Description
Johnson Controls P266CHA-100 Single Phase Condenser Fan Speed Control
The Johnson Controls P266CHA-100 is a single-phase condenser fan speed controller engineered to deliver precise, reliable fan speed modulation in commercial and industrial HVAC condensing applications. Designed for use with 380/460 Vac single-phase systems, this controller helps maintain optimal head pressure and system efficiency across varying ambient conditions — protecting compressors and maximizing refrigeration system performance year-round.
Key Specifications
- Voltage Rating: 380/460 Vac, Single Phase
- Maximum Output Amperes: 4A
- High VAC Triacs: 2
- Available Auxiliary Fan Control Circuits: 3
Features & Benefits
- Modulates condenser fan speed to maintain stable head pressure under varying load and ambient conditions
- Two high-VAC triacs provide robust, solid-state switching for reliable long-term performance
- Three available auxiliary fan control circuits offer flexibility for multi-fan condenser configurations
- Single-phase design suited for a wide range of commercial refrigeration and air conditioning condensing units
- Helps reduce energy consumption by running condenser fans only at the speed required by system demand
- Durable Johnson Controls construction built to withstand demanding HVAC/R environments
Application
The P266CHA-100 is ideal for HVAC technicians and contractors working on commercial condensing units, rooftop equipment, and refrigeration systems that require precise fan speed control. Its multi-circuit auxiliary capability makes it well suited for staged or multi-fan condenser arrangements where independent fan control is needed.
