SMU SMU/I

Current Transformer and transducer in one housing

• Up to 600 A

• Standard analogue output 0(4)-20 mA / 0(2)-10 V

Application

The measured quantity (i.e. primary current) is galvanically insulated (5kV/1

min), rectified (mean value principle) and converted into a proportional and

load-independent DC signal current (or voltage). The passive type SMU does

not require auxiliary supply. The active SMU/I connects to a auxiliary supply

of 230 VAC or 24 VDC. These information have to indicated on the order.

SMU: Design with 0-20 mA or 0-10 V output

without auxiliary supply

SMU/I: Design with 4-20 mA output and auxiliary supply

230 VAC or 24 VDC (indication on the order)

Snap-on mounting for DIN- rail, mounting brackets for mounting plates and

screws for the busbar fixing are included in delivery.
