Manager’s Insight

• This inverter fills a niche for low-power, single-phase applications.
• Customers often choose it for packaging machines and small mixers.
• Stock levels are stable, and lead times are short.
• Pair it with a line reactor if the supply is noisy.
• It is not a servo drive, so avoid position control tasks.

Best Applications and Equipment

• Small conveyors and belt feeders.
• Centrifugal pumps up to 0.75 kW.
• Low-power fans and blowers.
• Simple winding and rewinding machines.
• Bench-top test rigs and educational kits.
• Woodworking and light metal cutting tools.

FAQ

• Q: Can this inverter run a 1.5 kW motor?
  A: No. The maximum motor capacity is 0.75 kW.
• Q: What is the input phase?
  A: It accepts single-phase 200–240V.
• Q: Does it come with a braking resistor?
  A: No. You can add an external braking resistor if needed.
• Q: How do I reset a fault?
  A: Press the stop/reset key on the panel or cycle power.
• Q: Is this drive suitable for a CNC spindle?
  A: Not really. It lacks the high-speed and positioning features of a spindle drive.
• Q: What wire size should I use?
  A: 1.5 mm² to 2.5 mm² copper wire is typical for this power level.
• Q: Can I mount it sideways?
  A: No. Keep it vertical for proper cooling.
• Q: Does it support Modbus?
  A: No built-in Modbus. Use optional communication cards if needed.
• Q: How do I choose between this and a 1.5 kW model?
  A: Match the inverter to your motor kW. For 0.75 kW, choose this unit.
• Q: What if the motor runs in reverse?
  A: Swap any two output wires (U, V, W) or change the direction parameter.

Buying Guide

• Check your motor nameplate for kW and current first.
• Confirm your supply is single-phase 200–240V.
• Decide if you need a keypad or remote operation.
• Allow space for heat dissipation inside the panel.
• Order a braking resistor only if your load needs fast stops.
• Keep a spare unit if downtime is costly.
