TECO-Westinghouse L510-101-H1-U Variable Frequency Drive

The TECO-Westinghouse L510-101-H1-U Variable Frequency Drive is a compact 1 HP micro VFD that converts 115 VAC single-phase input to 0–230 VAC three-phase output, enabling precise speed and torque control for three-phase motors. It supports 50/60 Hz input, draws up to 19 A, and delivers 4.3 A on the output with an output frequency range of 0–599 Hz, and a maximum motor rating of 1 HP (0.75 kW). The drive uses Sensorless Vector Control and V/Hz control, and includes built-in PID, Auto Torque Boost, Stall Prevention, Multi-Speed Operation, Electronic Thermal Protection, and Motor Auto-Tuning, plus RS-485 (Modbus RTU) communications for integration. Encased in an IP20 chassis (frame F2) for panel mounting, it measures about 5.67 × 4.65 × 5.84 in and weighs roughly 3.5 lb. Commonly installed in pumps, fans, conveyors, mixers, packaging machines, textile machinery, and machine tools, the L510-101-H1-U serves maintenance teams and system integrators performing repair, retrofit, or expansion of three-phase motor systems.
