1, high-quality pure sine wave inverter 2000W with charger and UPS features advanced digital control technology module, CPU intelligent management, LCD intelligent display frequency pure sine wave inverter --- interactive single-phase uninterruptible power supply - UPS input type: AC or DC or AC and DC output types: stable Uninterruptible AC voltage connections: battery, mains I. Features: 1, the output voltage constant frequency function: mains voltage instability, through this machine After the output voltage accurate and stable, such as in China, lack of electricity, when the mains voltage is 190V, 53Hz, then after this machine, the output voltage is 220V ± 3%, 50Hz ± 0.5; stable output voltage help to protect electrical equipment. 2, the inverter features: direct current DC into alternating current AC; battery combination and after, when the family, office, supermarkets, industrial areas and other power, can be composed of green silent generator; when outdoors without electricity area, namely can be composed of mobile power, user-friendly household electrical appliances at home; in the new energy industry, the inverter is an important integral part; 3, intelligent charging function: When the battery is not electrically connected to market power and the machine , the machine will automatically charge the battery, intelligent battery charging advantageous to protect and extend the service life of the battery; when the machine connected to the mains and battery consisting of UPS systems, system output electricity but also for automatic battery charging; charging divided into three sections charge: Section I: use maximum constant current fast charge to improve backup power as quickly as possible. Section II: Constant voltage gradually the battery is fully charged, the battery time to fully absorb the energy, protect the battery electrode to extend the life and avoid overcharging. Section III: when the sensed battery is full, it will switch to float voltage to maintain long battery at full charge status and automatically detect battery power, charging is completed automatically stop working to save electricity. Features built-in charger inverter is to solve the battery can not be charged in trouble, do not need to reprovision charger. 4, UPS function: battery and mains connected, form the output UPS systems, ensure that the load is not because of a sudden power cut and closed, to ensure that the load after power cut can continue to work; Step 1: When there is electricity mains after the regulator output directly and simultaneously charge the battery; Step 2: When the mains sudden power outage, in 5ms the system automatically switches to inverter power supply to ensure uninterrupted output; Step 3: When all of a sudden there are city After power-up, the system automatically converted to electricity supply, as well as the battery charge; Second, product characteristics: 1, pure sine wave output; 2, CPU management, intelligent control, modular composition; 3, LCD screen display, visual display various parameters; 4, multifunction machines, customers no longer need to purchase additional chargers, voltage regulators; 5, scalable backup time, external batteries, customers can complete the appropriate number of batteries according to their needs; 6, the series product anti-load capacity, strong load capability, in addition to drive all kinds of resistive load, but also various types of emotional load type equipment, such as motors, air conditioners, electric drills, fluorescent lamps, gas lamps and the like; can drive almost all of the load; 7, the frequency circuit design, system stability, low failure rate, long life, normal life can reach more than three years; 8, perfect protection function: low voltage, high voltage, high temperature, short circuit, overload protection; alarm reminder ; 9 by CE, EMC, LCD, RoHS, CCC certification; 10, the product warranty period of 2 years, free lifetime technical maintenance; Third, the product parameters: maximum continuous output power of 2000W maximum instantaneous output power of 4000W DC input voltage (battery) 24V or 48V (select) AC input voltage 220V ± 35% or 110V + 35% (selection) Frequency 50Hz ± 3% or 60Hz ± 3% (option) AC output voltage 220V ± 3% or 230V ± 3 or 240V ± 3% or 100V ± 3% or 110V ± 3% (selection) Frequency 50Hz ± 0.5 or 60Hz ± 0.5 (selection) battery charging current 0 ~ 15A Charge time is automatically detected and the number of batteries according to the battery capacity and charging protection, discharge protection, intelligent management Display Display LCD display 1 minute when the information input voltage, output voltage, output frequency, battery capacity, load status, status information output waveform Pure sine wave output, waveform distortion ≤3 overload capacity of 120% load automatically shut down when the 130% 10 sec when closing the conversion efficiency of 90% average conversion efficiency of conversion time when suddenly switch to the time when no mains inverter output of the inverter ≤5ms process, suddenly there is electricity input from the inverter into the mains time ≤ 5ms output overload protection, output short circuit protection, battery reverse polarity protection, input over voltage protection, input low-voltage protection, thermal protection Ambient temperature -10 ℃ ~ 60 ℃ Humidity 10% to 90% Altitude ≤4000m size 400 * Packing size 180 * 320 470 * 250 * 430 net weight (kg) 23 Gross Weight (kg) 25
