PDU: Power Distribution Unit and UPS: Uninterruptible Power Supply developed by PAVOTEK for Turkish Armed Forces (TAF) and to be used in AY Class Submarines. The main purpose of PDU is to activate connected devices in a certain order. The software on it determines the operation of the device for a period of about 90 seconds and in what order to power the connected units. Lithium – Ion battery is use in UPS. Normally, power from an external power source is transferred to the output. If an interruption is detected here, the battery is activated. This transition is carried out in such a way that it cannot be detected from outside and does not cause disruption.
