Lenze ESMD551X2SFA 0.25kW 230V Single-Phase Compact Frequency Inverter

The Lenze ESMD551X2SFA is a genuine, factory-new frequency inverter from Lenze’s trusted SMD (8200 SMD) series, engineered as a compact, reliable solution for low-power industrial motor speed control. Designed for single-phase 230V input with a 0.25kW (1/3HP) power rating and 1.6A output current, this scalar (non-vector) VFD delivers precise linear or quadratic V/f control, making it ideal for a wide range of universal industrial automation applications.

• Power & Compatibility: 0.25kW rated power, 230V single-phase input, compatible with Lenze 8200 series drive systems, supporting standard three-phase motor operation
• Control Modes: Linear or quadratic V/f (scalar) control for flexible speed regulation, with adjustable carrier frequency up to 10kHz for ultra-quiet motor operation
• I/O & Connectivity: Equipped with programmable digital inputs/outputs, 0-10V / 4-20mA analog speed reference inputs, and a programmable relay output for start/stop control, external signal integration, and custom automation logic
• Protection & Reliability: Microprocessor-based motor thermal overload protection (eliminates extra hardware), 180% current limit with frequency foldback to prevent tripping, and robust industrial-grade construction for harsh factory environments
• User-Friendly Design: Highly visible LED display for real-time status monitoring, compact footprint (8.00 * 9.00 * 14.00 cm, 0.45kg weight) for space-saving installation, and simple parameter setup for fast commissioning
• Safety Compliance: Meets international industrial safety standards, with built-in electrical isolation and high-voltage warning markings for personnel and equipment protection
