Schneider Electric ATV16U18N4 AC Variable Frequency Drive

Schneider Electric ATV16U18N4 Altivar 16 AC drive delivers 0.75 kW (1 HP) variable-speed control for three‑phase motors on 380–500 V networks with an IP31 enclosure for panel installations. This compact drive operates on 50/60 Hz input and provides an output frequency range of 0.5–400 Hz, with a nominal switching frequency of 4 kHz (12–16 kHz with derating; 2–12 kHz adjustable). Electrical ratings include line current about 3.9 A at 380 V and 3.5 A at 500 V, with continuous output current of 2.3 A (380 V) or 2.1 A (500 V) and about 5 kVA apparent power at 400 V. Communication is via Modbus over a 1×RJ45 port with 2‑wire RS‑485 in RTU framing, baud options of 9600 or 19200 bps, and configurable parity. Dimensions measure 200 mm high by 180 mm wide by 144 mm deep; this Altivar 16 model is intended for control of asynchronous motors in applications such as fans, pumps, and conveyors on 400/460 V three‑phase systems.
