M-Bus level converters

With the M-Bus level converters from the MPW or MPW-IP series from STV Electronic, you can easily, safely and powerfully connect your controller, such as the Smart Manager 4.0 for energy data acquisition and control, to your M-Bus network,

Our level converters connect the meter data of your sensors and also the control of your actuators in the M-Bus network via the Ethernet interface and optionally via an additional serial interface (RS-232 or RS-485).

The parameters are set on the integrated website. If desired, this can be password-protected against unauthorized changes.

What is special about our level converters?

The devices have a narrow width. With a width of only 1DU, the MPW2 offers you the option of integrating up to two standard loads (1.5 mA each) into your control system. The MPW6 creates a maximum of 6 standard loads with a width of only 2TE, the MPW16 only requires a width of 3TE for 16 standard loads. All larger devices up to 128 standard loads are only 4HP wide.

All devices are characterized by simple commissioning. Devices with a serial interface (RS-232, RS-485 or USB) do not require any parameterization. The devices with an IP interface support IPv4 and IPv6 as well as MQTT and have a simple parameterization interface with additional diagnostic functions. They can also be parameterized remotely. You can find more information on this in the operating instructions in our downloads.

The high M-Bus voltage of 37-40 V enables large M-Bus networks to be operated safely. The intelligent controller takes over the management itself.
With M-Bus transmission rates from 300 to 38400 baud, the level converters are also suitable for fast M-Bus devices.

So you have the full control about your energy management and your resource consumption at all times and operate your production plants and buildings efficiently, even remotely.
