208/230V Single Phase: This refers to units that operate on a single alternating current (AC) phase. Voltage can vary slightly depending on conditions, but generally ranges between 208V to 230V. These units are common in residential and light commercial applications where three-phase power is not available or necessary.
208/230V 3 Phase: These units utilize three phases of alternating current. They typically operate at a higher voltage range of 208V to 230V per phase, making them suitable for larger commercial and industrial HVAC systems. Three-phase power provides smoother operation, better efficiency, and the ability to handle larger loads compared to single-phase systems.
