Protection speed controller TRANSFORMER-BASED

adjustmentfor ventilationmagnetic

Most ZIEHL-ABEGG external rotor motors are voltage controllable. Transformer control units are available for simple and inexpensive speed control of these motors or fans. These are available in different versions. In addition to versions which only output the appropriate voltage via the setting of the 5-step switch, there are, for example, devices which can also control dampers or valves. Advanced devices also perform motor protection functions. Another major advantage of transformer-based control units is speed control without electromagnetic excitation in the motors. The products are therefore also recommended for noise-sensitive areas. Speed adjustment via built-in 5-stage transformer. Individual or parallel control of 3~ motors or fans. Ideally suited for combination with ZIEHL-ABEGG external rotor motors or fans. Easy-to-use, rugged system. Control without electro-magnetic motor noises. Easy-to-use speed controller with integrated 5-stage switch for rotational speed specification Devices with two 5-step switches, two speeds can be externally switched. Easy-to-use speed controller, with rotational speed specification via an external 0 – 10 V signal. Extended versions, with additional inputs and outputs Output range: 1~ transformers, 1.5 to 14 amps 3~ transformers, 2 to 14 amps
