Product Detail

SKGH11-1KVA-15KVA

System Overview
This product is an uninterruptible power supply product with single-phase input/single-phase output, three-phase input/single-phase output, medium and small power, pure online UPS with full digital control technology, and N+1 parallel redundancy function. It adopts double conversion system, output isolation transformer design, advanced SMT technology, and has outstanding high stability and high reliability. The output isolation transformer effectively suppresses and isolates the surge, spike interference and load impact of the mains, and can greatly improve the harmonic distortion of the load current, so that the load and the UPS are in a better state of coordination.
Use load category
The design and application environment of this series of products is small and medium-sized key equipment systems, such as small and medium-sized financial network equipment, small data processing centers, key medical equipment, manufacturing process control systems, and telecommunications equipment industries. Such as: data centers, communication rooms, network management centers, financial centers, securities trading, settlement centers, bank data centers, stadiums, traffic control centers, tunnel lighting and monitoring centers for highways and railways, information centers for ports and docks, semiconductors Production line, enterprise automated production line and its control system.

High performance index

1. Thyristor rectifier and IGBT inverter technology under full digital control; online single-in-single-out, three-in-single-out double conversion structure, with slow start function, which improves product reliability;

2. Use output isolation transformer technology to support 200, 220, 230, 240Vac, 50/60Hz power grid system;

3. Wide input voltage and frequency range, single-phase 160-280Vac, three-phase 286-475Vac, 50/60Hz±5%, strong grid adaptability;

4. Powerful load adaptability and output overload and short-circuit protection capabilities. Buffer technology and peak current protection technology are used to prevent load impact from switching to bypass under 0-100% sudden changes; output voltage and frequency are optional;

5. The efficiency of the whole machine can reach more than 85%. In ECO operation mode, its energy conversion efficiency is as high as 98%, and the energy saving effect is very significant;

6. It can realize the parallel operation of multiple power supplies without master-slave redundancy, and the parallel circulating current is ≤5%;

7. Intelligent charging design, with three constant charging, floating charging, and equalizing charging methods, alarming and protecting the battery when it is too low or high, and real-time diagnosis of battery status and feedback data;

8. The color dot matrix 2.8-inch LCD screen + LED is used in combination with the keyboard to comprehensively and intuitively reflect the operating status, parameters, various information and temperature control of the UPS system, and the operation is convenient.

9. The battery detection mode can be set on the display panel to calculate the battery discharge time; the UPS operating mode (inverter priority or ECO energy saving mode) can be set; intelligent fault diagnosis can be performed, historical information and fault information can be inquired through the fault Record, judge and analyze the cause of failure; understand UPS operating time and accumulated operating data and other functions;

10. It can realize remote monitoring of LAN or WAN through SNMP network adapter, equipped with RS232 and USB interface, equipped with EPO remote emergency shutdown interface, optional RS485 and multiple dry contacts;

11. The design of the air duct for air outlet after moving forward is conducive to the product installation environment and reduces the failure rate of the product;

12. The self-locking universal roller design is easy to move and ensure fixed;

13. Small size, strong function and easy maintenance among similar products.


Safe, stable and easy to maintain

1. Using MCU (microprocessor) to implement full digital control of each power conversion link of UPS, the consistency and stability of the system are higher;

2. The use of controllable rectifier design greatly improves the adaptability to the city power, and is safer and more reliable for the inverter;

3. Built-in output isolation transformer can reduce the influence of zero-ground voltage and load harmonic current on the inverter;

4. The independent battery interface avoids serious failures caused by installation errors and greatly reduces the risks caused by operation;

5. More than 90% of the components in the system design adopt international brands, and the equipment has undergone 24-hour aging and related verification tests before leaving the factory to ensure the high reliability of the system.


Rich options

A variety of options can be connected: redundant parallel card and communication cable, SNMP network adapter, RS485 and dry contact, expandable charging current, etc.


1. Using MCU full digital control, higher system consistency and stability;

2. Wide input voltage and frequency range, super power grid adaptability;

3. All-digital non-master-slave, autonomous redundant parallel current sharing control technology;

4. Advanced battery intelligent management, battery test and inspection design; high-current charging and protection functions to ensure the long service life of the battery;

5. Powerful output short circuit and overload capacity to ensure the stability of the system and the safety of the system under extreme conditions;

6. The large dot-matrix color LCD screen displays the operating status of the power supply, with a friendly interface, which is convenient for customers to use and operate;

7. Double-conversion online technology, output isolation transformer, completely isolate the influence of mains and diesel engine on the load.

8. The volume of the single machine is the smallest. All products are equipped with universal brake wheels for easy movement.
