The TECO FM50-1P5-C is a Fluxmaster 50 series micro AC inverter engineered for variable frequency motor control. It converts single-phase 100-120V AC input to three-phase 200-230V AC output, delivering 0.5 HP (0.4 kW) at 2.3 A continuous output current for constant torque applications. The drive employs Sinusoidal Wave PWM control across an adjustable 1-200 Hz frequency range, with 0.1 Hz resolution (0-99.9 Hz) and 1 Hz resolution (100-200 Hz) via digital operator interface. Six preset V/F patterns support diverse motor profiles and load characteristics.
Technical Specifications
• Input: Single-phase 100-120V AC, 50/60 Hz, maximum 10.0 A; tolerates voltage fluctuation of +10% to -15% and frequency variation of ±5%
• Output: Three-phase 200-230V AC; 2.3 A rated constant torque output
• Overload Rating: 150% of rated output current for 1 minute; instantaneous overcurrent capability approximately 200% of rated output
• Frequency Control: Adjustable 1-200 Hz range; carrier frequency selectable 4-16 kHz
• Acceleration/Deceleration: 0.1-999 seconds programmable
• Braking Torque: Approximately 20% (integrated, no external resistor required)
• KVA Rating: 0.88 KVA
• Enclosure: Compact chassis-style, IP20 rating
– Key Features
• Overvoltage protection (activation at 410 VDC output)
• Undervoltage protection (activation at 200 VDC output or below)
• Thermal protection via fin overheat thermostat
• Integrated stall prevention, ground fault detection, and short circuit protection
• Speed search capability for restart after momentary power loss (0-2 seconds)
• PNP source-type input logic; external 24V DC input supported
• Analog reference control at 0.06 Hz / 60 Hz resolution
– Typical Applications
Small motor variable speed control in panel-mounted industrial and commercial environments where environmental sealing is not required.
– Compatibility & Integration
Suitable for AC induction motors rated 0.5 HP. Single-phase input eliminates need for three-phase supply infrastructure on the input side.
