ATV61HD18N4S337 Schneider Electric Variable Frequency Drives (VFD)

Schneider Electric ATV61HD18N4S337 is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter from the Altivar 61 series designed for variable speed and frequency control with U/F ratio adjustment options (2 points / 5 points / energy saving), sensorless flux vector control (standard / energy saving), and vector control without speed feedback capable of delivering 120% of the nominal motor torque. It features a built-in DC choke, an EMC filter (class C2), a built-in heatsink, and a coated version for enhanced durability. The supply voltage ranges from 323-528Vac, supporting 380Vac, 400Vac, 480Vac, and 500Vac nominal values. Its dimensions are H400mm x W230mm x D213mm, and it has a conformal coating for chemical resistance, classified as a reinforced version. The degree of protection is IP20 UL type 1. The rated current is 41A at 380Vac (12kHz), 34A at 460Vac (12kHz), with a maximum current of 49.2A for 60 seconds. It is designed for wall mounting and supports Modbus and CANopen communication protocols. This 3-phase (3P) network device outputs frequencies from 0.1 to 599 Hz. It includes 1 analog output (0-10Vdc / 0-20mA), 5 digital inputs (24Vdc; sink/source) plus 1 additional digital input programmable as discrete or PTC input, and 1 PWR safety input. There are also 2 digital outputs (1 C/O SPDT relay contact and 1 NO relay contact), along with 2 analog inputs (-10...+10Vdc and 0-10Vdc / 0-20mA). The current consumption is 45.5A at 380Vac and 37.5A at 480Vac, with a rated active power of 18.5kW and a rated power of 25HP.
