Schneider Electric ATV12H055M2 Variable Frequency Drive

Schneider Electric Altivar 12 ATV12H055M2 is a 0.55 kW (0.75 HP) single‑phase variable frequency drive designed for 200–240 VAC operation with an integrated heat sink. This 1‑phase drive from the Altivar 12 family provides open‑loop speed control for standard induction motors, delivering matched torque and speed for ventilation and pumping tasks while aiming to improve energy efficiency in these applications. It features an IP20 enclosure for indoor mounting and is specified for 0.55 kW output at 200–240 VAC (with regional variations listing 100–120 VAC configurations in some markets). EMC filtering options exist depending on configuration (integrated in some variants, or available without a filter in others), simplifying installation in compatible control panels. The unit emphasizes a compact, all‑in‑one form factor and straightforward setup, including user adjustments via a dial and an 8‑digit display, making it suitable for quick commissioning in small‑to‑medium drive applications where space is at a premium.
