1. All power sources (JI) and Voltage converters (PN) are designed for uninterrupted supply power supply of FLOUTEC-TM measuring complexes and other systems and means of automation manufactured by "DP UkrGasTech" LTD.
   When the AC mains is turned off or the mains voltage drops below the norm, JI and PN provide a shock-free circuit switching power to operate devices from a backup battery.
2. JI and PN have an output voltage backup circuit, a circuit for monitoring and diagnosing the state of the supply network and voltage battery power supply, an automatic protection circuit against short circuits in the battery and load circuits, as well as providing automatic recharge of the backup battery.
3. JI and PN are designed to work with non-maintenance batteries (batteries) with a rated voltage of 12 V (25.2 V), nominal capacity of the battery - from 12 to 33 Ah.
   The battery charge is provided in a "floating" mode (float charge).
4. JI and PN are intended for operation outside explosive zones in rooms at an ambient temperature of minus 40 to plus 70 °С.
