AT series

Stable PWM method

The 3STEP charging method, which is one of the existing inverter driving methods, can charge the battery stably during DC output after inputting the AC voltage, so that the system can be implemented stably even if it is applied to any system such as industrial, solar power generation, camping, dew point.

Heat dissipation function

Unlike other companies' products, ATC has increased the content of heat sink and reinforced internal heat sink. By attaching the heat-dissipating fan to the secondary, the life of the parts due to heat is shortened and the inconvenience to use is minimized.

Indicator function

We check the operation status on the product and check it on the display window so that the connection status and product status can be recognized. Charging progress and battery voltage are displayed to maximize user convenience such as actual battery voltage.


Product Features

※ It is a breakthrough product that program control each operating point by microcomputer circuit configuration

※ Because of the improvement of the quality, the normal output

※ When the input voltage fluctuates, stable output power is supplied by converting output static pressure within 5%

※ Minimize the damage of the battery electrode plate to increase the efficiency and charging method

※ I / O protection circuit automatically protects circuit protection Built-in automatic stop program

※ Designed to operate normally in low temperature and high temperature in external environment
