Humidity: Less than 95%RH, without condensation.
Vibration: Less than 5.9m/s²（0.6g）. Storage temperature: - 20℃～+ 60℃.
High performance: Vector V/F control technology to achieve a three-phase AC induction motor control.
SD90 series general type of frequency inverter is based on EH600A, it is based on vector quantization V/F control technology, covering EH600A series all software functions, and use the latest generation of Infineon IGBT module. Product appearance, internal hardware and structure design are more reasonable, so that the machine reliability is higher. SD90 series inverter are widely used in textile, metal, plastic, wood, chemical, ceramics and other ancillary equipment; Heating, water supply, central air conditioning, air compressor and other energy-saving projects.
Non stop Function: Load feedback energy compensates the voltage reduction so that the AC drive can continue to run in a short time in case of power interruption.
Rapid current limiting: Rapid software and hardware current limiting technology helps to avoid frequent over-current fault.
Timing Control: Timing control function: Set the time range: 0.0Min ～ 6500.0Min
Bus Support: Comply with international Modbus communication
Command source: Operation panel reference, control terminal reference, serial communication port reference. These can switch through various ways
Frequency source: Seven frequency sources: digital setting, analog voltage setting, analog current setting, pulse setting, serial port settings. These can switch through various ways
Auxiliary frequency source: Seven auxiliary frequency sources, which can flexible achieve auxiliary frequency fine-tuning and synthesis frequency
Input terminal: Five digital input terminals S1～S5,1 analog input terminals Ai1, which supports 0~10V or 0～20mA current input,1 high-speed pulse input terminal HDI, which can receive the highest 50KHz frequency pulse input.
Output terminal: One digital output terminal, 1 relay output terminal, 1 analog output terminal A0, support 0 ~ 20mA current output or 0 ~ 10V voltage output
Key lock and selection function : Achieve some or all of the keys locked and define the scope of partial keys to prevent misuse.
Protection function: Powered motor short circuit test; Input/output phase failure protection; Over current protection; voltage protection. Under voltage protection; Over heat protection ; Overload protection; braking resistor fault protection.
