- | All products are equipped with with a standard DC connector with 5.5mm outer diameter and 2.1mm center pin diameter. The center pin is the positive pole, the outer contact is negative pole. | ||
- | |||
- | The following rules should be considered for the selection of the power supply: | ||
- | |||
- | * Any power supply with minimum voltage of at least 4.5V and a peak voltage of less than 16V (absolute maximum: 18V) can be used. The current requirement depends from the product and the application. | ||
- | * If non-stabilized power supplies are used, it must be ensured that the peak idle voltage is within the valid range. | ||
- | * Stabilized power supplies are save if they are within the valid range. Switching supplies are always stabilized, stabilized transformer based supplies are usually labeled with " | ||
- | |||
- | Possible sources of supply are: | ||
- | |||
- | * From various shops in internet, e.g. from [[http:// | ||
- | * Universal power supplies with switchable output voltage from the supermarket or electronic stores. These supplies should be stabilized since they have to work with a wide range of consumer electronics. Make sure that you choose a proper voltage and the correct polarization (center pin: +, outer contact: -) | ||
- | * Power supplies from unused consumer electronics, | ||
