Speed fan controller RUE-2G

Overview
Transformer-based speed controllers for ZIEHL-ABEGG external-rotor motors and fans. Provide simple, cost-effective stepped speed control via an integrated 5-stage transformer. Available in single-phase and three-phase versions with variants offering additional I/O and motor protection functions. Suitable for noise-sensitive applications due to control without electromagnetic excitation.

Product specification
Speed adjustment via built-in 5-stage transformer. Individual or parallel control of 3~ motors or fans. Optional external 0–10 V input on selected models for continuous control.

Properties & special features

• Designed for use with ZIEHL-ABEGG external-rotor motors and fans.
• Simple, rugged design for industrial installation.
• Stepped speed selection without electromagnetic motor noise — recommended for noise-sensitive areas.
• Some models include outputs/inputs to control dampers or valves and provide motor protection.

Version / Output range

• 1~ transformers: 1.5 – 14 A
• 3~ transformers: 2 – 14 A

Scope of functions

• Integrated 5-stage rotary switch for direct speed selection; devices with two 5-step switches allow two externally selectable speeds.
• Models with external 0–10 V input for setpoint control.
• Extended variants with additional inputs/outputs for expanded control, some capable of driving dampers or valves.
• Advanced units offer motor protection functions.
