E300 Mini Universal Inverter, High Speed Inverter, Energy Saving Unit, Plastic Machine Inverter

Product Description
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.

Features
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.

	Acc /Dec time setting		0.1~600s continuous setting; Acc /Dec S curve and linear mode for choice
	DC braking		Action frequency: 0~500.0 Hz; Action time: 0~20.0s
	Low noise running		Carrier wave frequency range is1.5 KHz ~ 12.0 KHz that is continuously adjustable, so as to minimize the motor noise.
	Operating function		Upper and Lower frequency setting, reversal operation limitation, RS485 communication, frequency increasing/decreasing control mode, etc.
Display	Operation panel display	Running state	Output frequency, output current and voltage, motor speed, frequency setting, module temperature, analog I/O and so on.
		Alarming	The operation panel shows the recent four times failure record, and the last running parameter record of output frequency, output current, output voltage and DC voltage during last fault trip period.
Protection / alarming function			Overcurrent, overvoltage, undervoltage, overheating, short circuit, etc

Note: Only some derivatives of the E300 have the function of RS485 communication (1) listed in the table above.
