Completely assembled measuring cases

Semi-permanent measuring or no space for a fixed power analyser?

Do you want to install a meter temporarily or semi-permanently or is there no room for a fixed energy meter in your installation? Fortop has a standard solution in the form of fixed measuring cabinets that are delivered completely assembled and tested. Connecting the measuring voltage and the current transformers is sufficient. 

The cabinets can be fitted with a power quality analyser or a power analyser, both in a panel-mounted and a DIN-rail version. The cabinets are supplied with a drawing, a connection diagram and the coding of terminals and components.

Measuring cabinet readout

Reading via a Local Ethernet Network

The metering cabinets are equipped with an Ethernet connection, allowing them to be integrated into the local network. Direct connections can be made to the meter for reading the embedded web interface or using the GridVis application. The meters can be easily integrated into higher-level systems using standard protocols such as Modbus TCP and BACnet/IP.

Remote Access via the Fortop VPN Service

If you want access to your metering cabinet independently of your own IT infrastructure, we can provide you with access to the energy meter through our VPN server. Through a VPN login on your laptop or workstation, you are guaranteed a secure and always available connection for a fixed monthly fee. The connection can be established via both a wired network and a 3G/4G/LTE network.

Data Logging and Web Reading via the Fortop Cloud Service DCEM Cloud

For a fixed monthly fee, we handle data storage and web visualization of key measurements, Voltage sags and current peaks, power quality reports, and energy consumption. Even in the event of a data connection loss, no data is lost because of local data storage. The web visualization includes an export function for all available measurements.
