it is mainly used to vary the applied voltage as per our requirement.it is also called as dimmer stat
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
Older types of dimmer switches used a small transformer in them for a control power supply. Change this unit out for a new one as the technology has come a long way in the past few years.
Dimmerstat is the device with ac input an ac output. it consist of a variable transformer inside it so as to vary the output.
Yes. It depends on the fixture. If the bulb runs at line voltage (i.e. without a transformer), then yes. If it's a low voltage halogen bulb, such as a 12 volt running off of a transformer, then you'll need to find out if the transformer is dimmable.
no i think the same amount of power is needed to push through the variable resistor in the dimmer switch coil.
Although a dimmer can be designed for 12 v halogen lamps it is more common for dimmers to work on higher voltages. Dimmers have to work into a resistive load so it is not usually possible to place the dimmer on the high-voltage side of the 12 v transformer that comes with the lights.
In most cases, it is possible to install a dimmer switch or rheostat on a halogen light fixture. However, it is important to ensure that the dimmer is compatible with the specific type of halogen bulbs being used. Some halogen bulbs require a specific type of dimmer switch, so it is advisable to consult with the manufacturer or an electrician to ensure compatibility and safety.
Dimmer stat is an auto transformer which is generally connected to supply which provide us step up /step down output depending on the terminal to which input is connected. Normally there are two ways to operate a Dimmer stat:- 1.the output voltage can be varied from 0 to full supply voltage. 2. voltage from 0 to 12 % higher than supply voltage This can be easily understood by connection diagram of a Dimmer stat-
Halogen lamps should not be dimmed. At lower voltages the halide is not hot enough and will condense on the glass bulb, darkening it. You will be replacing bulbs all the time.
Look on the carton that the dimmer comes in. On the label there will be a list of lamp types that the dimmer can be used on along with the maximum wattage that the dimmer can control.
Regular Dimmer will work.
