Function
Measuring current transformers STW2, STW3 and STW4 measure
the load current of a phase for the supply of medically used areas.
If several phases are present, then for each phase a measuring
current transformer is needed.
Evaluating devices for STW… are for example:
● ISOMETER® isoMED427P, transfer switching devices ATICS®…
● Load current monitors CMS460-D4
● Line isolation monitors LIM2010
Intended use
Measuring current transformers STW2, STW3 and STW4 are preferably used for the monitoring of power supply in medically used
areas. There they measure the load current and convert it into a signal usable for evaluating devices
