High Frequency Online UPS

General Introduction
The high frequency online UPS is a new generation intelligent product, and it is especially designed for IT equipment, network communication equipment and other devices that have strict requirements for power supply. Considering the practical needs of some customers that ask for extremely high reliability, we also provide long backup time UPS aside from conventional type. Moreover, for models whose capacities are over 6KVA, active/standby failover configuration is available, thus greatly lowering failure rate as well as improving working reliability. In this way, some important equipment is provided with safe and reliable power supply.

Advantages
1. Double Conversion Technology
The online double conversion method is able to support the protected equipment with continuous green power supply, and this method refers to accepting AC input, rectifying to DC for passing through the rechargeable battery, then inverting back to AC output. Thus, the key electrical appliances will not be affected by power failure, instable voltage, frequency variation, harmonic distortion and other anomalies.

2. Sine Wave Output
For both battery mode and mains supply mode, this high frequency online UPS will offer sine wave output with low harmonic distortion, thus providing reliable power for connected loads.

3. Zero Transfer Time
Under the condition that mains supply fails or restores, there is no transfer time between battery mode and mains supply mode. Hence, the protected equipment will run continuously for some extra time.

4. Input Live Wire and Neutral Wire Detection
This function is available for models of 1~3K(S), and it is adopted to avoid reverse connection of live and neutral wires of mains supply.

5. Input Power Factor Correction
With the help of this function, the input power factor could reach up to over 0.95 at full load, thus ensuring excellent power quality.

6. DC Start
If our high frequency online UPS is needed to start up computers or other loads when mains supply fails, the storage battery could be directly used to realize DC start, making our product more reliable and convenient.

7. Bypass Protection
The bypass circuitry enhances our product's ability to deal with emergencies, and if the connected load has some special requirements for power supply, such as the input voltage shouldn't be too high, bypass overvoltage protection will be carried out to make the load get rid of the danger of overvoltage.

8. Auto Start
When mains supply is under abnormal state, our product will be switched to battery mode in order to provide power until it shuts down automatically as a result of the battery's low voltage. Then, when mains supply recovers, our product will be turned on automatically to supply power, avoiding the need of manual start up.

9. Long Backup Time Model
Aside from standard types, we could also provide customers with long backup time type online UPS. If appropriate battery is applied, 8 hours of backup power would be offered, which is long enough to meet practical applications. On the other hand, the long backup time type also has improved recharging property, and the initial charge current is about 5A~10A.

10. Compatible with Generator
Due to the wide voltage and frequency input ranges, our product is compatible with major generators on the market. It has a longer life span, and it can purify the power electricity produced by generators, thus supplying clean, safe and stable power for connected equipment.

Applications
Owing to the advantages demonstrated above, our high frequency online UPS is commonly accepted in different fields, such as server, bank, security system, medical system, voice over IP, laboratory equipment, precise instrument, network communication equipment, manufacturing and control systems, etc.
