I55AE411F1AV11003S Lenze Variable Frequency Drives (VFD)

Lenze I55AE411F1AV11003S is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter within the Drives sub-range, designed for variable speed/frequency control, compact inverter DC-injection braking, brake management for brake control, S-ramps for smooth acceleration and deceleration, flying restart circuit, and PID controller functionality. It features a built-in RFI filter, safe torque off (STO) safety standard, I.O. conformal coating, and is designed for control cabinet or surface/wall mounting. The dimensions are H685mm x W258mm x D304mm. It supports Modbus RTU communication protocol and offers protection functions against overvoltage, leakage current, earth fault resistance, and overtemperature of the motor. The rated current varies with duty and voltage: 254A (light-duty; 400Vac), 216A (light-duty; 480Vac), 212A (heavy-duty; 400Vac), and 180A (heavy-duty; 480Vac). It operates on a supply voltage of 400Vac / 480Vac, with an ambient air temperature for operation of up to 45°C (at a switching frequency of 2kHz or 4kHz) and up to 40°C (at a switching frequency of 8kHz or 16kHz), and has a degree of protection of IP20. The network type is 3-phase (3P / 3AC) with a network frequency of 45-65 Hz (input) and 0-599 Hz (output). It includes 1 x analog output, 5 x digital inputs with flexible functionality, 1 x digital output, and 2 x analog inputs. The rated active power is 132kW (light-duty; 400-480Vac) and 110kW (heavy-duty; 400-480Vac), with a rated power of 180HP (light-duty; 400-480Vac) and 150HP (heavy-duty; 400-480Vac).
