RM-ECd - ebm-papst, Manual 0-10v controller with display

The ebm-papst RM-ECd is a manual 0–10V speed controller designed for use with the full range of ebm-papst EC fans. Powered directly by the fan's 10 VDC motor output, no separate power supply required, it delivers stepless speed control from 0% to 100%, making it ideal for AHU and ventilation commissioning.

An integrated LCD screen displays the 0–10V control signal in real time for fast, accurate setup. For installations using a tacho fan, a DIP switch allows the display to show fan RPM instead, giving engineers the flexibility to work with the output that suits their application.

Key features:

• Stepless 0–10V manual speed control 0% to 100% range
• LCD display showing control voltage or RPM (DIP switch selectable)
• Controls multiple fans simultaneously at matched speed
• No separate power supply required, powered by a 10VDC fan motor output
• IP54 rated enclosure (RM-ECd); IP00 unboxed version available (CN1100)
• Cable entries: 4 × M16 or M20
• 4 mm mounting holes for panel or surface installation

Specifications:

• Part number: RM-ECd
• Supply voltage: 10 VDC
• Ambient temperature: −20 to +60 °C
• IP rating: IP54
• Dimensions (H × W × D): 94 × 94 × 55 mm

Typical Applications:

• AHU (air handling unit) fan speed adjustment during commissioning
• Standalone ventilation units requiring manual airflow control
• Extract or supply fan arrays where multiple EC fans run at a matched speed
• Plant rooms and roof-mounted ventilation, where a simple set-and-forget speed control is needed
• Refrigeration and cooling enclosures using ebm-papst EC fans
• Laboratory or cleanroom ventilation requiring precise, stepless airflow adjustment
• Data centre or server room cooling fans needing manual override control

Also available: fan speed regulators and HVAC controllers for a wide range of ventilation control applications.
