Carlo Gavazzi WM50AV53HBC Multichannel Power Analyzer

Name: Carlo Gavazzi WM50AV53HBC Power Analyzer – Datasheet & Quote
Brand: Carlo Gavazzi
SKU: WM50AV53HBC

Description

Branch-level energy monitoring from one panel instrument

The WM50AV53HBC is the main unit of the Carlo Gavazzi WM50 multichannel power analyzer for single-phase, two-phase and three-phase systems. It measures the main line (voltage, current through CTs, power, energy, harmonics) and, with TCD12 split-core current sensors, up to 96 individual load channels, so one panel instrument can monitor every outgoing circuit of a distribution board or power distribution unit.

The TCD12 sensors are connected over a digital bus, which gives good immunity to disturbances and removes the need to wire dozens of current inputs individually. The unit has a wide backlit LCD, a touch keypad, detachable terminals and an optical port for configuration, and it keeps its own event and data log without an external datalogger. Two optional accessory modules add digital I/O or analog inputs and Modbus RTU or Modbus TCP/IP communication.

Where a multichannel analyzer fits

The usual applications are switchboards and PDUs where many loads share one incomer: data centres, hospitals, food storage, light industry and commercial buildings. One WM50 with TCD12 sensors replaces dozens of single-circuit meters and gives per-load energy data, alarms and harmonics through UCS or Modbus, for example into the Carlo Gavazzi VMU-C monitoring system.

Because the WM50 reads the main line through conventional 5 A CTs, the CT ratio and class determine the main line accuracy; the datasheet lists solid-core and split-core CTs from the CTD range. Each TCD12 sensor handles 12 channels, so eight sensors reach 96 channels.

What to confirm before ordering

The Carlo Gavazzi product page lists auxiliary supply options of 120 V AC and 220 to 240 V AC, while the datasheet states 100 to 277 V AC/DC; the datasheet figure is used above and the exact supply should be confirmed against the unit label. The ordering key in the datasheet (WM50 AV5 3 H BC) is shown graphically, so confirm the variant when requesting a quotation. TCD12 sensors, cables and accessory modules are ordered separately. For another multi-function meter, see the Janitza UMG 508, or browse the automation accessories category.

About brand

Carlo Gavazzi is an international group that designs, manufactures and markets electronic control components for building and industrial automation. The company was founded in Milan in 1931, and the publicly quoted holding company is headquartered in Steinhausen, Switzerland. Seven Star LLC, an independent supplier in Muscat, lists Carlo Gavazzi sensors, solid state contactors, energy meters and monitoring relays for panels and machines.

Carlo Gavazzi product families

The portfolio published by the group covers sensors, solid state relays, energy meters and analyzers, monitoring relays, soft starters, timers, power supplies and safety devices. Each family has a datasheet with ordering keys, ratings and dimensions, so an exact part number can be checked before ordering.

Ordering Carlo Gavazzi products: what we need

Send the complete part number, the quantity, the supply or load voltage and current, the mounting style and any approvals needed. For energy meters add the system type and communication port, and for solid state relays add the load type and the ambient temperature at the panel.
