10046890P1S Liebert Mod Motor

Overview

The Liebert 10046890P1S is an official OEM modulating motor and actuator designed for precision control within Liebert HVAC systems. This component is engineered to convert electrical energy into mechanical motion, allowing for the precise regulation of valves and dampers to maintain optimal airflow and temperature in critical environments like data centers. It serves as the direct replacement for the obsolete 146351P1S and Johnson Controls VA-7203-5001 models.

Features

• Direct OEM replacement ensures compatibility and ease of installation without the need for extensive wiring modifications
• Magnetic clutch provides a constant output force for positive valve close-off and protects the motor from damage during stall conditions
• High-precision feedback control via a 2K ohm position potentiometer for accurate positioning
• Durable construction designed to withstand the high-demand requirements of commercial and industrial HVAC applications
• Pre-wired configuration specifically matched for Liebert system wire harness connectors
