The Power supply back-up provides backup power to refrigerators, thermostatic cabinets, refrigerated incubators and freezers in the event of power outages and protects against disturbances in the power grid.

The system allows the equipment to operate safely until a stable power supply is restored or until the battery is completely discharged. In the case of drug and vaccine storage, the battery backup of the pharmaceutical refrigerators allows the so-called "cold chain" to be maintained, even in the event of a power outage of 4 to 30 hours.
