Lennox 15G19 Inverter
The Lennox 15G19 Inverter is a high-performance 3HP 460V variable frequency drive specifically engineered for commercial HVAC applications. As a pre-programmed Mitsubishi FR-D740-050-L3 equivalent, this unit provides precise motor speed control and torque management for LG/LC, SG/SC, KG/KC/KH, and TA/EL series rooftop units. This three-phase VFD optimizes energy efficiency by modulating the frequency of the compressor and supply fan motor, significantly reducing operational wear compared to across-the-line starters. For technicians performing a VFD field retrofit, the 15G19 features a compact footprint and is designed for direct integration with the Lennox Unit Controller system, supporting Multi-Stage Air Volume (MSAV) operations. Whether you are replacing a failed 615610-05 inverter or upgrading an existing belt drive assembly, this OEM Lennox part ensures the tightest control over static pressure and system airflow.
Key Benefits- Precise Frequency Modulation: Controls output frequency to maximize the energy efficiency of 3-horsepower 460VAC motors.
- OEM Compatibility: Pre-programmed specifically for Lennox commercial rooftop units, eliminating the need for complex field parameter mapping.
- Enhanced Component Protection: Reduces inrush current during startup, protecting the blower motor and drive components from mechanical stress.
- Advanced HVAC Integration: Fully compatible with Prodigy and CORE Lite unit controllers for seamless system communication.
- Compact Industrial Build: Durable enclosure designed to withstand the high-temperature environments of HVAC compressor compartments.
Which Lennox units is the 15G19 compatible with?
This inverter is a direct OEM replacement for several commercial series, specifically the LG/LC, SG/SC, and KG/KC/KH platforms requiring a 3HP 460V 3-phase drive.
Does this VFD require on-site programming?
The Lennox 15G19 comes pre-programmed for standard HVAC configurations. However, depending on your specific ECTO parameter settings or if used in a non-integrated application, minor adjustments via the VFD keypad may be necessary.
What safety precautions should be taken during installation?
Technicians must disconnect all power and wait at least 10 minutes for the internal capacitors to fully discharge before opening the VFD cover to prevent electrical shock.
