Product Description
3 3/4-dgt multi-range µP-ba-
sed controller for AC/DC cur-
rent measurements. Scaling
and setpoints are fully pro-
grammable by user-friendly
key-pad. The MDI 40 A in-
cludes peak/valley function
and password protection.
The housing is easy to mount
and ensures a protection de-
gree of IP 65.
