Power analyzer for three-phase systems

Description

WM15 is a power analyzer for single-, two- and

three-phase systems.

Depending on the model, WM15 is equipped with a

static output (pulse or alarm) or with a static output

and a Modbus RTU communication port.

The self-powered version can be installed on

systems up to 415 V L-L (400 V L-L for MID

models), while the version with auxiliary power

supply can be installed on systems up to 600 V

L-L.

In combination with VMUBM2US1B1C, collected

data can be transmitted via M-Bus.

Benefits

•

Enhanced readability. The backlit graphical display

allows the size of the digits to be adapted to the displayed

variable. The instantaneous values of the current are

also shown by a bar graph to have the plant situation at

a glance.

•

Easy navigation. The setup and navigation of the

pages are very intuitive thanks to the user interface

with 4 mechanical push buttons. In addition, the

slideshow function automatically displays the desired

measurements in sequence without having to use the

keypad.

•

Quick setup. Wizard and wiring correction on first

startup, UCS mobile app for setup via OptoProg and

optical port are some of the advantages allowing a quick,

guided and errorless installations and commissioning.

UCS software is available for free download.

•

Accurate measurement. It is compliant with the

international accuracy standard IEC/EN62053-21, and

the IEC/EN61557-12 performance requirements (active

power and active energy).

•

Fiscal metrology. WM15 configuration access can be

locked and terminals can be sealed in case of a MID

certified model for fiscal metering.

•

Installation flexibility. WM15 is suitable for single-

phase, two-phase, three-phase and wild-leg systems

with different voltage levels and grid frequencies used

worldwide.

Applications

WM15 can be installed in any switchboard to control energy consumption, main electrical variables and

harmonic distortion.

In panel boards, where typically three analogical ammeters are installed to give a visual feedback of the

system status, WM15 provides the same information on the matrix display by means of the bar graphs.

When used to monitor a single machine, WM15 relates the energy consumption with the operating hours

to schedule maintenance and detect faults. Moreover, the reset of partial counters allows to monitor each

machine cycle.

Thanks to the MID certification, it can also be used for fiscal metrology.
