1. E300 mini universal inverter has compact structure and nice appearance. The appearance design has already applied for national patent (Patent No. is 200830155596.8 and 200830155597.2).
2. The optional keypad can be easily removed or installed according to user's requirements. With the indicator light on inverter, users can monitor the running status without keypad.
3. The mini universal inverter is used as supporting equipment for the textile industry, transmission machinery, etc. With the 1000Hz output frequency, it is also used in variable frequency control for grinding machines, engraving machines, centrifugal machines and so on.
1. Its power ranges from 0.25W to 3.7KW and its input voltage range is 220V±15% and 380V±15%.
2. The mini universal inverter has standard configuration including RS485 communication interface, Modbus protocol and built-in braking unit.
3. It can also achieve the functions of automatic voltage regulation and automatic current limit, to ensure the reliable operation.
4. Two kinds of installation method are available to meet your requirements and save more space.
5. The mini universal inverter can match with a controller keyboard that can be separately used with inverter.
