High performance index

1. Adopt advanced high frequency switching power supply rectification and PFC (power factor correction) technology, input power factor ≥ 0.99, input harmonic truth degree THDI ≤ 3.5%, is an energy-saving and environmentally friendly green power supply;

2. Wide input voltage range, 160-300Vac under the input single-phase full load condition (the load can reach 115Vac or even lower under 50% load); under the three-phase input full load condition 304~478Vac. The frequency of using the battery is greatly reduced, thereby extending the service life of the battery.

3. Using a new generation of IGBT inverter control technology, the output voltage and current performance is more excellent. Online single-input single-output double conversion structure, supporting 220/230/240Vac, 50/60Hz power grid system.

4. The efficiency of the whole machine is ≥90%, and the efficiency of the whole machine can reach more than 98% in the ECO state;

5. Super load adaptability and output overload and short circuit capacity, 1-3KVA: 120% load 60 seconds, 150% load alarm immediately transfer to bypass; 6-10KVA: 105% ~ 130% load 10 minutes, 130% load 1 second;

6. It can be equipped with various types of generators to reduce customers' operating costs;

7. The temperature compensation and extremely low ripple charger under intelligent control extend the service life of the battery.

8. The use of dot-matrix LCD screen + LED combined with the keyboard can comprehensively and intuitively reflect the operating status, parameters and various information of the UPS system, and the operation is convenient. Intelligent fault diagnosis can judge and analyze the cause of the fault through the fault record;


Safe, stable and easy to maintain

1. Adopt a new generation of DSP digital signal processor technology to improve overall response speed, reduce distortion, and make the system more consistent and stable;

2. Adopting extremely sensitive current peak protection circuit design, so that the UPS has a good protection performance under the conditions of non-linear load, cold load impact, output short circuit, etc.;

3. More than 90% of the components in the system design adopt international brands, and the equipment has undergone 4 hours of 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 cable, SNMP network communication card, RS485, dry contact, USB interface, etc.
