成果简介	NOVELTY - The device has a protection unit, a charger (2), a direct current power supply unit (7), a storage battery (1), a storage battery thermostat (3), including a thermostatic case, and an automatic switch (5) connecting the storage battery circuit to the load (9) and connected to each other. The storage battery is placed in a thermostatic case with heating plates, and is equipped with a temperature sensor and a control unit. The power supply unit is connected to the storage battery thermostat. The charger is connected to the storage battery. The charger is made adjusted to a nominal voltage equal to the charging voltage of the storage battery, and an output current limitation that does not exceed the maximum charging current of the storage battery. USE - Uninterruptible power supply device for low-current equipment with direct current designed with possibility of connecting to alternating current network of city lighting used in electrical engineering field. ADVANTAGE - The device ensures reliable autonomous uninterruptible power supply of low-current equipment with direct current from the city lighting network for a long time in a wide temperature range. The charger is designed to have a nominal voltage equal to the charging voltage of the battery and an output current limitation that does not exceed the maximum charging current of the battery. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the uninterruptible power supply device for low-current equipment with direct current designed with possibility of connecting to alternating current network of city lighting.
