-This power supply is used to supply power, but also to charge and maintain the charged battery /*FIXME - opraveno na jednotné číslo*/. It can be operated, subject to the conditions described below, with all Unipi units and other selected Unipi equipment. In the event of a mains power failure, the power supply switches seamlessly to battery power mode. This achieves an uninterruptible power supply.+This power supply is used to supply power, but also to charge and maintain the charged battery.

-The **DRC-60A** power supply can be supplied with an input voltage of 110 / 230 V~. The power supply's output can achieve a maximum voltage of 13.8 V⎓ with a maximum current of 4.3 A. In combination with a suitable voltage regulator (DC/DC converter), it is ideal for powering all Unipi units from the Patron, Neuron, Axon, and Unipi 1.1 product lines /* FIXME - upraveno na product lines*/. The DRC-60A itself, without the converter, can be used to power Unipi Gate product line devices, as it can be powered with voltages in the 9–30 V⎓ range. For S-size units, the **DDR-15G-24** converter can be used. For M and L sizes, the **DDR-30G-24** should be used. Unipi 1.1 needs to be powered with 5 V⎓, so a suitable choice is e.g. **DDR-15G-5**.+The **DRC-60A** power supply can be supplied with an input voltage of 110 / 230 V~.

 ===== Useful tips ===== ===== Useful tips =====
-  * Before the input voltage is connected for the first time, the power supply output is disconnected even when the battery is /*FIXME - opraveno na jednotné číslo*/ connected and fully charged. Therefore, the input voltage must also be connected for full operation. When the input voltage is subsequently disconnected, e.g. power outage, the power supply output then switches seamlessly to battery power mode.+  * Before the input voltage is connected for the first time, the power supply output is disconnected even when the battery is connected and fully charged.
