SAFELY: The transformer will convert 120V AC household voltage to 12V AC safety voltage, built-in overload protector.There is an output terminal on the bottom of the back for connecting cables There have 2 hanging holes on the back for hanging the transformer. EASY TO OPERATE: Intuitive interface designed for easy use.CAMO DESIGN: Rainproof door is painted with camo pattern that protects the control panel from wind, rain and sun, while adding a touch of stylish scenery to your outdoor lighting system and it is very well put together with flowers and plants in your yard.6 VERSATILE MODES: TIMER(timed on/off), AUTO(dusk-to-dawn), 4/6/8/10 (turn on at dusk and turn off /4/6/8/10 hours later), PHOTO ON/ TIMED OFF(turn on at dusk, turn off at set time), ON, OFF.Goodsmann low voltage transformer are compatible with 12V low voltage landscpae lighting system and can be used with LED and halogen lights etc WIDELY APPLICABLE: Landscape transformer for your low voltage lighting needs.Learn about internal structure and working of potentiometer. When hand starting the timer, the unused start-line electric eye can be used as a split time eye. They are specified by their fixed value resistance. In case wiper is not used, it will offer fixed resistance across the two connections. Find Pathology Labs, Currency Counting Machine Dealers, Electrical Component Wholesalers, Phase Selector. If only one of the connections and wiper are used, it behaves as a variable resistor or rheostat. It consists of a fixed resistance track having connections at both ends and a sliding contact, called wiper, which moves along this track by turning the spindle. Potentiometer (Pot) is another class of variable resistors and is used as an adjustable voltage divider. The maximum voltage rating of the capacitors used must always be greater than the supply voltage. Click to learn more about working of a capacitor along with its internal structure. Since capacitors store charge, they must be carefully discharged before troubleshooting the circuits. Electrolytic capacitors are polarized while ceramic and paper capacitors are examples of non polarized capacitors. These are used to store energy like in a camera flash.Ĭapacitors may be non-polarized/polarized and fixed/variable. Other uses include, coupling the various stages of audio system, tuning in radio circuits etc. For this reason, capacitors are used for smoothing power supply variations. Of charging and discharging in AC circuits where the voltage and current across it depends on the RC time constant. The capacitor undergoes through a recursive cycle. Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals. The charge (q) stored in a capacitor is the product of its capacitance (C) value and the voltage (V) applied to it. Capacitor:Ĭapacitor is a passive component used to store charge. Read and learn about internal structure and working of a resistor. These special resistors are commonly used as sensors. Negative temperature coefficient (NTC), positive temperature coefficient (PTC) and light dependent resistor (LDR) are some such resistors. There are some non linear resistors also whose resistance changes with temperature or light. The resistance of a resistor can be estimated by their colour codes or can be measured by a multimeter. The low power resistors are comparatively smaller in size than high power resistors. Resistors can be either fixed or variable.
