WM23 96 is a modular power quality analyzer that allows

the operator to continuously monitor the mains. All meas-

urements with a direct connection up to 830VAC (phase-

phase), up to 20kV (VT connection) and up to 5.000A (CT

connection) allow the operator to use WM23-96 in all the

light and medium industry applications. This flexible instru-

ment has a standard IP65 protection degree, a 0.5 accuracy

class, an FFT analysis up to the 16th harmonics and, on

request, up to 2 alarms, one analogue output and one

RS422/485 or RS232 communication port.

WM23 96 can be equipped with different modules like the

three digital input one. Two of those inputs can be connected

to the official Watt-hour meter to synchronise the W and VA

demand calculation, while the last input can be used to lock

the programming of the equipment.

This power quality analyzer is able to show any single current

and voltage total harmonic distortion on which it is possible

to connect an alarm output. The wide LCD display with high

contrast feature is able to show all the measurements and in

addition the recording of the MAX active powers: W

L3, (on request A
