Skema Penyearah Tiga-fasa
Tuesday, September 21, 2010
The circuit Skema Elektro Lampu Emergency scheme is often called the light of this cas I've tried and this circuit can operate for eight hours depending on the batteries that we use but more effective if we use the dry batteries but the price is quite expensive and use the relay as an automatic switch so we do not have to bother because the circuit will automatically go on when the lights went out and and where electric lights, the circuit will automatically initiate the charge and the circuit is very suitable for the tasks of school if it is less obvious
what we need is • TRAFO = 5A CT /1
• TRANSISTOR =MJ2955/1
=BC 548 A/1
=BD 140/1
=L7812 CV/1
• RESISTOR =12 KΩ/1
= 10 KΩ/1
=82 KΩ/1
=1M Ω/1
=8K2 Ω/2
=3K9 Ω/1
=100 Ω/1
=4K7 Ω/1
• DIODA =MDA 2500/2
=IN4002/1
• DIODA ZENER =6V8/1
=5V6/1
For the S line, KWM-2 and KWS-1. Plug and play for the S line and easy install for the other radios.
Also available for Kenwood TS-520S/SE, Drake C line and several Hammarlund receivers.
Displays frequency with 10Hz resolution and displays operating mode (LSB, USB, AM and CW if you have the CW crystal installed in your radio).
Fully automatic. It measures the crystal osc. the PTO and the BFO and computes the carrier frequency.
Since it measures all the oscillators it takes into account any errors in the crystals in your radio.
Update rate of 5 times per second tracks real time while you tune.
Digital filtering to eliminate bouncing digits due to digital round off.
ie: does NOT bounce back and forth between 999 and 1000.
If all the inputs X, Y, Z are driven high, the diodes in series conduct, driving the transistor into saturation. Thus output out is Low.
what is Resistor Transistor Logic Diagram
In RTL (resistor transistor logic), all the logic are implemented using resistors and transistors. One basic thing about the transistor (NPN), is that HIGH at input causes output to be LOW (i.e. like a inverter). Below is the example of a few RTL logic circuits.
A basic circuit of an RTL NOR gate consists of two transistors Q1 and Q2, connected as shown in the figure above. When either input X or Y is driven HIGH, the corresponding transistor goes to saturation and output Z is pulled to LOW.
In DL (diode logic), all the logic is implemented using diodes and resistors. One basic thing about the diode, is that diode needs to be forward biased to conduct. Below is the example of a few DL logic circuits.Diode Logic Circuit
When no input is connected or driven, output Z is low, due to resistor R1. When high is applied to either X or Y, or both X and Y are driven high, the corresponding diode get forward biased and thus conducts. When any diode conducts, output Z goes high.
Points to PonderDiode Logic suffers from voltage degradation from one stage to the next.
Diode Logic only permits OR and AND functions.
Diode Logic is used extensively but not in integrated circuits.
