TECO-Westinghouse PA7300-5007-N1 Variable Frequency Drive

The TECO-Westinghouse PA7300-5007-N1 Variable Frequency Drive provides precise speed and torque control for three-phase AC motors in industrial fan and pump applications, enabling energy-efficient operation in centrifugal pumps, HVAC systems, cooling towers, water and wastewater treatment, and irrigation networks. This PA7300 series drive is designed for variable-torque applications and offers input 500–600 VAC (three-phase) and 50/60 Hz with an output range of 0–180 Hz, supporting up to 7.5 HP for variable-torque loads. It uses a Variable Frequency PWM Inverter control method and includes PID control, auto energy saving, and PID sleep mode to optimize process efficiency. The unit features a two-line LCD keypad display with copy function and supports optional communications cards (Modbus, Profibus, LonWorks, Metasys) with PA Link Software for programming and configuration. It provides overload capability of 120% rated current for variable-torque applications and comes in a NEMA 1 enclosure with certifications including UL, cUL, and CE. Compatible equipment includes pumps, centrifugal fans, cooling towers, HVAC systems, chillers, irrigation systems, and other industrial ventilation equipment; common replacements include TECO-Westinghouse MA7200-5007-N1, E510-5007-H3-N, and L510-5007-H3-N.
