Key Features
Rated power is 7.50 kW | 10.00 hp (LO) or 5.50 kW | 7.50 hp (HO). LO overload is 150% for 3s, 110% for 57s and 100% for 240s; HO overload is 200% for 3s, 150% for 57s and 100% for 240s.
Input is 3 AC, 380 … 480 V +10 % -20 % at 47 … 63 Hz. Output is 3 AC with 400V IEC | 480V NEC rated voltage and maximum output current of 25.00 A.
The converter has 6 standard digital inputs, 1 fail-safe digital input, 1 relay changeover contact, 1 transistor output, 1 differential input, 1 non-isolated analog output and PROFIBUS DP communication.
Supported techniques include V/f linear / square-law / parameterizable, V/f with flux current control (FCC), V/f ECO linear / square-law and sensorless vector control. Vector control, with sensor; encoderless torque control; and torque control, with encoder are not supported.
Line-side, motor-end and DC-link connections use plug-in screw terminals. Protection is IP20 / UL open type, with an integrated Class A filter and integrated fan air cooling.
