● A high-reliability and small-sized inverter.
● Support the 3-phase AC asynchronous motor and permanent magnet synchronous motor;
● A variety of international leading drive control technologies : the vector VF (VVF) control and speed sensorless vector control (SVC); speed output and torque output.
● A90 is suitable for air compressor, extruder, fan, pump application etc.
1. No need for derating at the ambient temperature of 50°C;
2. Small size, leading in the industry;
3. Wide speed range and high control accuracy: VF/1:50; SVC/1:200; rated speed: ±0.2%;
4. High load capacity in low-frequency band: VF/1Hz/150%, SVC/0.25Hz/150%;
5. Perfect protections: protections against the overcurrent, overvoltage, overload, overheating, etc
Technical Specifications of A90 Inverter
● Rated voltage of power supply: Three-phase AC 340-460V, three-phase/single-phase AC 200V-240V;
● Applicable motor: Three-phase AC asynchronous motor and permanent magnet synchronous motor.
Model List of A90 Inverter
★ Correct selection of the inverter: The rated output current of the inverter is greater than or equal to the rated current of the motor, taking into account the overload capacity.
★ The difference between the rated power of the inverter and that of the motor is usually recommended not to exceed two power segments.
★ When a high-power inverter is provided with a low-power motor, the motor parameters must be entered accurately to prevent the motor from damage as a result of overload.
