Improve, the service life of indirect ATM Switching Power Supplies is also improved.
MCU 5 pin are that the 1KHZ write trembles frequency signal output, and its signal output is sent to PFC work frequency after integration
Rate shakes pin, and the purpose so designed is the interference to power network when can largely reduce PFC work, is also just improved
EMC indexs, make more green ATM Switching Power Supplies.
MCU 13 pin JDQ are the signal output that upper electric control inputs soft-start circuit, and MCU 8 pin P-OFF are upper automatically controlled
The signal output of pfc circuit work processed, MCU 7 pin are the signal output that upper electric control pwm circuit works, MCU 10 pin TX again
The signal output of delay output circuit work is exchanged for upper electric control, four signals of the above control for each functional module electrifying timing sequence
Signal output, the purpose so designed be in order to substantially reduce dash current during the upper electricity of start, thus avoid ATM system and
Sizable input dash current that ATM Switching Power Supplies powered on moment is produced, it is therefore prevented that because start powered on moment input impact
Electric current is excessive and makes the risk of city's electric tripping.
MCU 9 pin export for various abnormality alarm signals.This signal is connected to ATM system background monitoring, once
Generation is abnormal, and all thus signal sends alarm.
In summary, the uninterrupted ATM of this high energy efficiency powers high frequency switch power, employs energy-saving design, efficiency reaches
More than 90%, product cost is reduced, power-efficient and Module Reliability is improved, it is to avoid alternating current power failure or power failure, visitor
The economic loss at family can not be guaranteed, and the shortcoming of inconvenience is brought to client, can alleviate what electrical equipment was brought to power network
Immense pressure.This ATM power supply belongs to green power supply, is the higher ideal source of site requirements of powering.
