•

All electronic circuits need a power source to work.

•

For electronic circuits made up of transistors and/or ICs, this power source must be a DC voltage of a specific value.

Power Supply Characteristics •

The input is the 120 volt 60 Hz AC power line. Alternately, the input may be 240 volt AC.

•

The power supply converts the AC into DC and provides one or more DC output voltages.

Plan Training Session Lesson proper 2 INTRODUCTION •

A light dependant resistor (LDR) or a photo resistor or photocell is a light controlled variable resistor. Its resistance changes with the light intensity that falls on it.

A typical LDR •

Circuit symbol of LDR

They are made up of semiconductor materials having high resistance. WORKING OF LDR

A LDR works on the principle of photoconductivity. Photo conductivity is an optical phenomenon in which the materials conductivity reduces when light is absorbed by the material. CHARACTERISTICS OF LDR LDRs are light dependent devices whose resistance decreases when light falls on them and increases in the dark. When a light dependent resistor is kept in dark, its resistance is very high. This resistance is called as dark resistance. CONSTRUCTION OF LDR


Date Developed:


March 26,2015



Page 27

Plan Training Session Modern light dependent resistors are made of lead sulphide, lead selenide, indium antimonide and most commonly cadmium sulphide (CdS) and cadmium selenide. ADVANTAGES: LDRs are cheap and are readily available in many sizes and shapes. DISADVANTAGES: Highly inaccurate with a response time of about tens or hundreds of milliseconds. Light sensor: The LED lights up when the intensity of the light reaching the LDR resistor is sufficient. Example is Automatic Emergency Light: It senses darkness/night and turns ON automatically. Similarly it senses day light and turns OFF automatically. Series of LEDs are connected.


Date Developed:


March 26,2015



Page 28

Plan Training Session 2. Audio Compressor: Audio compressors are devices which reduce the gain of the audio amplifier when the amplitude of the signal is above a set value. This is done to amplify soft sounds while preventing the loud sounds from clipping. Some compressors use an LDR and a small lamp (LED) connected to the signal source to create changes in signal gain. 3. Fire Alarm: The alarm works by sensing the smoke produced during fire. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.7 V). The transistor will be OFF and nothing happens. When there is sufficient smoke to mask the light from falling on LDR, the LDR resistance increases and so do the voltage across it. The transistor will switch ON which is connected to a tone player to play music. 4. Automatic Street Light: It automatically switches ON when the night falls and turns OFF when the sun rises.

CIRCUIT OPERATION  is a simple water level alarm circuit that will produce an audible alarm when the water level reaches a preset level. 

The circuit can be powered of a (3 to 12V) battery and is very handy to use.

The circuit is based on an astable multivibrator wired around IC1 (NE 555).



The operating frequency of the astable multivibrator here will depend on capacitor C1, resistances R1, R2 and the resistance across the probes A&B.

Intelligent Wash System Sensors within the drum detect the size of the load and alter the water level and cycle time to correspond with it. This highly innovative feature saves time, money and energy. J Jetsystem The Zanussi Jetsystem automatically adjusts water level, cycle time and energy consumption to accommodate the size of the load. This allows you to wash smaller loads with minimal water and energy use. K L M Maximum Wash Capacity (kg)

The maximum amount of laundry (in weight) a machine can wash in one load. For example, a family sized machine may have a maximum capacity of 8 kilograms. Mini Load Setting Similar to the half load function. The amount of water and energy used by a cycle is reduced to accommodate a smaller amount of laundry. N Noise Level (db) The amount of noise in decibels (a unit for measuring sound) a washing machine makes whilst in use. The lower the number, the quieter the machine. Number of Programmes

The entrance to the washing machine drum by which you can load clothes. Pre Wash This function is used to rinse and lightly wash clothes prior to the main cycle. It is useful for stained and heavily soiled clothing. Q Quick Wash Cycle This programme completes a full wash in less time; it is energy saving and time-efficient. R Rinse Hold A very smart feature that allows you to delay the final rinse until a more convenient time.

Plan Training Session SpeedPerfect The SpeedPerfect function by Bosch allows you to reduce cycle times without compromising on the performance and quality of the wash. It is available on VarioPerfect machines. Spin Performance A rating awarded to machines which indicates how efficiently water is extracted from clothes during the spin cycle. Spin Speed (RPM) The speed at which the drum spins during a wash. A higher speed means clothes will be drier when they come out of the machine. Start Timer Delay This function allows you to load the drum, add your detergent and select a time for the machine to start up to 24 hours in advance. T U Unbalanced Load Control System Modern technology from Beko which ensures laundry is evenly distributed around the drum during the cycle. V Variable Spin Speed This feature allows you to choose the spin speed of a cycle. You can select a faster spin to extract more water and speed up the drying process, or slower speeds to reduce creasing. Variable Temperature The majority of machines now allow you to set the temperature of a cycle depending on your requirements. VarioPerfect
