ATV71HD18N4383 Schneider Electric Variable Frequency Drives (VFD)

Schneider Electric ATV71HD18N4383 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 71 series designed for synchronous motor control. It features a built-in DC choke, EMC filter, and heatsink, offering variable speed/frequency drive capabilities with U/F ratio (2 points / 5 points), sensorless flux vector control, ENA System, and vector control with or without speed feedback. This model can deliver 220% of the nominal motor torque for 2 seconds and 170% of the nominal motor torque for 60 seconds. It operates on a supply voltage of 323-528Vac (380Vac / 400Vac / 480Vac / 500Vac nom.) and has dimensions of H400mm x W230mm x D213mm. The ATV71HD18N4383 is designed for wall mounting and has a degree of protection of IP20, IP21, and UL type 1. It supports Modbus and CANopen communication protocols and is compatible with a 3-phase (3P) network, offering an output frequency range of 0.1-599 Hz. The drive includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) programmable as LI1-LI5, 1 digital input programmable as discrete or PTC input, and 1 PWR safety input, along with 1 digital output (C/O SPDT relay contact) and 2 digital outputs (NO relay contacts). It also features 1 analog input (-10...+10Vdc) and 1 analog input (0-10Vdc / 0-20mA). The rated current is 41A at 380Vac (4kHz), 34A at 460Vac (4kHz), with a maximum current of 67.7A for 2 seconds and 61.5A for 60 seconds. The current consumption is 45.5A at 380Vac and 37.5A at 480Vac, with a rated active power of 18.5kW and rated power of 25HP.
