2. The advantages and disadvantages of modular UPS is the use of double-bus system wiring method?
3.UPS hot backup and machine and what is the difference?
4. What is the use of isolation transformers? In what occasion?
Answer yes yes ... thank you. Detailed point Oh
Frequency machine is directly used frequency frequency (50hz) the battery DC into AC power, and then transformer transformer 220 volts 50 Hz home AC. (The advantage is simple structure, a bit like a transformer power supply.)
High-frequency machine is the first of the battery through the high-frequency booster circuit boosted to high-frequency 220-volt pulse, the filter to 300 volts DC voltage, and then turn it into 220 volts 50 Hz home AC. (The advantage is that the output power can be automatically adjusted, energy-saving effect is good, a bit like switching power supply.
