LIRUISI High Frequency Tower Ups Uninterruptible Power Supply 3E20KS
Product introduction:
The high-frequency 3E20KS UPS power supply has a wide input voltage and frequency range, which can effectively isolate the bad power generated by the generator and provide pure, safe and stable power for the load.
way of working:
Three-in single-out, double-conversion online work Three-in single-out operation.
When choosing a high-frequency tower-type uninterruptible power
supply (UPS) with capacity of 3E20KS, the following factors need to
be considered:
Load type: Choose an appropriate UPS according to the actual load
type, such as computer equipment, communication equipment, network
equipment, etc.
Output waveform: Choose the output waveform of pure sine wave or
nearly pure sine wave according to the actual demand to ensure the
stability and reliability of the equipment.
