Product Features

Dual-Inverter Drive Architecture

Independent compressor and fan inverter outputs simplify system design and improve matching between load demand, compressor capacity and fan operation.

Smooth Sensorless SVPWM Control

Sensorless SVPWM sinusoidal control reduces harmonics, vibration, torque ripple and noise for smooth operation.

Wide Speed Regulation Range

10-130 rps compressor speed regulation supports low-load to high-load HVAC and heat pump operation.

Comprehensive Protection Suite

Built-in protection covers current, voltage, temperature, phase loss, overspeed, startup and sensor faults.
