Pure Sine Wave Inverter  STI series
STI series is a sine wave power frequency inverter which can convert 12V or 24V DC to 220V AC 50Hz based on full digital and intelligent design. It features high reliability, high efficiency, concise outline, small volume, full protection functions, easy installation and operation. The inverter can be applied in many fields especially for solar photovoltaic power system.
 
Features:
 
1. Complete isolation-type inverter technology, noiseless output
2. Adoption of advanced SPWM technology, pure sine wave output
3. Dynamic current loop control technology to ensure inverter reliable operation
4. Wide DC input voltage range
5. Excellent EMC design
6. Low output harmonic distortion(THD3%)
7. LED indicators for input voltage range, load power range, normal output & failure state
8Optional energy saving mode
9. Extensive protections: reverse polarity, short-circuit, overload, under/over input voltage, over-temperature, and          inverter’s inner fault identification protections
10.Wide working temperature range (industrial level)
11.Continuous operation at full power
 
 
Electronic protection:
 
1. Output Short Circuit                        2.Input low voltage                 3.Input over voltage
4. Inverter abnormal protection             5.Overload                            6.Overheating protection
