Three-Phase Pure Sine Wave High-Frequency Inverter (SF Series)
SF-10KW-3P / SF-15KW-3P / SF-20KW-3P / SF-25KW-3P — strong load capacity for three-phase motors, air conditioners, freezers, robotic equipment and more. 24V/48V DC input, three-phase AC output.
Product Features
- Strong load capacity and wide load adaptability — suitable for three-phase motors such as three-phase air conditioners, freezers and robotic equipment.
- Each of the three phases can carry load independently; the inverter can drive either three-phase or single-phase loads to meet different requirements.
- Ample protection modes give the unit outstanding performance.
- High/low voltage isolation design for safer operation.
- High-reliability design meets the requirements of use in vehicles and boats.
- Low no-load consumption and high efficiency — well suited for solar power systems.
- Small size, light weight and high power density; easy to operate.
- DC input 24V/48V; output is three-phase AC voltage.
