- | 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 have to be considered for the selection of the power supply: | ||
- | |||
- | * The peak voltage of the power supply must be less than 16 V (absolute maximum: 18 V) and the minimum voltage must be at least 4.5V. Any power supply within that range 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 usually have voltage regulators. (Take care for the correct polarization: | ||
- | * Power supplies from unused consumer electronics, | ||
