is a 3 kW (4 hp) variable speed drive from the Easy Altivar 310 range. This model is designed to handle slightly larger industrial loads while maintaining a compact footprint for space-constrained panels.
Core Performance Features
Dual Power Rating:
Heavy Duty (HD): 3 kW (4 hp) for high-starting torque applications.
Normal Duty (ND): 4 kW (5 hp) for applications with standard loads.
Torque & Control: Provides a starting torque of 150% at 3 Hz and transient overtorque of 170% to 200% of the nominal motor torque.
Control Profiles: Supports Sensorless Vector Control (SVC) for high precision, standard Voltage/Frequency (V/f), and Energy Saving quadratic U/f modes.
Braking Torque: Up to 150% of nominal torque with a braking resistor, and up to 70% without one
Physical Dimensions & Environmental Tolerance
The unit features an integrated cooling fan to manage the increased heat from higher power ratings.
