Voltage spikes, fluctuations and power outages can happen anywhere in the world, from large urban centers to remote regions where the mains grid is unstable and power supply is unreliable. Conventional vaccine refrigerators can be damaged by electrical problems, exposing vaccines to rising temperatures for unknown periods of time before the damage is noticed. That’s why every MetaFridge mains-powered refrigerator includes PowerMinder technology, a built-in system that guards against damage from dangerous voltages and maintains safe storage for sensitive vaccines.
PowerMinder performs two essential functions. It stabilizes voltage fluctuations within a wide input range, and it provides protection from high or low voltage events outside the safe and acceptable range. The PowerMinder voltage protection and stabilizer is integrated into every MetaFridge, so each unit can be plugged directly into the wall socket without need for external protection.
