Its battery-powered operation and guided test sequences via WinSAM software make it ideal for field technicians, utility providers, and EV infrastructure developers.

Key Features:

Direct current measurement: up to 32A AC / 200A DC
Voltage measurement: up to 300V AC / 1000V DC
Connector types: Type 2 and CCS2 (EU)
Integrated safety and overcurrent detection
Temperature monitoring of high-current contacts
Battery-powered for independent operation
Fast setup with permanent connection to reference meter (MT3x0s2)
Controlled via tablet and WinSAM software

Stationary Systems for Testing AC Charging Stations

AC meter testing up to 120 A (AC) and 320 V (AC)
The MTS310 source and test system uses the Reference Meter EPZ303, which is capable of measuring AC currents of up to 120 A. The new digital measuring system of the STM4000 series serves as an “error calculator”, i.e. it determines the measurement deviation of the DUT. The system is extendable for additional test positions. A necessary DUT connection can be supplied on request.

Stationary Systems for Testing DC Charging Stations

DC meter testing up to 1000 A (DC) and 1200 V (DC)
The MTS780 source and test system uses the Reference Meter of the new s2 series (MT310s2), which, together with a high-precision DC transducer, forms a measuring unit capable of measuring DC currents of up to 1000 A. The reference meter serves not only as a reference device but also as an “error calculator”, i.e. it also determines the measurement deviation of the DUT. The system is extendable for additional test positions. A necessary DUT connection can be supplied on request.
