KELONG UPS power KR33 (three three) product introduction:
KELONG KELONG stock three high frequency KR33 series UPS is designed for data center network, high performance sine wave computer room design uninterruptible power supply, the power supply provides high reliability for the protection of important financial, communications, transportation, insurance, securities, taxation, military, energy, education, government, manufacturing and companies and other industries.
KELONG KELONG three three high frequency KR series is double conversion on-line real UPS, using advanced power control technology and superior performance of SPWM inverter, distortion with high input power factor and low input current harmonics, is a new generation of green power supply device.
Energy saving and high efficiency
Using the advanced PFC control technology, the input power factor greater than 0.98, greatly increase the energy utilization rate, reduce network load, saving distribution costs; the small size and light weight, low calorific value, improve the utilization rate, reduce the cost of investment environment.
Digital DSP control
UPS inverter control, phase synchronization, input PFC control, logic control, and so the use of DSP digital control, high precision, fast speed, good overall performance.
Intelligent fan speed control
Fan speed with load capacity can be automatic speed when the load is small, the automatic fan speed slow, when the load speed large wind turbine automatic speed control design; intelligent greatly extend the service life of the blower, reduce the working noise of the whole machine.
Manual maintenance bypass design
The design of manual maintenance bypass channel, to ensure that the machine in the maintenance of the load can be uninterrupted power supply, greatly improve the reliability and maintainability of the system operation.
Reliable electromagnetic compatibility
By the authority and professional EMC test, including conduction interference, radiation interference, conduction immunity, radiation immunity, power drop, group pulse, electrostatic discharge, surge and other special content, can not only eliminate the various characteristics of power grid disturbance excellent electromagnetic compatibility, and can effectively reduce and eliminate the interference of professional application UPS the radio communication, suitable for high frequency ultrasonic system.
Multi-level protection function to ensure the safe operation of the system
The utility model has the functions of input overvoltage, input undervoltage, overload, short circuit, phase error, phase sequence, etc. the utility model has the advantages of enhancing the adaptability of the UPS to the electricity market and the ability of resisting the load impact.
Independent master-slave parallel technology of independent patent
With a strong parallel capability, no need to set the number of machines, can be arbitrarily parallel line expansion or N+1 redundancy parallel, doubling the output power.
The UPS parallel units are independent and need not be matched strictly to ensure the simplicity of parallel engineering.
Edge construction investment, with higher adaptability, availability, scalability and lower maintenance costs.
Adaptive control technology to ensure that the UPS parallel unit installation, maintenance is simple, safe and reliable operation.
Chinese / English LCD LCD display
In English / LCD display design, simple operation, convenient maintenance and daily management, real-time display the operating parameters and operating status of UPS; CPU in the machine can record historical events and alarm information, the information storage capacity of up to 1000, including: power outage calls time, depth of discharge (more than 50%) the number of bypass time record, alarm records, negative change records, historical records of protection action.
Humanized panel function design
Can set the output frequency: can be set through the panel output frequency of the machine, flexible to adapt to different requirements of the grid.
The output voltage can be set: the output voltage value of the machine can be set through the panel (220V/230V/240V), flexible to adapt to different requirements of the grid.
Set the input frequency synchronization range, synchronization speed and over range alarm points.
Can set the abnormal input (high / low).
Perfect network monitoring program
Support RS232 data communication interface, SNMP network adapter, through the power monitoring software, UPS operation and maintenance of the remote, remote and network monitoring and management, simplify network management, improve the reliability of the system.
The single remote monitoring management of UPS through RS232 interface and computer serial port to connect the computer to establish communication links with UPS, real-time monitoring of the operation state of UPS, implementation of UPS self diagnostic procedures, regularly send inquiry instruction, power supply is abnormal, the pop-up interface or terminate the program operation, automatic archiving, and timely report the relevant information.
The designated multi computer monitoring and management network in a server or workstation (called local machine), through the RS232 serial port and UPS communication line, on a network server or workstation (remote machine) and local communications, local and remote machines are running UPS power management software, the alarm control management a shutdown function one or more remote machine local machine.
UPS network management to support SNMP network management protocol, through the SNMP network adapter, UPS system as a separate node access network, network management functions can be achieved. Users can access the remote UPS (Web) through the browser, but also through the network platform for remote monitoring and management of UPS (SNMP function).
