ST1-3K UPS Appearances of Both LED and LCD
The left side is UPS with LED front panel, and the right side is UPS with LCD front panel.

The advanced DSP digital control technology makes the UPS have more stable performance and more reliable quality.

1. Advanced DSP digital control technology
The advanced DSP digital control technology makes the UPS have more stable performance and more reliable quality.

2. Environmental protection
Our products are environment-friendly. They perfectly meet the requirements of Chinese National Pollution Control Management of Electronic Products. The products will not cause any harms to environment and human beings in normal usage.

3. Active input power factor correction (PFC)
The active input power factor correction under digital control keeps the input power factor above as high as 0.99. This can effectively prevent the electric grid environment from pollution. Hence, it saves power and reduces system cost.

4. Wide range of input voltage and frequency
The extremely wide range of input voltage and frequency can keep stable in utility mode, even in a place where the electric power environment is bad. It reduces the times of battery charging and extends its service life.

Input voltage range: (1155-3005)Vac
Input frequency range: 40-60Hz/50~70Hz(adjustable)

5. Zero transfer time
When utility power supply is abnormal, UPS immediately turns to battery supply. The transfer time is zero. So it effectively guarantees the safety and reliability of load operation.

6. Frequency adaptive system
It can be set up as a fixed 50HZ or 60HZ system, or it automatically identifies and adapts the 50HZ/60HZ power supply system in accordance with the requirements of different power supply systems.

7. Strong expansibility function
The intelligent slot provides abundant expansibility. There are USB cards, AS400 cards, CMC monitoring cards, SNMP cards, RS485 cards and EMD environment monitoring cards for your consideration.

8. The load power factor is 0.8
It adapts the features of most current electric equipment and elevates the load-bearing capacity of the machines.

9. Used with generators
The wide range of input voltage and frequency can effectively separate the harmful power produced by the generators, and provide pure, safe and reliable power source.

The ST series uninterruptible power supply employs new DSP digital control technology. It is more reliable in performance.

Note: (Power of generator 2 times of UPS rated power)
