VTU

Voltage Tracking Unit

Device Description

VTU (Voltage Tracking Unit) is a generation digital input module that provides voltage tracking in single phase or three phase systems. Digital input module has network analyzer specification that provides 4 channel voltage and 3 channel current input on device. In addition to network analyzer and voltage tracking, VTU provides to monitoring of energy parameters of single phase or three phase information that connects. Logical 1 and 0 informations can be set with VTU Configuration Software which voltage range will work. At the same time, power parameter may also be observed which is calculated as real time opening the door to a world of connectivity and control.
