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 is 110-300Vac, 172-268Vac±7Vac under full load. The frequency of using the battery is reduced, thereby prolonging 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 208/220/230/240Vac, 50/60Hz power grid system. The efficiency of the whole machine ≥90%;
4、Strong load adaptability and output overload and short circuit capability, 1-3KVA: 125% load for 60s, 150% load for 300ms, alarm and bypass;
5、It can be equipped with various types of generators to reduce the customer's operating costs;
6、The extremely low ripple charger under intelligent control extends the service life of the battery. The intelligent control of the charger is professional for lithium batteries (such as lithium iron phosphate or ternary lithium batteries);
7、The fan is controlled intelligently, the wind speed can be adjusted reasonably according to the load, and it has the function of fan failure alarm protection and display code;
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;
9、It adopts 19"inch rack structure design, which can be matched with standard communication cabinet, which greatly saves the space of data room. Safe, stable and easy to maintain
10、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;
11、Adopting extremely sensitive current peak protection circuit design, so that the UPS has excellent protection performance under the conditions of non-linear load, cold load impact, output short circuit, etc.;
12、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: SNMP network communication card, RS485, dry contact, USB interface, etc.
