Product Description
How to order EM11 DIN AV8 1 X O1 X
One-phase energy analyzer
with built-in configuration
push button and LCD data
displaying; particularly indicated for active and reactive
energy metering and for cost
allocation. Housing for DINrail mounting, IP40 (front)
protection degree. Direct
connection up to 32A.
Moreover the meter can be
provided with either pulse
output proportional to the
active energy being measured or alarm control on
the available instantaneous
variables.
