●Advanced DSP digital control technology
The use of advanced fully digital DSP control technology makes the data processing more accurate and rapid, the output performance will be more excellent, and the reliability of the machine will be improved.
●Large LCD+LED display screen
Fully considered humanized design, perfect combination of LCD+LED, Chinese and English display, rich display content, easy to understand, and easy to operate. The LCD display panel is also equipped with a switch protection device to avoid various problems caused by collision or mispressing, making the user safer and more reliable during use.
●Highly guaranteed dual-channel AC power input function
Two sets of input from different power grids can be used for the main AC input power supply and bypass AC input power supply, so that the user's power supply is more comprehensively guaranteed.
●Frequency and phase sequence adaptive system
The output frequency can be set to 50Hz or 60Hz according to the mains frequency. The output phase sequence can automatically track and lock according to the input phase sequence.
●Intelligent charging system
Users can freely set the appropriate charging current (1~25A) on the LCD control panel according to the battery type, capacity and battery usage status. The scientific charging method has fully extended the service life of the battery.
●More excellent electrical performance
The efficiency of the whole machine is as high as 93%~94%, and the ECO mode is provided to increase the efficiency to more than 97%, which greatly reduces the power loss of UPS. It adopts full-bridge topology with output isolation transformer, which has stronger load capacity and impact resistance. The output load power factor reaches 0.8.
●Parallel function
Support 3 UPS parallel redundancy (option).
●Excellent battery management function
The TDF series UPS can automatically detect abnormal phenomena such as battery failure, insufficient power, and battery loss, which further improves the reliability and safety of the UPS.
