Active Front End VFD - 1LHX Phase Converting 25 - 150 HP

Phase Technologies 1LHX Series Variable Frequency Drive (VFD) 460 V, 25 - 150 HP, NEMA 1

Powerful. Efficient. Clean. The Phase Technologies 1LHX Series VFD sets a new standard for motor control, offering electrical contractors an advanced solution with superior power quality and robust performance. Featuring an active front end (AFE) and low harmonic design, the 1LHX series delivers cleaner, more efficient power that protects your equipment and complies with stringent electrical standards.

Key Features:

• Active Front End (AFE):
  Equipped with state-of-the-art AFE technology, the 1LHX Series ensures precise control and power conversion, improving system efficiency while minimizing power quality issues.
• Low Harmonic Operation:
  The low harmonic design reduces total harmonic distortion (THD), protecting sensitive equipment and meeting IEEE 519 compliance standards. This makes it ideal for facilities prioritizing clean power and minimizing interference with other devices.
• Improved Energy Efficiency:
  Lower harmonic distortion and power factor correction means reduced energy waste and better utilization of input power, resulting in significantly reduced operating costs.
• Single-Phase to Three-Phase Conversion:
  Delivers seamless conversion while maintaining optimal power quality, making it perfect for areas with limited three-phase availability.
• Rugged & Reliable:
  Designed to operate in demanding environments, with as much as 50% voltage imbalance, the 1LHX Series offers durable construction and integrated protection systems for maximum uptime and longevity.
• Multiple Control Methods:
  Comes standard with both v/f and direct torque control
• Flexible I/O:
  Analog Inputs: (2) 4 - 20 mA, (1) 0 - 10 VDC
  Digital Inputs: (4) programmable, expandable
  Relay Outputs: (4) programmable, (2) 30 VDC or 277 VAC, 10 A,
  (2) 30 VDC, 2 A or 125 VAC, 0.5 A
  Communication: Modbus RTU or Modbus IP, MS/TP or BACnet IP

Applications:

• Precision agricultural systems
• Commercial and industrial HVAC
