Vigortronix AC/DC converters, available from Rapid Electronics, are claimed to be lighter, smaller, offer longer lifetimes and provide greater reliability than traditional transformers. The distinctive orange packaging emphasises the break with tradition.
Where DC voltage is required, the encapsulated switched mode power supply module can be used in place of a linear transformer. It has a built-in transformer and it also replaces the circuit components required to convert AC to DC – diodes, bridge rectifiers, capacitors, resistors and heatsinks. It occupies a considerably smaller footprint than a linear transformer, says the company and weighs just 20g in its lightest form.
Single Modules Available
It is available in 1-, 3-, 5- and 10W versions; the wide input range of 90 to 264V AC means that the 4pin modules are compatible with all international voltage ratings, says the company.
A single module can be ordered from the distributor.
Why Use an AC/DC Converter?
Alternating current (AC) is used for power line transmission and for high power devices like appliances and lights.
The characteristics of AC make it ideal for transmission over long lines and for delivering large amounts of power for relatively unregulated uses, such as generating heat and light.
Lower power appliances and devices require the closely regulated control of direct current power (DC). As a normal house is supplied with AC, it must be converted to DC for many uses.
