type of PLL Tuner wherein the tuning voltage and the vo...

Already Know about the transistor above? transistor above is one of the transistors that are applied at the amplifier end audio amplifiers. Because the power output and good quality of this transistor is very popular with high-power amplifier makers. Transistors on no other than is 2SC2922 and 2SA1216, transistor pair is already very well known as a reliable amplifier. With a price not too expensive and not too large transistor large is also very suitable. And this transistor has its own code for its quality, its code is like 5DY, 57P, 85Y, 92P, etc.. to see datsheet transistor can be seen below. Maximum Voltage  180V maximum collector current  17A Total power output  200W To more clearly and accurately datasheet can be found here.

Counters in PLC | Types of PLC Counter   Counters count rung transitions.   The CTU runs the accumulated value of the counter up on the false to true rung transition, and the CTD instruction runs the accumulated value down.   The CTU and CTD can be used in conjunction with each other. Counters consist of the following components: ACC Accumulated Value PRE Preset Value CD Count Down Bit CU Count Up bit OV Overflow Bit UN Underflow bit By default, data file C5 stores counters, however, other counter files can be added as well. Below is how the C5 Data file would appear: For the CTU instruction:   The CU bit is high when the CTU instruction is true.   The ACC value increments by the value of 1 each time the CU bit goes high.   When the ACC   reaches the PRE, the DN bit will be set.   The CTU will continue to increment the   accumulated value until it reaches the maximum possible value for a 16 bit signed integer   (32767).   If the ...

Here is Easy Build Automotive Electronic Project of motorbike alarm. Alarm can be fitted in bikes to protect them from being stolen. The tiny circuit can be hidden anywhere, without any complicated wiring. Virtually, it suits all bikes as long as they have a battery. It doesn't drain out the battery though as the standby current is zero. The hidden switch S1 can be a small push-to-on switch, or a reed switch with magnet, or any other similar simple arrangement. The circuit is designed around a couple of low-voltage MOSFETs configured as monostable timers. Motorbike key S2 is an ignition switch, while switch S3 is a tilt switch. Motorbike key S2 provides power supply to the gate of MOSFET T2, when turned on. When you turn ignition off using key S2, you have approximately 15 seconds to get off the bike; this function is performed by resistor R6 to discharge capacitor C3. Thereafter, if anyone attempts to get on the bike or move it, the alarm sounds for approximately15 seconds and als...

42 Fundamental Laws of PLC Programming  Dear friends cant stop sharing this with you. The 42 fundamental laws of PLC ,   a programmer must know this . Courtesy of the Members of MRPLC.COM   PLC LAW PLC LAW 1 - don't over complicate the simple.  PLC LAW 2 - make sure you plug the cable in before you try to figure out why you can't go online.  PLC LAW 3 - during startup, always verify i/o before testing the program  PLC LAW 4 - when connecting your laptop to the plc, don't tighten the screws on the serial cable at the laptop side.  PLC LAW 5 - read the manual before trying to install/commission an unfamiliar piece of hardware.  PLC LAW 6 - always have all possible backup files (plus read from plc etc.) Before starting any changes...  PLC LAW 7 - always double check you have the right cables for your CPU type and backup install software with you before you step on the plane.  PLC LAW 7.1 - when working in a lan or wan environment al...
