This is a digital isolation and termination circuit. This circuit uses The CLT3-4 that is a digital termination device with quadruple input. The CLT3-4 is designed for 24 V DC automation applications. The CLT3-4 drives an isolating opto-coupler and gives the front-end circuitry of a digital input module (I/O) in industrial automation. Here is the circuit: This circuit has a […]

This is a electronic ballast circuit using L6569. This circuit uses The L6569 because it can control a low voltage halogen lamp transformer or a symmetric half bridge inverter of a fluorescent lamp ballast directly. The prevention of cross conduction is done by Two 270mA buffers drive the inverter MOSFETs with a 1.25ms built-in dead time. This circuit need only […]
Read moreThis is capacitor replacement tutorial video. This video describes how to replace the damage capacitor with new capacitor. The capacitor has two important reading, they are capacitance and voltage. The capacitance shows how much energy that can hold that given voltage. The voltage reading shows the maximum voltage that capacitor can handle before it exploded. To replace the damage capacitor, […]
Read moreThis is a voltage divider video tutorial. This video explains about the voltage divider and the use of voltage divider. Voltage divider is the circuit that is used to reduce voltage using resistor. The voltage divider can be used in many things such as to create a point control voltage or generate reference voltage. The following equation defined the output […]
Read moreThis is a resistor color band tutorial video. This video shows how to calculate the value of resistor using color bands on the resistor. The Resistor has four color bands, the firs three bands show how many ohm the resistor can resisting, and the last bands is the tolerance. The first band is the first digit in how many ohm […]
Read moreThis is a testing capacitors video tutorial part 2. This Video shows how to check the leakage of the capacitors, the capacity of the capacitors and the breakdown voltage. In this video, to check the leakage of the capacitors, the capacity of the capacitors and the breakdown voltage by using capacitor and resistor analyzer. Just clip the capacitor with analyzer […]
Read moreThis is a tutorial video of testing capacitors part 1. This video shows how to check the capacitors especially for old capacitors. In this video, the capacitors is checked by using ohmeter. We can know that capacitor is good, dead, or has high leakage after testing the capacitors. The range of ohmmeter is set to maximum range. To check the […]
