Renda UPS power supply power frequency three in three out 10-120KVA application field:
Renda power frequency three-in, three-out 10-120KVA uninterruptible UPS power supply inherits the excellent quality of Renda products, and has humanized management functions, which can provide high-reliability power protection for users' enterprise-level servers, small and medium-sized LANs, small computer rooms and other precision electronic instruments.
● Touch screen
Powerful Chinese/English display interface: using full digital touch screen large screen LCD Chinese and English display, the display content can be selected and set in Chinese/English, and the operating status, operating procedures, data collection, troubleshooting data and other contents are clear at a glance;
● Advanced working mode
Double conversion online design, so that the output of UPS is a pure sine wave power supply with frequency tracking, phase-locked voltage regulation, noise filtering, and no interference from grid fluctuations, providing more comprehensive protection for the load.
Output zero conversion time, to meet the high standard requirements of precision equipment for power supply.
Adopt six-pulse rectification to improve the utilization rate of electric energy, greatly eliminate the harmonic pollution of UPS to the mains power grid, and reduce the operating cost of UPS.
● Economic Operating Mode (ECO) function
When the input mains power is within a fixed range, the energy is directly supplied to the load by the input mains power, and the inverter is in a waiting state; When the input mains power is abnormal, it is immediately converted to inverter power supply. ECO operation mode can be efficient and energy-saving and reduce user costs.
●Optimize the functional design of the battery pack
Through innovative optimization of battery pack function design, whether it is a standard model or a long-delay model, it saves battery consumption more than traditional design solutions under the condition of meeting the same backup time.
●Strong environmental adaptability
Wide voltage range, avoid frequent switching to battery power supply when the grid voltage changes greatly, and adapt to areas with harsh power environment.
Wide input frequency range to ensure that all kinds of fuel generators can work stably and meet the requirements of users for the use of oil turbines.
● Reliable protection function
With the function of booting self-diagnosis, it can find the hidden fault of UPS in time and prevent problems before they occur.
With input over-under-voltage protection, output over-current, overload, short-circuit protection, PFC and inverter overheating protection, battery overcharge and under-voltage warning protection and other protections to ensure the stability and reliability of system operation.
With automatic bypass function, when the output is overloaded or faulty, it can be continuously transferred to the bypass working state by the mains to continue to supply power to the load.
With DC start function, UPS can be directly started in the state of no mains power to meet the emergency needs of users.
●Rich options, intelligent management
Chinese LCD interface can display load, battery capacity, input and output parameters and fault information, which is convenient for user operation and maintenance management.
· RS232 local monitoring. UPS is equipped with RS232 interface as standard, and local monitoring can be easily carried out through the included monitoring software.
Optocoupler dry contact. Through the DB9 dry contact interface, the main abnormal information of the UPS can be led out through the dry contact, and the dry contact signal is isolated by optocoupler, and the user can easily use these signals to control some strong and weak current equipment.
· SNMP card/centralized monitoring card (optional). Through the optional SNMP card, the UPS can be connected to Ethernet for remote monitoring. The centralized monitoring card can realize simultaneous monitoring of multiple machines and record the events and alarms of each machine. SNMP card/centralized monitoring card is a goldfinger board structure, users can invest in installments and purchase when needed.
Alarm relay card (optional). Up to 6 alarm relay outputs provide a high-capacity interface for easy connection of extended alarm devices.
Parallel interface module (optional). Through the optional parallel interface module, 4 machines can be powered in parallel.
● Fault isolation
The maintenance bypass module can be separated, and the maintenance bypass module can be taken out online when UPS fault needs to be repaired, while the output load is maintained without interruption.
