12-0-12 Transformer-500mA It is a 12-0-12 centre tapped step-down transformer, which means it can accept standard 220V AC mains voltage. The Transformer is one of the most important machines that literally transformed the entire Electrical Power Industry. It is an electrical machine that changes the voltage level with great efficiency, allowing power to be transferred over very long distances with little loss. A chassis mounting mains transformer with a voltage range of 12-0-12V and a current rating of 500mA. The transformer's primary winding is 230V, and the secondary winding is center-tapped. The transformer functions as a step-down transformer, converting 230V to 12V . It can be used in small rectifier circuits to charge a 12V battery, power small devices with low voltage ratings such as Arduino, PIC, AVR, Raspberry Pi, and other controllers, and charge mobile phones, among other things. Package Includes: 1 x 12-0-12 Transformer-500mA Specifications Input Voltage 230 VAC Output Voltage 12V, 12V or 0V Output Current 500mA

12V 1A Transformer - 1000mA The 12-0-12 1Amp Step-Down Transformer is a chassis mounting mains transformer. The transformer has a 230V primary winding and a secondary winding that is not center tapped. The transformer has insulated connecting leads with flying colors ( Approx. 100 mm long ). The transformer functions as a step down transformer, converting 230V AC to 12V AC.The transformer produces 12V and 0V outputs. The Transformer's construction is detailed below, including the Solid Core and Winding. The transformer is a static electrical device that transfers energy between its winding circuits via inductive coupling. A changing current in the primary winding causes a changing magnetic flux in the transformer's core and, as a result, a changing magnetic flux through the secondary winding. In the secondary winding, the varying magnetic flux induces a varying electromotive force (E.M.F.) or voltage. The cores of the transformer are made of high permeability silicon steel. The steel has many times the permeability of free space, and the core serves to greatly reduce the magnetizing current and confine the flux to a path that closely couples the winding.

Non-Invasive SCT-013 30A AC Sensor This is SCT-013-030 Non-invasive AC Current Sensor Clamp Sensor 30A. SCT-013-000 is a Non-Invasive AC current sensor i.e. it is a current transformer that can be used to measure AC current up to 100 amperes. This non-invasive current sensor clamped around the supply line can measure a load up to 30 Amps, and allow you to calculate how much current pass through it. It can be useful for building your own energy monitor or for building an over-current protection device for an AC load. This current clamp can be used to detect a current of up to 30A. Simply clip it around the current source that you wish to measure and it will produce a (very) small AC voltage proportional to the current. The cable is terminated on one end with a standard 3.5mm jack (like a headphone jack). Use this to build your own energy monitor and keep your power usage down, or use it to build an over-current protection device for an AC load. See the link below for an example project. Check out the datasheet for the pinout of the 3.5mm jack. Applications Suitable for the current measuring.
