4.6 IG-MTU/IG-MTU-C/MTU-2-1
4.6.1 Description
Voltage transformer unit, for three wire system, system with separated Neutral or when galvanic separation
between generator or mains voltage and controller is required.
IG-MTU with voltage ratio 1 : 1, conversion accuracy ± 1.5%, phase shift ± 2°
IG-MTU-2-1 with voltage ratio 2 : 1, conversion accuracy ± 1.5%, phase shift ± 2°
IG-MTU-C with voltage ratio 1 : 1, conversion accuracy ± 3%, phase shift ± 3° .Additional filter for the
cases of extreme distortion of generator voltage by higher harmonics due to inverters etc.
