Power Supplies

The power supply for an air purifier delivers electricity to the LCD, fan motor, heater, and, depending on the model, ionizer. Ensuring the power supply operates as designed requires using high-performance solid-state relays, vibration-resistant fuses, and multiple forms of overvoltage protection. Littelfuse supplies all these electronic components.
