Uninterruptible power supply container unit UPS CU



Uninterruptible power supply UPS is designed to provide uninterruptible power supply to the auxiliary systems and automation systems at oil and petroleum products pumping stations. UPS ensures the quality of power supply of connected to them consumers in accordance with the requirements of GOST R 54149 for mains operation, diesel generator units and in stand-alone mode for accumulator batteries operation.


- Galvanic insulation;

- Low distortion of input current;

- Cyclic charging and temperature compensation of accumulator batteries charge;

- Function of the battery test for accumulator the batteries;

- Modular UPS design;

- Protection against back current;

- Redundant system for UPS «N+2» module;

- Automatic and manual bypass;

- Remote monitoring

- Analysis of quality factors of electric energy of input power system;

- Local and remote control of parameters for input electric power system;

- Record of oscillograms of input power system in case of incident;

- Registration of control data of input power system for 2 years;

- Protection against surge overvoltage.


UPSU provides electricity to connected electric users with the necessary indexes for reliability and quality of electricity under the following violations in the electricity system:

– loss of voltage;

– voltage falls;

– voltage surges;

– undervoltage;

– voltage boost;

– electromagnetic and radio frequency interference;

– frequency deviation;

– Switching transients; harmonic distortion.

– UPSU provides remote observation (monitoring) of the state of their equipment, the quality indicators of input and output voltage and other relevant parameters of the current state of UPSU, fault monitoring, filing of UPSU operation;

– UPSU provides noise elimination from the rectifier and inverter equipment coming into the main electrical grid.

Application area

It is used in the oil and gas stations.
