I55AE137B1AV11003S

Lenze I55AE137B1AV11003S is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter within the Drives sub-range, designed for variable speed and 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 dimensions of H155mm x W60mm x D130mm. The communication protocol supported is Modbus RTU, with protection functions including overvoltage category, leakage current, earth fault resistance, and overtemperature of motor. It has a rated current of 2.4A for heavy-duty applications at 230-240Vac, with a supply voltage of 230Vac / 240Vac. The mounting mode is suitable for control cabinet or surface/wall mounting. The ambient air temperature for operation varies with the switching frequency, allowing a maximum of 45°C at 2kHz or 4kHz and 40°C at 8kHz or 16kHz. It has an IP20 degree of protection, operates on a single-phase / 1P network with a frequency of 45-65 Hz (input) and 0-599 Hz (output), and includes 1 x analog output, multiple digital inputs with optional uses, 1 x digital output, and 2 x analog inputs with optional uses. The rated active power is 0.37kW, and the rated power is 1/2HP for heavy-duty applications at 230-240Vac.
