SP4401-HF Nidec Variable Frequency Drives (VFD)

Out if stock but available for backorder.

NIDEC SP4401-HF is a Variable Speed/Frequency Drive (VSD/VFD) / Inverter designed for high frequency applications up to 3000Hz max in open-loop configurations, including a single Safe Torque Off (STO) and air cooling. It features a frame size of 4, with dimensions H21.53" x W12.2" x D11.73" (H547mm x W310mm x D298mm), and operates on a supply voltage of 380Vac-480Vac (400Vac / 415Vac). The rated current is 68A under normal duty and 60A under heavy-duty conditions. This wall-mounted unit is designed to operate within an ambient air temperature range of 0°C to +40°C and has a degree of protection rated at IP20 NEMA 1. It supports Modbus RTU RS-485 communication protocol, with a network frequency of 48-65 Hz on the supply input and 0-3000 Hz on the output. The SP4401-HF includes 3 x digital outputs (0-24Vdc; source), 1 x digital output (2A / 240Vac; source; relay contact type), 3 x digital inputs (0-24Vdc), and 3 x additional digital inputs (0-24Vdc). Analog interface options include 1 x analog input (-9.8Vdc...9.8Vdc; differential) with 16-bit conversion resolution and 2 x analog inputs (0-20mA / 4-20mA / -9.8Vdc...9.8Vdc; single-ended) with 10-bit conversion resolution, alongside 2 x analog outputs (0-20mA / 4-20mA / -10Vdc...10Vdc; single-ended; source) also with 10-bit conversion resolution. The rated active power is 37kW under normal duty and 30kW under heavy-duty, with a rated power of 50HP for both conditions.
