Product description:

Our Online Double Conversion UPS is a high-reliability power protection solution designed for small and medium-sized enterprises, web servers, and small servers. The UPS features an advanced double conversion topology to ensure clean and stable power under any circumstances.

When the utility power is normal, the UPS converts AC power to DC through the rectifier and then back to AC through the inverter to power the equipment, while trickle charging the battery to maintain its health. This design not only eliminates voltage fluctuations, frequency drift, and noise in the utility power but also enables a 0-second switch to battery power when the utility power is abnormal, ensuring continuous operation of the equipment, no data loss, and no equipment damage.

When the utility power is abnormal, such as during a power outage, over-voltage, or under-voltage, the UPS immediately switches to battery power mode, and the inverter continues to provide stable AC power to the equipment, ensuring uninterrupted operation of critical equipment. This seamless switching capability is crucial for protecting equipment with high power quality requirements.

The online interactive UPS is a UPS designed for small and medium-sized enterprises, website servers, and small servers. This product adopts a special topological design. When the main power supply is working normally, the UPS transfers power to the connected devices and keeps the output voltage stable by adjusting the transformer of the input voltage; when the main power supply is abnormal, the UPS immediately switches to battery power supply, thereby protecting the equipment from power fluctuations or power outages, ensuring that the data is normal and the equipment is not damaged.


KHZ-H11-3KVA


Application Areas:

●   Business/Bank: Office equipment for education, business, banks, etc.

●   Computer rooms for small and medium-sized enterprises: Network computer room servers, precision instruments and equipment

●   Monitoring and automation systems: Monitoring systems, electric power railway signal systems, etc.

●   Offices: Printers, fax machines, access control and attendance equipment, etc.

●   Large enterprise branches: Companies, enterprises, etc.

●   Homes: Desktop computers, home theaters, home appliances, etc.

●   Supermarkets: Cash registers at counters, monitoring equipment, etc.


Product Features:

●   Complete Isolation of Utility Interference:

Using advanced double conversion technology, the utility AC input is converted to DC and then back to AC, effectively suppressing various utility interferences such as surges, spikes, line noise, undervoltage, overvoltage, lightning, frequency changes, etc., providing pure and stable power for equipment.

●   Zero Transfer Time:

In the event of a utility input power failure, it can instantly switch from normal mode to energy storage mode, with no interruption in the output power, ensuring continuous operation of equipment.

●   High Power Quality:

The output voltage and frequency are stable, independent of the utility input voltage and frequency, and the output waveform is a pure sine wave, meeting the requirements of equipment with extremely high power quality demands.

●   Extended Battery Life:

The battery has a relatively low discharge probability, only discharging when the AC input voltage exceeds the specified range or fails, thus extending the battery life.

●   High Reliability:

The rectifier and bypass input are connected by two independent input terminals, enhancing the fault tolerance of the UPS. The rectifier and inverter use advanced control schemes, enhancing the system's anti-interference capability and reliability.

●   High Efficiency:

Using high-frequency rectification technology, it has a high input power factor and low input harmonic current, improving energy utilization efficiency and reducing operating costs.

●   Robust Materials:

Using three-proof coating technology to protect PCBA, it has superior insulation, moisture-proof, leak-proof, shock-proof, dust-proof, corrosion-proof, aging-proof, mildew-proof, component loose-proof and insulation corona resistance properties, extending the storage time and service life of PCBA.

●   Rigorous Production Process:

From SMT, insertion, assembly to production line testing, aging tests, quality inspection tests, packaging and other processes, all are strictly quality controlled to ensure the high quality and reliability of the products.
