Advanced motor control & diagnostics

• Seven starting modes: soft start, current limit, full voltage, dual ramp, kick‑start, Accu‑Stop, and pump control – all digitally adjustable.
• Integrated HMI: backlit LCD screen shows metering data, fault logs, and parameter settings.
• External sensor support: connect a tachometer to display percentage of motor base speed.
• Status LEDs: six indicators for starting, at speed, stopping, stopped, alarm, and fault.
• Relay execution time: approximately 800 ms – programmable N.O. or N.C. contacts.

Frequently asked questions (FAQ)

• What is the difference between the 150-F108NBR and a standard starter?
  Unlike a simple contactor, this 150-F108NBR provides programmable soft starting, reducing mechanical shock and inrush current.
• Can I use this controller with a 230V AC motor?
  Yes, the input range covers 200‑460V AC, so it works with 230V, 380V, 400V, and 460V systems.
• Does the open enclosure require an additional cabinet?
  For most industrial environments we recommend mounting it inside a NEMA/IP54 enclosure to protect against dust and direct contact.
• How do I adjust the starting parameters?
  Use the built‑in LCD interface and navigation keys – no external programming tool needed.
• Do you have the 150-F108NBR in stock?
  Yes, we maintain inventory. Order now for shipment within 5 days via DHL, FedEx, or UPS.
• Is the 24V control supply included?
  The unit includes a 24V AC/DC control circuit; you just need to provide an external 24V power source.
• Can I monitor motor speed without an encoder?
  The controller calculates speed percentage based on voltage/frequency; for true RPM display you can add a tachometer input.
