Rack type online UPS power system-Keda UPS-Guangdong China UPS & voltage stabilizer

Description

KDH Series rack online UPS power supply is a high-performance UPS designed for the user s’ integration overall engine room, small size, the structure suitable for 19 # rack cabinet installation, pure on-line design, zero interruption conversion, sine wave output, can fully resolve all power failure issues, such as mains power interruption, sustained high-voltage, voltage drop, surge distortion, clutter interference, frequency fluctuations, can be stable and reliable protection of the safe operation of the user equipment.

Applications：
Widely used in network-centric computer room, communications equipment control center, automation equipment overall cabinet, rail traffic signal control equipment, etc.

Technical merits
●Sine wave output
Whether in mains power mode or battery mode, the output will be low-distortion sine wave power, can provide the best power protection for the user's equipment.
●Zero conversion time
When the mains power failure or restart, UPS conversion between mains power mode and battery mode is effective as zero to ensure that the reliability of the load operation and data retention.
● Strongly engaged in interference
For electromagnetic and radio frequency interference, in accordance with international standards EN50091-2 and IEC61000-4 series of standards for the design of the UPS to effectively improve the use safety and reliability.
● Input power factor to amend
With input power factor correction, in the fully loaded case, input power factor can reach more than 0.95, which can be accessed by inductive load, and users’ grid environment will not be contaminated.
● Input live line and null line detection function

Have input live line and null line reverse connection detection function to avoid the UPS mains power input live line and null line reverse connection.
●DC power start
When the city electricity power failure, if the need to start the computer or other loading equipment, UPS can DC power start through battery, it is more convenient and reliable to use
● Automatic restart function
When the city power abnormal, the power use up at battery mode, will automatically shut down when the city power returned to normal UPS will automatically start and resume normal power supply, user don’t need to turn on the UPS one by one.

● Long-term UPS powerful charging function
Long-term models extend the discharge time, also have a strong ability to charge the battery, can provide approximately 4-9A of the initial charge current.

●Self-examination functions
Can simulate the situation of power interruption, into the battery-powered mode, This feature can carry out by self-test button on the panel at any time, also can use with electronic monitoring software to carry out at regular or irregular time.

●Can be used with generator

Input voltage and frequency range, can be used with generator, the using time will be longer,

can effectively isolate the negative power generated by the generators to provide clean, safe and stable power supply for the load
