Multiple Universal Travel Charger 4 USB Ports

Multiple Universal Travel Charger 4 USB Ports 

• High-frequency machine based on microprocessor (CPU) chips as a processing control center, is a complex hardware simulation circuit burn in microprocessor, in the form of a software program to control the operation of UPS. As a result, has smaller volume and weight is greatly reduced, the manufacturing cost is low, the price is relatively low. The high frequency machine generally in more than 20 KHZ inverter frequency. But the high frequency machine under the condition of bad power grid and environmental tolerance ability is poor, is applicable to the power grid is stable and less dust, temperature/humidity appropriate environment.
  

• High frequency machine and power frequency comparison: small size, light weight, high efficiency, low operating costs), low noise, suitable for office space, cost-effective (under the same power, the price is low), the space, small environmental impact, relatively high frequency charger for copiers, laser printers, and motor caused by the impact (SPIKE) and TRANSIENT response (TRANSIENT) vulnerable, due to the mains and load machine power frequency transformer isolation, the mains harsh environment, power frequency machine than high frequency function to provide a more secure and reliable protection, in some occasions, such as medical, require charger have isolation device, therefore, For industrial, medical, transportation and other applications, the power frequency machine is a better choice. The choice of the two should be considered according to the customer's different, installation environment, load conditions and other conditions.
