-This power supply is used to supply power, but also to charge and maintain charged batteries. 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-60B** power supply can be supplied with an input voltage of 110 / 230 V~. The power supply's output can achieve a maximum voltage of 27.6 V⎓ with a maximum current of 2.15 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 line. The DRC-60B itself, without the converter, can be used to power Unipi Gate 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~. 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. 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 Unipi Edge and 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 power supply powers the connected load (Unipi unit) and simultaneously charges and maintains the batteries. The total output current of the power supply is up to 2.15 A, of which 0.75 A is reserved for charging the batteries and 1.4 A for the load at the output.+The power supply powers the connected load (Unipi unit) and simultaneously charges and maintains the battery.

-Switched on **Bat. Low** indicates that the battery is almost discharged. The remaining time depends on the state of the batteries and the connected load. This state is used to save the current values, set the safe state of the outputs, and other necessary tasks, e.g. sending a warning SMS message.+Switched on **Bat.

 ===== Useful tips ===== ===== Useful tips =====
-  * Before the input voltage is connected for the first time, the power supply output is disconnected even when the batteries are 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.
