Ordering Key WM2-96 AV53DXXX
µP-based
modular
power
analyzer with a built-in con-
figuration key-pad. The pow-
er, power factor, current and
voltage are system and sin-
gle phase measurements and
indications. The housing is
easy to mount on a panel
and ensures a degree of pro-
tection (front) of IP 65.
