The low-voltage voltage transformers from MBS AG are especially voltage-resistant and highly efficient thanks to their physical structure. They also offer class-accurate harmonics transmission up to 10 kHz. Our production range includes single-pole insulated voltage transformers for connection between conductors and earth, and dual-pole insulated voltage transformers for connection between conductor and conductor.

The 1-phase and 3-phase energy meters M1Pro and M3Pro Professional set new standards in the field of DIN rail energy meters.

The energy meters are available with S0 output, M-Bus, Modbus, KNX and LAN -TCP/IP interface as energy transformer meter as well as for direct measurement with the interfaces S0 output, M-Bus and Modbus.

The devices are ideally suited for energy and power measurement, demand and load analysis, energy controlling, cost center management as well as billing applications and energy management according to ISO 50001.

All equipment systems devices have MID approval (suitable for billing purposes).

Production at MBS AG currently includes over 10,000 low-voltage current converters in the 0.5 series with a maximum operating voltage of 0.72 kV or 1.2 kV in the case of the CTB type series.

All products are manufactured in compliance with the defined technical requirements from DIN EN 61869-1/2, VDE 0414-9-1/2 and DIN 42600. The current version of the standards quoted is used.

The main areas of use for our products are mechanical and plant engineering, ship-building, and wind energy.

Thanks to our extensive portfolio of products, as well as personalised advice from our team of specialist engineers and sales consultants, you will find the ideal low-voltage current transformer for whatever application you are planning.

• Minimal losses for measuring current with low consumption
• For accurate measurements at low currents, high precision in the small-signal band is required
• With a wide frequency range, the current signal may be captured even when it changes rapidly - compliance with IEC 61869-1 specifications (up to 3 kHz)
• New technology in tried-and-true housings—over 50 designs
• Can be used with all common universal measurement instruments
• Short-circuiting is not necessary for open functioning of the devices, which saves time and money
• Time and money are saved with passive small signal converters while no additional auxiliary voltage is needed

Medium-voltage current transformers for indoor applications that transfer one or more network-side primary currents proportionally and true to phase into standardised secondary currents. These are isolated in cast resin and, alongside their primary function as current transformers, also act as busbar supports. These current transformers can be used both for measuring and protection purposes.

The medium-voltage current transformers are also available as multi-core transformers. The maximum possible number of cores depends on the output selected and the accuracy class, which specify the core volume. The current transformers are optionally available with primary or secondary switching.

The current transformers with primary switching offer the option of choosing between two primary nominal currents, depending on the connection of the primary connections through parallel or serial circuits. The primary-side nominal currents can be achieved only in a ratio of 1:2. For current transformers having secondary switching, the switching is made possible by one or more pickups. As a result, the primary-side nominal currents can also be achieved in various ratios.
