Portable current sources and current-voltage sources

While testing of meter installations on-site often a sufficient load is missing to achieve reliable results. You can generate currents up to 120 A and voltages up to 500 V with our sources.

Brand new in our product range is the MT551 standard set – a complete predefined package for load simulation with the most common accessories.

An overview of the entire MT series, consisting of test meters, sources and test systems, can be found in our “MT series leaflet”.
